[Guides to chemical risk assessment in the construction industry]

The presence of chemical agents in construction is certainly relevant in terms of quality, quantity and toxicity. Their manipulation can result in potential exposure as inhaled and/or through the skin. It is therefore possible and necessary to identify a list of substances to be considered relevant for the risk assessment and the possible environmental monitoring to verify the adequacy of the estimate made. The many variables inherent in construction make it extremely difficult to apply the usual methods of the industrial hygiene because it would not very significant conclusions in terms of space-time representation. SIMLII in one of its guidelines have proposed a "indexes" method that can provide useful information to the figures of prevention for the actions of their competence. The subsequent introduction of the REACH Regulation and exposure scenarios may help to further sharpening the assessment of chemical hazards in construction.
