Abstract
A novel anatomically shaped ("anatomical") woodworking chisel handle was developed for wood scraping operation. 18 students participated in an evaluation study to compare the new handle against seven readymade handles of ¾-inch bench chisels in the context of a standard wood scraping task. A comfort questionnaire for hand tools (CQH) and a hand-based pain map were used for evaluating and comparing the handles. 'Functionality' and 'sweating' were found to be the most and least important comfort concerns, respectively. Maximum pain was reported at distal digit 1, and least pain at proximal digit 4. The anatomical handle was rated best for most of the comfort descriptors, least painful for most hand regions and took the least time for a standardized task.

Abstract
INTRODUCTION A rate-based understanding of home care aides' adverse occupational outcomes related to their work location and care tasks is lacking. METHODS Within a 30-month, dynamic cohort of 43 394 home care aides in Washington State, injury rates were calculated by aides' demographic and work characteristics. Injury narratives and focus groups provided contextual detail. RESULTS Injury rates were higher for home care aides categorized as female, white, 50 to <65 years old, less experienced, with a primary language of English, and working through an agency (versus individual providers). In addition to direct occupational hazards, variability in workload, income, and supervisory/social support is of concern. CONCLUSIONS Policies should address the roles and training of home care aides, consumers, and managers/supervisors. Home care aides' improved access to often-existing resources to identify, manage, and eliminate occupational hazards is called for to prevent injuries and address concerns related to the vulnerability of this needed workforce.

Abstract
OBJECTIVE The study was conducted to assess an intervention suggested by the workers to reduce the physical or ergonomic exposures of the drywall installation task. METHODS The drywall installers were asked to brainstorm on innovative ideas that could reduce their ergonomic exposures during the drywall installation work. The workers proposed the idea of using a 'deadman' (narrow panel piece) to hold the panels to the ceiling while installing them. The researcher collected quantitative exposure data (PATH, 3DSSPP) at the baseline and intervention phases and compared the phases to find out any change in the exposure while using the 'deadman'. RESULTS Results showed that ergonomic exposures (such as overhead arm and awkward trunk postures and heavy load handling) were reduced at the intervention phase while using the 'deadman' with an electrically operated lift. CONCLUSION The concept of the 'deadman', which was shown to help reduce musculoskeletal exposures during ceiling installation, can be used to fabricate a permanent ergonomic tool to support the ceiling drywall panel.

Abstract
Three different methodologies: work sampling, computer simulation and biomechanical modeling, were integrated to study the physical demands of drywall installation. PATH (Posture, Activity, Tools, and Handling), a work-sampling based method, was used to quantify the percent of time that the drywall installers were conducting different activities with different body segment (trunk, arm, and leg) postures. Utilizing Monte-Carlo simulation to convert the categorical PATH data into continuous variables as inputs for the biomechanical models, the required muscle contraction forces and joint reaction forces at the low back (L4/L5) and shoulder (glenohumeral and sternoclavicular joints) were estimated for a typical eight-hour workday. To demonstrate the robustness of this modeling approach, a sensitivity analysis was conducted to examine the impact of some quantitative assumptions that have been made to facilitate the modeling approach. The results indicated that the modeling approach seemed to be the most sensitive to both the distribution of work cycles for a typical eight-hour workday and the distribution and values of Euler angles that are used to determine the "shoulder rhythm." Other assumptions including the distribution of trunk postures did not appear to have a significant impact on the model outputs. It was concluded that the integrated approach might provide an applicable examination of physical loads during the non-routine construction work, especially for those operations/tasks that have certain patterns/sequences for the workers to follow.

Abstract
BACKGROUND Musculoskeletal symptoms and disorders (MSDIs) are common reasons for visits to medical providers in the general population and they are common work-related complaints. Prior reports raise concerns as to whether declines in workers' compensation (WC) rates represent true improvement in occupational health and safety or shifting of care to other payment systems. METHODS By linking administrative records, we compared patterns of WC claims and private health care utilization for disorders of the upper extremity (UE) and knee among a large cohort of union carpenters over a 20-year period. RESULTS As WC claim rates declined, private health care utilization increased. The increase was muted somewhat but sustained when adjusting for other patterns of health care utilization. CONCLUSIONS Findings suggest the decline of WC claim rates do not solely represent improved occupational safety in this population, but also a considerable shifting of care to their private insurance coverage over time.

Abstract
BACKGROUND Numerous aspects of construction place workers at risk of musculoskeletal disorders and injuries (MSDIs). Work organization and the nature of MSDIs create surveillance challenges. METHODS By linking union records with workers' compensation claims, we examined 20-year patterns of MSDIs involving the upper extremity (UE) and the knee among a large carpenter cohort. RESULTS MSDIs were common and accounted for a disproportionate share of paid lost work time (PLT) claims; UE MSDIs were three times more common than those of the knee. Rates declined markedly over time and were most pronounced for MSDIs of the knee with PLT. Patterns of risk varied by extremity, as well as by age, gender, union tenure, and predominant work. Carpenters in drywall installation accounted for the greatest public health burden. CONCLUSIONS A combination of factors likely account for the patterns observed over time and across worker characteristics. Drywall installers are an intervention priority.

Abstract
BACKGROUND Drywall installers are at high risk for work-related falls from height (FFH). METHODS We defined a 20-year (1989-2008) cohort of 5,073 union drywall carpenters in Washington State, their worker-hours, and FFH. FFH rate patterns were examined using Poisson regression. RESULTS Drywall installers' FFH rates declined over time and varied little by worker age and time in the union. However, among FFH involving drywall sheets, workers with <10 union years were at high risk. Narratives consistently described the surface from which workers fell, commonly scaffolds (33%), ladders (21%), and stilts (13%). Work task, height fallen, protective equipment use, work speed, weather, influence of other workers/workgroups, and tool/equipment specifics were not often reported. PRACTICAL APPLICATIONS In addition to continued efforts to prevent falls from scaffolds and ladders, efforts should address stilt use and less experienced workers who may have greater exposure. Consistency in reported narrative elements may improve FFH risk factor identification and prevention effort evaluation.

Abstract
BACKGROUND Falls from height (FFH) are a longstanding, serious problem in construction. METHODS We report workers' compensation (WC) payments associated with FFH among a cohort (n = 24,830; 1989-2008) of carpenters. Mean/median payments, cost rates, and adjusted rate ratios based on hours worked were calculated using negative-binomial regression. RESULTS Over the 20-year period FFH accounted for $66.6 million in WC payments or $700 per year for each full-time equivalent (2,000 hr of work). FFH were responsible for 5.5% of injuries but 15.1% of costs. Cost declines were observed, but not monotonically. Reductions were more pronounced for indemnity than medical care. Mean costs were 2.3 times greater among carpenters over 50 than those under 30; cost rates were only modestly higher. CONCLUSIONS Significant progress has been made in reducing WC payments associated with FFH in this cohort particularly through 1996; primary gains reflect reduction in frequency of falls. FFH that occur remain costly.

Abstract
OBJECTIVE We evaluated work-related injuries involving a hand or fingers and associated costs among a cohort of 24,830 carpenters between 1989 and 2008. METHODS Injury rates and rate ratios were calculated by using Poisson regression to explore higher risk on the basis of age, sex, time in the union, predominant work, and calendar time. Negative binomial regression was used to model dollars paid per claim after adjustment for inflation and discounting. RESULTS Hand injuries accounted for 21.1% of reported injuries and 9.5% of paid lost time injuries. Older carpenters had proportionately more amputations, fractures, and multiple injuries, but their rates of these more severe injuries were not higher. Costs exceeded $21 million, a cost burden of $0.11 per hour worked. CONCLUSIONS Older carpenters' higher proportion of serious injuries in the absence of higher rates likely reflects age-related reporting differences.

Abstract
INTRODUCTION Construction workers are at high risk of work-related musculoskeletal back disorders, and research suggests medical care and costs associated with these conditions may be covered by sources other than workers' compensation (WC). Little is known about the back injury experience and care seeking behavior among drywall installers, a high-risk workgroup regularly exposed to repetitive activities, awkward postures, and handling heavy building materials. METHODS Among a cohort of 24,830 Washington State union carpenters (1989-2008), including 5,073 drywall installers, we identified WC claims, visits for health care covered through union-provided health insurance and time at risk. Rates of work-related overexertion back injuries (defined using WC claims data) and health care utilization for musculoskeletal back disorders covered by private health insurance were examined and contrasted over time and by worker characteristics, stratified by type of work (drywall installation, other carpentry). RESULTS Drywall installers' work-related overexertion back injury rates exceeded those of other carpenters (adjusted IRR 1.63, 95% CI 1.48-1.78). For both carpentry groups, rates declined significantly over time. In contrast, rates of private healthcare utilization for musculoskeletal back disorders were similar for drywall installers compared to other carpenters; they increased over time (after the mid-1990s), with increasing years in the union, and with increasing numbers of work-related overexertion back injuries. CONCLUSIONS Observed declines over time in the rate of work-related overexertion back injury, as based on WC claims data, is encouraging. However, results add to the growing literature suggesting care for work-related conditions may be being sought outside of the WC system.

Abstract
BACKGROUND Falls from height (FFH) continue to cause significant morbidity and mortality across the construction industry. METHODS By linking data on work hours with workers' compensation records, rates of work-related injuries resulting from FFH and associated days away from work were evaluated among a large cohort (n = 24,830) of union carpenters in Washington State from 1989 to 2008. Using Poisson regression we assessed rates of FFH over the 20-year period while adjusting for temporal trend in other work-related injuries. Patterns of paid lost days (PLDs) were assessed with negative binomial regression. RESULTS Crude rates of FFH decreased 82% over the 20-year period. Reductions were more modest and without demonstrable change since 1996 when adjusting for the temporal reduction in other injuries. Younger workers had higher injury rates; older workers lost more days following falls. Rates of PLDs associated with falls decreased over time, but there was not a consistent decline in mean lost days per fall. CONCLUSION These patterns are consistent with decreased FFH for several years surrounding state (1991) and then federal (1994) fall standards; the decline during this time period exceeded those seen in injury rates overall in this cohort. While crude rates of FFH have continued to decline, the decline is not as substantial as that seen for other types of injuries. This could reflect a variety of things including more global efforts designed to control risk (site planning, safety accountability) and changes in reporting practices.

Abstract
BACKGROUND Drywall installers are at high-risk of work-related injury. Comprehensive descriptive epidemiology of injuries among drywall installers, particularly over time, is lacking. METHODS We identified worker-hours and reported and accepted workers' compensation (WC) claims for a 20-year (1989-2008) cohort of 24,830 Washington State union carpenters. Stratified by predominant type of work (drywall installation, other carpentry), work-related injury rates were examined over calendar time and by worker characteristics. Expert interviews provided contextual details. RESULTS Drywall installers' injury rates, higher than those of other carpenters, declined substantially over this period by 73.6%. Common injury mechanisms were struck by/against, overexertion and falls. Drywall material was considered a contributing factor in 19.7% of injuries. One-third of these drywall material-related injuries resulted in paid lost time, compared to 19.4% of injuries from other sources. Rates of injury were particularly high among workers with 2 to <4 years in the union. Notable declines over time in rates of overexertion injury in which drywall material was a contributing factor were still observed after controlling for secular temporal trends. Experts highlighted changes over the past 20 years that improved both work safety and, in some cases, production. CONCLUSIONS Declines in drywall installers' injury rates over time likely reflect, in part, enhanced workplace safety, including efforts to reduce overexertion hazards associated with handling drywall. Continued injury prevention efforts are needed, particularly for less tenured workers. Given the potential for under-reporting to WC, additional sources of health outcomes data may provide a more complete picture of workers' health.

Abstract
OBJECTIVE To characterize work-related knee injuries treated in US emergency departments (EDs). METHODS We characterized work-related knee injuries treated in EDs in 2007 and examined trends from 1998 to 2007 by using the National Electronic Injury Surveillance System-occupational supplement. RESULTS In 2007, 184,300 (± 54,000; 95% confidence interval) occupational knee injuries were treated in US EDs, accounting for 5% of the 3.4 (± 0.9) million ED-treated occupational injuries. The ED-treated knee injury rate was 13 (± 4) injuries per 10,000 full-time equivalent workers. Younger workers and older female workers had high rates. Strains/sprains and contusions/abrasions were common-frequently resulting from falls and bodily reaction/overexertion events. Knee injury rates declined from 1998 through 2007. CONCLUSIONS Knee injury prevention should emphasize reducing falls and bodily reaction/overexertion events, particularly among all youth and older women.

BACKGROUND Individuals who work in the construction industry are at high risk of occupational injury. Robust surveillance systems are needed to monitor the experiences of these workers over time. METHODS We updated important surveillance data for a unique occupational cohort of union construction workers to provide information on long-term trends in their reported work-related injuries and conditions. Combining administrative data sources, we identified a dynamic cohort of union carpenters who worked in Washington State from 1989 through 2008, their hours worked by month, and their workers' compensation claims. Incidence rates of reported work-related injuries and illnesses were examined. Poisson regression was used to assess risk by categories of age, gender, time in the union, and calendar time contrasting medical only and paid lost time claims. RESULTS Over the 20-year study period, 24,830 carpenters worked 192.4 million work hours. Work-related injuries resulting in medical care or paid lost time (PLT) from work occurred at a rate of 24.3 per 200,000 hr worked (95% CI: 23.5-25.0). Medical only claims declined 62% and PLT claims declined 77%; more substantive declines were seen for injuries resulting from being struck and falls to a lower level than from overexertion with lifting. Differences in risk based on union tenure and age diminished over time as well. CONCLUSIONS Significant declines in rates of reported work-related injuries and illnesses were observed over the 20-year period among these union carpenters. Greater declines were observed among workers with less union tenure and for claims resulting in PLT.

Abstract
OBJECTIVE Low back pain (LBP) is a leading cause of lost work time and has been recognized as America's number one workplace safety challenge. Low back pain is occurring at epidemic proportions among construction workers, and minority populations have been underinvestigated for risk of back injury. This project investigated the multiple potential risk factors for occupational LBP among Hispanic residential carpenters. METHODS This investigation evaluated 241 Hispanic residential framing carpenters. Data for this study were collected using a 91-question survey. End points of interest included point, annual, and lifetime prevalence of LBP. RESULTS Nineteen percent of respondents reported they had an episode of LBP in their lifetime. CONCLUSIONS Hispanic residential carpenters reported less than expected prevalence of LBP compared with non-Hispanic counterparts in the same trade and location. Job tasks and personal and workplace risk factors, including psychological and morphological characteristics, affect the prevalence of LBP among Hispanic framing carpenters.

Abstract
The ILO has a mandate to protect workers against sickness, diseases and injuries due to workplace hazards and risks including ergonomic and work organization risk factors. One of the main functions for the ILO is to develop international standards related to labour and work. ILO standards have exerted considerable influence on the laws and regulations of member States. The ILO standards take the form of international Conventions and Recommendations. ILO Conventions and Recommendations relevant to protection of workers against ergonomic risk factors at the workplace include Convention No. 127 and Recommendation No.128 which specify the international requirements concerning the manual transport of a load. To help member States in applying the ILO standards, the ILO produces practical guides and training manuals on ergonomics at work and collects and analyses national practices and laws on ergonomics at the workplace. The ILO also conducts technical cooperation activities in many countries on ergonomics to support and strengthen the capacities of its tripartite constituents in dealing with workplace ergonomic and work organization risks. The ILO's technical cooperation activities give priorities on the promotion of voluntary, participatory and action-oriented actions to improve working conditions and work organizations of the small and medium sized enterprises. This paper reviews ILO's policies and activities on ergonomics in relation to occupational safety and health and prescribes ILO's considerations for its future work on ergonomics.

Abstract
Increasingly, the occupational health community is turning its attention to the effects of work on previously underserved populations, and researchers have identified many examples of disparities in occupational health outcomes. However, the occupational health status of some underserved worker populations is not described due to limitations in existing surveillance systems. As such, the occupational health community has identified the need to enhance and improve occupational health surveillance to describe the nature and extent of disparities in occupational illnesses and injuries (including fatalities), identify priorities for research and intervention, and evaluate trends. This report summarizes the data sources and methods discussed at an April 2008 workshop organized by NIOSH on the topic of improving surveillance for occupational health disparities. We discuss the capability of existing occupational health surveillance systems to document occupational health disparities and to provide surveillance data on minority and other underserved communities. Use of administrative data, secondary data analysis, and the development of targeted surveillance systems for occupational health surveillance are also discussed. Identifying and reducing occupational health disparities is one of NIOSH's priority areas under the National Occupational Research Agenda (NORA).

Abstract
OBJECTIVE Factors associated with private health insurance payment rates for musculoskeletal back disorders were examined among a 15-year cohort of union carpenters. Payment patterns were contrasted with work-related back injury rates over time. METHODS Negative binomial regression was used to assess payment rates; generalized estimated equations accounted for multiple observations per person and cost correlation within subjects. RESULTS Payment rates increased after work-related injury and with the number of injuries. Increasing private payments and deductibles (inflation-adjusted and discounted) were observed in contrast with a marked decline in reported work-related injuries. CONCLUSIONS Private insurance payments do not appear to be independent of work-related back injury. Findings suggest cost-shifting from workers' compensation to the union-provided health insurance and to the worker; they also provide a warning regarding reliance on workers' compensation statistics for surveillance of work-related disorders or disease.

Abstract
METHODS Union administrative records identified 20,642 union carpenters who worked in Washington State from 1989 to 2003. The Department of Labor and Industries provided records of workers' compensation claims and associated medical care. Work-related back claims (n = 4,241) were identified by ANSI codes (back, trunk, or neck/back) or ICD-9 codes relevant to medical care consistent with a back injury. Cases (n = 738) were defined as back injury claims with >90 days of paid lost time; controls (n = 699) resulted in return to work within 30 days. Logistic regression models estimated odds ratios and 95% confidence intervals (OR, 95% CI) of delayed return to work (DRTW). RESULTS Thirty percent of case claims and 8% of control claims were identified by an ICD-9 code. DRTW after back injury was associated with being female (2.7, 95% CI: 1.3-5.5), age 30-44 (1.2, 95% CI: 0.9-1.7) and age over 45 (1.6, 95% CI: 1.1-2.3), four or more years union experience (1.4, 95% CI: 1.1-1.8), previous paid time loss back claim (1.8, 95% CI: 1.3-2.5), and >or=30-day delay to medical care (3.6, 95% CI: 2.1, 6.1). Evidence of more acute trauma was also associated with DRTW. CONCLUSIONS Use of ICD-9 codes identified claims with multiple injuries that would otherwise not be captured by ANSI codes alone. Though carpenters of younger age and inexperience were at increased risk for a paid lost time back injury claim, older carpenters and more experienced workers, once injured, were more likely to have DRTW as were those who experienced acute events.

Abstract
BACKGROUND We measured resources used to provide medical care and to estimate lost productivity represented by payments for lost work time or impairment for work-related back injuries among a large cohort of union carpenters over 15 years. METHODS Using administrative data we identified a cohort of carpenters, their hours worked, their workers' compensation claims and associated costs. After adjustment for inflation and discounting to 2006 dollars, yearly costs for injuries and payment rates based on hours worked were calculated. Using negative binomial regression, dollars paid per claim were modeled based on age, gender, union tenure, and predominant type of work of the carpenter and whether the injury resulted from overexertion or acute trauma. RESULTS Workers' compensation costs for back injuries exceeded $128 million dollars between 1998 and 2003, representing payments of $0.97 for each hour of work. Costs per hour of work declined substantively over time due largely to declining overexertion injury rates. Traumatic injuries, though less common than overexertion injuries, were more expensive. Costs increased with the number of prior back injuries and with increasing age, beginning as early as age 30. CONCLUSIONS Increasing costs even among relatively young carpenters likely reflect the heavy nature of their work rather than simply the effects of biological aging. Musculoskeletal back problems remain a common, and consequently costly, source of injury among these carpenters that needs to be addressed through engineering modifications; there are also clearly needs for prevention of the often more costly back injuries associated with acute trauma.

Abstract
BACKGROUND Previous studies have reported that livestock-handling injuries are among the most severe of agricultural injuries. This study identifies the costs, characteristics, and contributing factors associated with livestock-handling injuries among Colorado dairy farmers, cattle/livestock raisers, and cattle dealers. METHODS A 10-year (1997-2006) history of Colorado's workers' compensation claims data was used for analysis. Descriptive analyses of livestock-handling injury claims were performed. Claim cost analysis was also conducted. The agent-host-environment epidemiological model was used to analyze injury event descriptions. RESULTS A total of 1,114 livestock-handling claims were analyzed. Claims associated with milking parlor tasks represented nearly 50% of injuries among dairy workers. Claims associated with riding horseback, sorting/penning cattle, and livestock-handling equipment represented high proportions of livestock-handling injuries among cattle/livestock raisers and cattle dealers. Claims associated with livestock-handling represented the highest percentage of high-cost and high-severity injuries in all three sectors. CONCLUSIONS Livestock-handling injuries are a significant problem, more costly, and result in more time off work than other causes of agricultural injuries. There is a strong and compelling need to develop cost-effective interventions to reduce the number of livestock-handling injuries in agriculture.

Abstract
The objective of the study was to determine if female workers in a heavy manufacturing environment have a higher risk of injury compared with males when performing the same job and to evaluate sex differences in type or severity of injury. By use of human resources and incident surveillance data for the hourly population at 6 US aluminum smelters, injuries that occurred from January 1, 1996, through December 21, 2005, were analyzed. Multivariate logistic regression, adjusted for job, tenure, and age category, was used to calculate odds ratios and 95% confidence intervals for female versus male injury risk for all injuries, recordable injuries, and lost work time injuries. The analysis was repeated for acute injuries and musculoskeletal disorder-related injuries separately. Female workers in this industry have a greater risk for sustaining all forms of injury after adjustment for age, tenure, and standardized job category (odds ratio = 1.365, 95% confidence interval: 1.290, 1.445). This excess risk for female workers persisted when injuries were dichotomized into acute injuries (odds ratio = 1.2) and musculoskeletal disorder-related injuries (odds ratio = 1.1). This study provides evidence of a sex disparity in occupational injury with female workers at higher risk compared with their male counterparts in a heavy manufacturing environment.

Abstract
BACKGROUND There is limited information on occupational back pain specific to carpenters despite their known exposures to recognized occupational risk factors and limited opportunities for modified work due to the predominantly heavy nature of their work. METHODS By combining union records with worker's compensation claims, we describe work-related back injuries, including associated medical diagnoses, among a well-defined cohort of union carpenters between 1989 and 2003. High risk subgroups were explored based on age, gender, union tenure, and predominant type of work. Paid lost time claims were contrasted to less serious events, and injuries sustained from overexertion activities were contrasted with those sustained through more acute trauma. RESULTS Back injuries occurred at an overall rate of 6.2/200,000 hours worked. Most injuries were coded in the compensation records as sprains, but there was little agreement between these nature of injury codes and ICD9 diagnosis codes. Injury rates declined most significantly over time for injuries secondary to overexertion. In multivariate analyses, we observed similar patterns of risk for the types of claims evaluated despite disparate mechanisms and severity. Those who worked predominantly in residential carpentry or drywall installation were consistently at greatest risk. CONCLUSIONS Overexertion injuries from manual materials handling activities are responsible for the largest burden of back injuries among these carpenters, but a growing proportion of injuries result from acute traumatic events. Interventions are called for which specifically address risk among residential carpenters and drywall installers. These data provide additional evidence that Bureau of Labor Statistics data underestimate work-related injuries.

Abstract
BACKGROUND Musculoskeletal disorders (MSD) are thought to be declining based on Bureau of Labor Statistics survey data, but there is also evidence of MSD under-reporting, raising the possibility of contrary trends. The magnitude of MSD under-reporting over time, and its industry distribution have not been adequately described. METHODS Capture-recapture analysis of 7 years of Connecticut MSD (1995-2001), utilizing Workers' Compensation and physician reporting data was performed. RESULTS Only 5.5%-7.9% of MSD cases appear to be reported to Workers Compensation annually. The capture-recapture estimated average annual rate for upper-extremity MSD was 133.1 per 10,000 employed persons, far above BLS rates. By industry, Manufacturing, State Government, and the Finance/Insurance/Real Estate sectors all had significantly higher MSD rates than Wholesale/Retail Trade. CONCLUSIONS Upper-extremity MSD appears to be significantly under-reported, and rates are not decreasing over time. Capture-recapture methods provide an improved surveillance method for monitoring temporal trends in injury rates.

Abstract
This study estimated injury and illness rates, risk factors, and costs associated with construction work in Oregon from 1990-1997 using all accepted workers' compensation claims by Oregon construction employees (N = 20,680). Claim rates and risk estimates were estimated using a baseline calculated from Current Population Survey data of the Oregon workforce. The average annual rate of lost-time claims was 3.5 per 100 workers. More than 50% of claims were by workers under 35 years and with less than 1 year of tenure. The majority of claimants (96.1%) were male. There were 52 total fatalities reported over the period examined, representing an average annual death rate of 8.5 per 100,000 construction workers. Average claim cost was $10,084 and mean indemnity time was 57.3 days. Structural metal workers had the highest average days of indemnity of all workers (72. 1), highest average costs per claim ($16,472), and highest odds ratio of injury of all occupations examined. Sprains were the most frequently reported injury type, constituting 46.4% of all claims. The greatest accident risk occurred during the third hour of work. Training interventions should be extensively utilized for inexperienced workers, and prework exercises could potentially reduce injury frequency and severity.

Abstract
A cohort of 13,354 male union carpenters in New Jersey was linked to cancer registry data to investigate cancer incidence during 1979 through 2000. Surveillance, Epidemiology and End Results data were used to calculate standardized incidence ratios (SIRs). A total of 592 incident cancers were observed among this cohort (SIR=1.07), which was not statistically in excess. However, significant excesses were observed for cancers of the digestive system and peritoneum (SIR=1.24) and the respiratory system (SIR=1.52). Workers in the union more than 30 years were at significant risk for cancers of the digestive organs and peritoneum (SIR=3.98), rectum (SIR=4.85), trachea, bronchus, and lung (SIR=4.56), and other parts of the respiratory system (SIR=11.00). Testicular cancer was significantly in excess (SIR=2.48) in analyses that lagged results 15 years from initial union membership. Additional etiologic research is needed to evaluate possible occupational and nonoccupational risk factors for testicular cancer.

Abstract
BACKGROUND Falls are a leading cause of morbidity and mortality in the construction trades. METHODS We identified a cohort of 16,215 active union carpenters, hours worked, and their workers' compensation claims for a 10-year period. The data on this well-defined cohort were used to describe their work-related falls; to define rates of injury and the associated costs; and to identify high-risk groups. RESULTS Same level falls occurred at a rate of 1.8/200,000 hours worked; falls from elevations at a rate of 2.3/200,000 hours worked. These injuries resulted in direct payments of 0.30 dollars per hour of work or 2.40 dollars per 8-hr day. Mean costs per fall increased with increasing age. Age was not associated with risk of falls from elevations; younger carpenters had modestly reduced rates of falls from the same level. Rates of falls decreased with increasing time in the union. Carpenters whose usual work involved drywall installation or residential work were at highest risk. CONCLUSIONS Falls are a significant public health risk for carpenters and they are responsible for a significant burden of work-related injury costs. While there is a need for prevention of falls from elevations--through training, enforcement of fall protection regulations, improved safety climate, or engineering changes--there is also the need to prevent falls from lower elevations. Differences in risk likely reflect varying exposures and safety practices in different areas of carpentry, as well as training, experience, and job assignments based on longevity in the union.

Abstract
BACKGROUND Washington State enacted a change in their fall standard for the construction industry in 1991, preceding the Safety Standard for Fall Protection in the Construction Industry promulgated by Federal OSHA in 1994. METHODS We evaluated changes in the rate of falls from elevations and measures of severity among a large cohort of union carpenters after the fall standard change in Washington State, taking into account the temporal trends in their overall injury rates. RESULTS There was a significant decrease in the rate of falls from height after the standard went into effect, even after adjusting for the overall decrease in work-related injuries among this cohort. Much of the decrease was immediate, likely representing the publicity surrounding fatal falls and subsequent promulgation of the standard. The greatest decrease was seen between 3 and 3(1/2) years after the standard went into effect. There was a significant reduction in mean paid lost days per event after the standard change and there was a significant reduction in mean cost per fall when adjusting for age and the temporal trend for costs among non-fall injuries. CONCLUSIONS Through the use of observational methods we have demonstrated significant effects of the Washington State Vertical Fall Arrest Standard among carpenters in the absence of a control or comparison group. Without controlling for the temporal trend in overall injury rates, the rate of decline in falls appeared significantly greater, but the more pronounced, but delayed, decline was not seen. The analyses demonstrate potential error in failing to account for temporal patterns or assuming that a decline after an intervention is related to the intervention.

Abstract
Findings are reported on the first two years of an active injury surveillance project designed to test the utility of active injury investigations in identifying causes of injury among a large cohort of carpenters who did residential building and drywall installation. Occupational Safety and Health Administration recordable injuries were reported by participating contractors. Injured union carpenters were interviewed by experienced journeymen trained in a standard questionnaire protocol. Enumeration of workers and hours worked were provided by the union. These data allowed the definition of a dynamic cohort of 4429 carpenters, their hours worked, detailed information on the circumstances surrounding recordable injuries, and possible preventive measures from the perspectives of the injured worker and an experienced journeyman investigator. The overall estimated injury rate (16.9 per 200,000 hours worked) was considerably higher than recent Bureau of Labor Statistics rates despite less than complete ascertainment of injuries. Injuries most commonly involved being struck by or against something, manual materials handling injuries, and falls. Manual materials handling injuries often involved very heavy objects or tasks and were injuries carpenters most often reported needs for adequate help and coordinated team work to prevent. Falls from heights occurred from a variety of surfaces and were not just injuries of inexperience. Carpenters reported the need for more attention to common fall protection practices, such as the use of more toe boards and guardrails. Poor housekeeping was involved in the majority of same level falls, as well as some manual materials handling injuries.

Abstract
BACKGROUND Persons in the construction trades in the US have high rates of alcohol and substance abuse. We had the unique opportunity to evaluate health care utilization through private insurance and workers' compensation for a group of carpenters at high risk of injury and substance abuse. METHODS We identified a cohort of union carpenters. Their claims for medical care through union insurance and workers' compensation, and appropriate measures of time at risk were documented. Using methods of indirect standardization, we compared utilization and costs between carpenters with and without alcohol and substance-abuse related diagnoses (ASRD). RESULTS Through private insurance, those with ASRD had 10% higher outpatient utilization and 2.1 times higher rates of hospitalizations for injury care; 2.6 times higher rates of outpatient care; and 2.9 times higher inpatient admissions for non-injury care. Individuals with ASRD had only modestly increased rates (10%) of outpatient utilization through workers' compensation. CONCLUSIONS These findings support the need for alcohol and drug abuse prevention and treatment services for this workforce. Operationalizing this among highly mobile workforces, such as the construction trades, is a challenge. While not intending to minimize the problems of alcohol or substance abuse on the job among carpenters, the focus of prevention should not necessarily be in the workplace.

Abstract
The first step in addressing any problem is recognition of the problem and a measure of its size and scope. There have been few reviews to date of the evidence of a musculoskeletal disorders problem in construction, particularly in the United States. Construction contractors in the United States have questioned the existence of a musculoskeletal disorders problem in construction, so a review of the evidence is warranted. The types of evidence reviewed include: 1) historical evidence, 2) injury data, 3) workers' compensation data, 4) medical exam data, 5) survey data, and 6) exposure data. Injury data generally represent injuries that the employers have identified as work-related and recorded or reported. Workers' compensation data are from cases that have been filed by workers for compensation and quite often represent only "closed" cases where compensation has been awarded. Medical exam data are from physical examinations of workers. Symptom survey data are the most inclusive and show the number of workers who self-report musculoskeletal problems. Exposure data include measurements made of exposure to musculoskeletal risk factors. The existing data show construction workers to be at significant risk of musculoskeletal injury, specifically related to the work they do. Their risk of musculoskeletal injury is much higher than that of other workers who have less heavy work, about 50 percent higher than all other workers. Several trades have been extensively studied, while others have been studied to a lesser extent. While the exact relationship between exposures and injuries is complex and often multifaceted, it would be difficult to deny the existence of the problem and the fact that these injuries are, to a great extent, related to the work that construction workers perform.

Abstract
Using a surveillance system that captures data on construction workers treated in an urban emergency department, we identified a series of injuries caused by vessels and tools under air pressure. We describe those six cases, as well as similar cases found in the Census of Fatal Occupational Injuries; we also review data from the National Surveillance for Traumatic Occupational Fatalities database and data from the Bureau of Labor Statistics. Among the injuries and deaths for which we had good case descriptions, the majority would have been prevented by adherence to existing Occupational Safety and Health Administration standards in the construction industry.
