Stronger breathing protections for workers
If you work with acrylonitrile, the rule aligns the chemical standard with OSHA’s Respiratory Protection standard so workplaces have clearer rules to protect workers’ lungs. The change is meant to make breathing safety requirements more consistent and reduce lung hazards for employees who handle this chemical.
Designed to avoid big costs or delays
OSHA says the revisions are intended to keep workplaces safer without causing big costs or delays for employers who use acrylonitrile. That means businesses should be able to follow the updated respiratory-aligned rules without major new expenses or long implementation waits.
