|Only a fraction of thousands of chemicals |
used today has been tested - and that
info is often outdated, experts say.
The first stage of this dialogue is a request for information on the management of hazardous chemical exposures in the workplace and strategies for updating permissible exposure limits.
OSHA's PELs, which are regulatory limits on the amount or concentration of a substance in the air, are intended to protect workers against the adverse health effects of exposure to hazardous substances.
Ninety-five percent of OSHA's current PELs, which cover fewer than 500 chemicals, have not been updated since their adoption in 1971.
The agency's current PELs cover only a small fraction of the tens of thousands of chemicals used in commerce, many of which are suspected of being harmful.
Substantial resources are required to issue new exposure limits or update existing workplace exposure limits, as courts have required complex analyses for each proposed PEL.
"Many of our chemical exposure standards are dangerously out of date and do not adequately protect workers," said Assistant Secretary of Labor for Occupational Safety and Health Dr. David Michaels.
"While we will continue to work on updating our workplace exposure limits, we are asking public health experts, chemical manufacturers, employers, unions and others committed to preventing workplace illnesses to help us identify new approaches to address chemical hazards."
OSHA is seeking public comment regarding current practices and future methods for updating PELs, as well as new strategies for better protecting workers from hazardous chemical exposures. Specifically, the agency requests suggestions on:
- Possible streamlined approaches for risk assessment and feasibility analyses and
- Alternative approaches for managing chemical exposures, including control banding, task-based approaches and informed substitution.
In the coming months, OSHA will announce additional ways for members of the public to participate in the conversation.
The comment period for the RFI lasts for 180 days. Instructions for submitting comments are available in the Federal Register, Docket No. OSHA-2012-0023.
