Abstract Activity sectors as varied as indoor swimming pools and the ready-to-use fresh vegetable industry are faced with high employee exposures to nitrogen trichloride. The INRS has conducted numerous studies aimed at both characterizing the chemical risk to which workers in these sectors are exposed and proposing technical solutions for reducing pollution and controlling work atmosphere quality. Besides the analytical, toxicological and epidemiological aspects, this document describes technical prevention solutions that have been developed and adapted to activities that involve exposure to nitrogen trichloride. Based on the principle of nitrogen trichloride stripping, two pilot installations have been installed in an indoor swimming pool and in a ready-to-use fresh vegetable-processing plant. Measurements have been carried out to confirm the efficiency of these installations.
