RESUMO
European directives stipulate that French employers take all available measures to reduce the use of carcinogenic agents. Our study explores the links between regulations on chemicals and the effective implementation of collective protection measures in France to occupational exposure to carcinogenic chemicals. Individual data from the French national cross-sectional survey of occupational hazards, conducted in 2017, were analysed. We investigated whether stricter regulations and longer exposures were associated with a higher level of collective protection using multivariate logistic regressions. In 2017, any collective protection measures were implemented for 35% of occupational situations involving exposure to a carcinogen. A total of 21% of exposure situations benefited from source-based controls (e.g., isolation chamber and local exhaust ventilation) and 26% from general ventilation, for which the effect is limited as collective protection. Our regressions showed that longer exposure durations were associated with more collective protection. Exposure situations to chemicals classified as proven carcinogens by the European Union (category 1A) benefited more from collective protections, which is not the case for products only classified as suspected carcinogens (category 1B). Exposures to products with a Binding Occupational Exposure Limit Value benefited more from source-based controls. Nonetheless, the time spent on the IARC list of carcinogens did not appear to influence the implementation of collective protection measures, except for local exhaust ventilation. At a time when efforts to improve the implementation of protective measures in order to drastically reduce the risks of occupational cancers are still necessary, stricter European and national regulations, but above all, better coordination with the work of the IARC and its classification, are avenues to pursue.

Background: Our study examined the social disparities that exist in the implementation of protection measures for occupational exposure to carcinogenic, mutagenic and reprotoxic agents in France, and its aim was to identify which types of employees/jobs require priority action. Methods: We analyzed data from the 2010 French national cross-sectional survey of occupational hazards. The availability of the various collective and individual protections was explored. The associations of job and company characteristics with protective measures were studied by multilevel regressions. Results: Effective collective protection measures were implemented in 25% of the exposure situations. Managers and intellectual professionals, who accumulated lower CMR exposure prevalences, durations, and intensities than blue-collar workers, benefited the most from effective collective protections. The availability of effective collective protection measures was not influenced by the size of the company. The presence of a Committee for health, safety, and work conditions, as well as intervention of occupational health and safety officers in the past 12 months were associated with a lower exposure intensity, but not with the implementation of more protection measures. Longer exposure durations were associated with more effective collective protection. Conclusion: Substantial discrepancies were observed in exposure levels and protection measures as a function of the characteristics of employees' jobs and the companies that they work for. The main priority in regard to prevention should be a focus on unskilled workers, since their collective protection still appears to be insufficient, while their exposure lengths and intensities were the most substantial.

Background: To explore trends in social and occupational inequalities in terms of exposure to carcinogenic, mutagenic and reprotoxic chemicals (CMR) for French employees. Our study assessed data from the French national cross-sectional survey of occupational hazards (SUMER) that was conducted in 2003 and 2010. We included all of the 27 CMR agents that were classified by the International Agency for Research on Cancer or European Union regulations as being known or presumed to have CMR potential in humans. Trends in prevalence and degree of exposure were examined using multilevel logistic regression analysis. The number of employees exposed to CMR agents decreased by 17.5% between 2003 and 2010. The only CMR entities for which exposure rates increased are not considered to be proven CMRs according to the European Union regulations. With the exception of apprentices, there was an overall decrease in exposure prevalence for all employees. This decrease occurred, however, to different extents. The decrease in the risk of exposure to CMR agents was much greater for those on permanent contracts, managers, and in enterprises with more than 500 employees. Nonetheless, in situations where there was potential for exposure, companies with fewer than 10 employees were in fact able to decrease the degree of risk more than the others. Our results confirm the relevance of reinforcing regulatory restrictions for CMR products, while also indicating that monitoring of trends in disparities will allow public health policy makers to better evaluate progress made toward reducing disparities that affect vulnerable populations.

PURPOSE: To explore varied exposure to carcinogenic, mutagenic, and reprotoxic chemicals (CMR) for French employees. METHODS: Our study assessed data from the French national cross-sectional survey of occupational risks (SUMER) that was conducted in 2010 in a national representative sample of employees. We selected 28 CMR agents that were classified by the International Agency for Research on Cancer or European Union as being known or presumed to have CMR potential in humans. The association of individual and job characteristics with exposure prevalence, duration, and intensity of the CMR agents during a 1-week period was examined using multilevel logistic regression analysis. RESULTS: Overall, 10.4% of employees in 2010 were exposed to one or more CMR agents at their workplace, and 3.4% were subjected to multiple CMR exposures. Blue-collar workers, night-shift workers and workers with short-term employment contracts experienced higher exposure prevalence (p < 0.01) and intensity (p < 0.05). Blue-collar workers and shift workers experienced also longer exposure duration (p < 0.001). Conversely, managers, workers of large companies, and women were less exposed to CMR agents (p < 0.001). The presence of a Committee for Health, Safety, and Working Conditions, and intervention by Occupational Health and Safety officers were significantly associated with reduced exposure intensities (p < 0.001 and p < 0.05). Establishment of European CMR regulations and the existence of an applicable substitution principle reduced the exposure duration (p < 0.001) and intensity (p < 0.05). CONCLUSIONS: Our results point out disparities in CMR exposure and identify high-priority targets for prevention measures to help reducing social health discrepancies.
