HEALTH. The national Agency of sanitary security (Anses) has formulated several recommendations in the area of occupational exposure limit value substances that are carcinogenic, mutagenic and reprotoxic (CMR). Details.
The national Agency of sanitary security (Anses) has formulated several recommendations in terms of the limit value of occupational exposure to six chemical substances, some of which are used in particular in the construction sector. The notice issued by this organization are generally transcribed later in the regulations by the ministry of Labour.
– Trichloroethylene (degreasing of metal parts, formulation of adhesives, paints, varnishes, glues, etc.): recommendation of an OELS on 8 working hours (TWA-8h) of 40 mg.m-3 (instead of the value of 405 mg.m-3 fixed by a circular of 1983) Anses states that this is the OELS do not protect against carcinogenic effects of trichloroethylene, but it is “only a tool to limit the exposure levels at work places”. The Agency also recommends not to exceed a period of 15 minutes the concentration equal to 5 times that recommended for the TWA-8h.
– Di-n-butylphtalate (DnBP, manufacture of polymers for plastic materials, cleaning products in the manufacture of metal products, rubber…) : recommendation of a TWA-8h 2 mg.m-3 (instead of the value of 5 mg.m-3 fixed by a circular of 1987) in order to prevent the effects reprotoxic of this substance.Do not exceed over a period of 15 minutes the concentration equal to 5 times that recommended for the TWA-8h.
– Butylbenzyl-phthalate (BBzP, agent, plasticizing in the production of glues, paints and mastics, 90% in Europe used in the production of PVC and polymer, flooring, paint…) : recommendation of a TWA-8h 13 mg.m-3 (value is not existing currently) in order to prevent the effects reprotoxic of this substance ; do not exceed a period of 15 minutes the concentration equal to 5 times that recommended for the TWA-8h.
– N-butanol (solvent for paint, varnishes, resins and adhesives, rubber-based, solvent cleaning) : recommendation of a limit value short-term (AUSTRALIA-15min) 100 mg.m-3 (instead of the value of 150 mg.m-3 fixed by a circular of 1982) in order to prevent the effects of eye irritation.
“The Agency reminds that the substitution of carcinogens, mutagens and substances toxic for reproduction substances or processes less harmful is a priority for the prevention of chemical risk at workplaces in France”, one can read on the website of the organization.
How are fixed values-workplace exposure limit (WEL) ?
The establishment of OELS in France consists of three phases :
– A phase of independent science be entrusted to Anses ;
– Phase establishment of a regulatory project value binding limit or guideline by the ministry of labour ;
– A phase of social dialogue within the Council guidance on working conditions (Coct).
