Testing the joint health and safety committee assessment tool in the education sector

Joint Health and Safety Committee (JHSC) effectiveness has been identified as an area of concern for Ontario's education sector. The JHSC Assessment Tool has been previously tested in hospitals with positive results. This study assessed the feasibility and usability of the JHSC Assessment Tool in the education sector. Members of multi-workplace JHSCs from Ontario school boards used the tool to assess their committees' effectiveness before, during and after a committee meeting with usability testing conducted pre and post meeting. Results suggested that the JHSC Assessment Tool was feasible to use during a regular JHSC meeting, groups were able to come to consensus on the majority of items, and usability scores were high overall. Participant feedback provided insight that informed the development of a version relevant to multi-workplace committees.

Health survey of employees regularly using 3D printers

Background

3D printers emit potentially hazardous ultrafine particles and volatile organic compounds. Workers using 3D printing technologies may be at risk of respiratory illness from occupational exposure.

Aims

To assess whether 3D printing is associated with health effects in occupational users.

Methods

This was a preliminary survey. Workers in 17 companies using 3D printing, including commercial prototyping businesses, educational institutions and public libraries, in the Greater Toronto Area, Canada, were asked to complete survey questionnaires concerning demographic, occupational and health information. Associations between self-reported health history variables and occupational characteristics were examined by chi-square and Fisher's exact tests.

Results

Among 46 surveyed workers, 27 (59% of participants) reported having respiratory symptoms at least once per week in the past year. Working more than 40 h per week with 3D printers was significantly associated with having been given a respiratory-related diagnosis (asthma or allergic rhinitis) (P < 0.05). We observed a wide variation in occupational hygiene practices in the 17 printing workplaces that we surveyed.

Conclusions

Our finding of frequently reported respiratory symptoms suggests a need for additional studies on exposed workers in this field.

Educational intervention among farmers in a community health care setting

BACKGROUND

Farmers are at increased risk of developing work-related respiratory diseases including asthma, but little is known about their occupational health and safety (OHS) knowledge and exposure prevention practices. Educational interventions may improve knowledge and practice related to prevention.

AIMS

To determine the feasibility of an educational intervention for farmers in a community health centre setting.

METHODS

This was a pilot study. Farmers were recruited by the community health centre and completed a questionnaire on symptoms, OHS knowledge and exposure prevention practices. The intervention group received education on work-related asthma and exposure control strategies, and was offered spirometry and respirator fit testing. All subjects were asked to repeat the questionnaire 6 months later.

RESULTS

There were 68 study participants of whom 38 formed the intervention group. At baseline, almost 60% of farmers reported having received OHS training and were familiar with material safety data sheets (MSDSs); fewer (approximately 40%) reported knowledge of OHS legislation and availability of MSDSs. Approximately, two-thirds of subjects reported using respiratory protection. The response rate for repeating the questionnaire was 76% in the intervention group and 77% in the controls. Among the intervention subjects, statistically significant increases were observed in reported safety training, familiarity and availability of MSDSs and knowledge of OHS legislation.

CONCLUSIONS

Gaps in OHS knowledge were observed. The educational intervention on OHS knowledge and exposure prevention practices in the community health centre setting was feasible. Larger, more-controlled studies should be undertaken as this study suggests a positive effect on OHS knowledge and prevention practices.

Workers with occupational contact dermatitis: workplace characteristics and prevention practices

BACKGROUND

There are many gaps in knowledge related to prevention practices in place for workers who subsequently develop occupational contact dermatitis (OCD).

AIMS

To describe the workplace characteristics and the prevention practices in workplaces where workers developed hand dermatitis.

METHODS

Consecutive cases of probable OCD were enrolled from a specialist occupational health clinic. At the time of the initial assessment, questionnaires were administered to collect information about clinical presentation, workplace characteristics and prevention practices at work.

RESULTS

100 workers with hand dermatitis were enrolled in the study and 78 were considered to have OCD. Two-thirds of these had had some occupational health and safety or Workplace Hazardous Materials Information System (WHMIS) training in their workplace, however, training related to glove use and skin care was less common. Unionized workers were more likely to have received training. Workers involved in wet work were less likely to report training.

CONCLUSIONS

These findings suggest that there are gaps in prevention programs for work-related skin disease. Research is needed on effective strategies that are sustainable in the workplace.

Occupational contact allergens: are they also associated with occupational asthma?

BACKGROUND

Workplace exposures that can potentially cause both allergic occupational contact dermatitis (AOCD) and occupational asthma (OA) are not clearly identified.

METHODS

Occupational contact allergens (OCAs) were identified using North American Contact Dermatitis Group (NACDG) data. Reference documents and systematic reviews were used to determine whether each OCA had been reported to potentially cause OA. The presence or absence of a sensitizer notation in occupational hygiene reference documents was also examined.

RESULTS

The 10 most common OCAs were: epoxy resin*, thiuram, carba mix, nickel sulfate*, cobalt chloride*, potassium dichromate*, glyceryl thioglycolate, p-phenylenediamine*, formaldehyde* and glutaraldehyde*. Seven (indicated by *) were determined to be possible causes of OA. Information on sensitizing potential from OH reference materials contained conflicting information.

CONCLUSIONS

Several common OCAs can also potentially cause OA. Inhalation and dermal exposures to these agents should be controlled and both OA and AOCD should be considered as possible health outcomes. Increased consistency in sensitizer notations is needed.
