A major survey of French workplaces has revealed few workers are adequately protected from the risks posed by carcinogenic, mutagenic or reprotoxic substances (CMR agents) – in general, substances that carry a cancer or reproductive health risk. Inspections at 2,000 firms found only 40 per cent of workplaces using CMR agents – nearly half of all the firms visited were using these substances – had carried out the necessary risk assessment.
