Peru Updates its Occupational Chemical Exposure Limits to Protect Worker Health

On October 25, 2024, the Ministry of Health (MINSA) of Peru issued Ministerial Resolution No. 733-2024/MINSA, introducing crucial updates to Annexes I, II, and III of the "Regulation on Permissible Exposure Limits for Chemical Agents in the Work Environment," initially established by Supreme Decree No. 015-2005-SA. The existing regulation (D.S. No. 015-2005-SA) outlines acceptable exposure limits to chemical agents in workplaces across Peru, ensuring workers are not exposed to harmful levels of hazardous or carcinogenic chemicals. The recent updates are in response to scientific and technological advancements and aim to enhance protections based on the latest health and safety research.

The updated annexes classify permissible exposure limits for various chemical agents to which workers may be exposed, prioritizing quantitative evaluation and control measures, especially for substances primarily absorbed through inhalation. The revisions include newly identified hazardous substances, refined exposure limits, and updated toxicity thresholds, aligning them with global standards.

The new permissible exposure limits will apply to all work environments where chemical or carcinogenic agents pose potential health and safety risks. This update obligates employers to adopt stricter control measures, implement adequate personal protective equipment (PPE), and ensure continuous monitoring of hazardous substances.
