NIOSH Draft Immediately Dangerous to Life or Health (IDLH) Value Profile for Peracetic Acid (CAS #79-21-0)

On May 1, 2015, the Director of the National Institute for Occupational Safety and Health (NIOSH) of the Centers for Disease Control and Prevention (CDC), published a notice in the Federal Register [80 FR 24930] announcing the availability of and a request for comments for the draft immediately dangerous to life or health (IDLH) values and support technical documents, entitled IDLH Values Profiles, for 14 chemicals. Written comments were to be received before the end of the comment period on June 30, 2015. Due to subsequent requests from the public, NIOSH announced in the Federal Register [81 FR 53147] the reopening of the review period of the draft IDLH Value Profile for peracetic acid (CAS #79-21-0) for an additional 60 days.

The proposed IDLH value and draft IDLH Value Profile for peracetic acid is based on the process outlined in the NIOSH Current Intelligence Bulletin 66—Derivation of Immediately Dangerous to Life or Health (IDLH) Values. The draft IDLH Value Profile was developed to provide the scientific rationale behind the derivation of the proposed IDLH value for peracetic acid. This includes a detailed summary of the health hazards of acute exposure to high airborne concentrations of peracetic acid and the rationale for the proposed IDLH value for peracetic acid.

To facilitate the review of this draft document, NIOSH requested that the following questions be taken into consideration:

1. Does this document clearly outline the health hazards associated with acute (or short-term) exposures to the peracetic acid? If not, what specific information is missing from the document?
2. Are the rationale and logic behind the derivation of an IDLH value for peracetic acid clearly explained? If not, what specific information is needed to clarify the basis of the IDLH value?
3. Are the conclusions supported by the data?
4. Are the tables clear and appropriate?
5. Is the document organized appropriately? If not, what improvements are needed?
6. Are you aware of any scientific data reported in governmental publications, databases, peer-reviewed journals, or other sources that should be included within this document?
