Permeation of gasoline, diesel, bioethanol (E85), and biodiesel (B20) fuels through six glove materials

Risks related to the domestic laundering of filling station attendant uniforms: advances and uncertainties

Gasoline is the most common transportation fuel in Brazil, with up to 1% of benzene. Benzene is a health-damaging organic solvent that is extensively used worldwide, being classified as a human carcinogen by the International Agency for Research on Cancer (Group 1). Many workers at filling stations are exposed to benzene, present in gasoline. The main routes of exposure and absorption of benzene are inhalation, oral, and dermal routes. The penetration and maintenance of benzene and other chemicals on personal protective equipment and clothing of workers who manipulate these solvents may increase their levels of exposure and offer risks to their family members, since contaminated clothing is laundered at their homes, which goes against legislative framework (Annex 2, Regulatory Standard No. 9). This way, the objective of this work was to discuss the importance of periodic changes and cleaning of filling station attendant uniforms performed by employers as preventive measures against the deterioration of the health of workers and their family members. We performed a narrative review; no systematic criteria were used in the search for national and international studies. After critical reading, we observed a lack of consistent data on this theme. Laundering of uniforms worn by filling station attendants should take place outside the domestic environment in order to protect the health of workers and their family members and avoid possible cross-contamination.

Glove permeation of chemicals: The state of the art of current practice-Part 2. Research emphases on high boiling point compounds and simulating the donned glove environment

This second part of the review of the 21^st century literature on glove permeation is divided into the following major themes; permeation data and mathematical models, exposure/risk assessment, and manufacturer data. The major issues in the literature were the demonstrations that increasing temperature and applying forces increased permeation; and that glove manufacturer data were sometimes not reproducible. Double gloving of disposable gloves was found to be effective in resisting chemical permeation for short periods of time. Harmonization of standards and commercial glove classifications were called for at conditions that were closer to the temperature and applied forces actually present in the workplace, including whole glove testing and quantitative rather than just qualitative criteria. More research was recommended in each section and subsection with particular emphasis on defining the efficiency of solid phase collection devices, and more data in areas like exposure to cosmetics, household products, liquid foods, drinks, and cleaning liquids. More research in exposure assessment for permeated chemicals with sensors on the inner glove surface and on the skin was called for. Finally, it was decided that the state of the art of current practice was in a situation that needed the permeation standards, research, and the permeation charts of glove manufacturers to be at conditions that better reflected those encountered by workers with donned gloves.
