ObjectivesHydrogen peroxide (HP) accounts for 15% of the total global chemical revenue. According to the National Institute of Occupational Safety and Health, the HP concentration immediately dangerous to human life or health is 75 ppm. Operators exposed to HP should pay attention when choosing the monitoring technique that should be specific and sensitive enough to discriminate the exposure levels from background concentrations. In order to assess the long- and short-term exposure to HP in disinfection processes, the authors compared 6 industrial hygiene monitoring methods to evaluate their efficiency in measuring airborne HP concentrations.Material and MethodsAirborne HP concentrations were evaluated using an on-fiber triphenylphosphine solid-phase microextraction method, and they were compared with those obtained using a 13-mm Swinnex titanium oxysulfate filter holder and 4 portable direct-reading electrochemical sensors. A survey carried out in wood pulp bleaching, food and beverage disinfection processing, and in a hospital department to reduce the risk of spreading nosocomial infections, was performed during routine operations to access the risk of HP occupational exposure.ResultsThrough the generation of HP gaseous dynamic atmospheres (0.1–85 ppm), the authors evaluated the consistency of the results obtained using the 6 methods described. The monitoring campaigns showed that the increase in HP could be relatively high (until 67 ppm) in food and beverage processing.ConclusionsIn the authors’ opinion, the current 8-h time-weighted average limits of 1 ppm for HP do not reflect the actual risk; a short-term exposure limit would, therefore, provide a much better protection.
