NIOSH has proposed an IDLH for Peracetic acid of 0.55 ppm, but is seeking more information from the industry before finalizing the level. NIOSH intends to evaluate the scientific data on peracetic acid (CAS#79-21-0) and develop appropriate communication products that convey the potential health risks, recommended measures for safe handling, and establish exposure recommendations including a Recommended Exposure Limit (REL) and an immediately dangerous to life or health (IDLH) value.
On March 7, 2017, NIOSH published a request for information on the following topics related to health risks to workers associated with occupational exposures to PAA:
- Workplace exposure data;
- Possible health effects observed in workers;
- Workplaces and products where PAA may be found;
- Work tasks and scenarios with a potential for exposure;
- Reports and findings from in vitro and in vivo toxicity studies;
- Data for the quantitative risk assessment of health effects associated with workplace exposure;
- PAA sampling and analytical methods; and
- Control measures used in workplace.
Comments are due by June 5, 2017.
