Mexican Chemical Contaminants in the Work Environment——Recognition, Evaluation and Control-Exposure Limit Values for Chemical Contaminants in the Work Environment(NOM-010-STPS-2014)

Mexican Chemical Contaminants in the Work Environment——Recognition, Evaluation and Control-Exposure Limit Values for Chemical Contaminants in the Work Environment(NOM-010-STPS-2014) is a mandatory legal limit enforced by the Mexican Ministry of Labor. This list includes hundreds of chemical substances, specifying detailed 8-hour TWA and 15-minute STEL limits for each. Solvents with respiratory irritancy and neurotoxicity constitute the highest proportion in industrial hygiene compliance inspections. The standard explicitly requires enterprises to post limit notices in workplaces and regularly update hazard communication plans.
