Employers must keep 1,3‑Butadiene records

Employers covered by the 1,3‑Butadiene standard must continue monitoring worker exposure, maintain compliance and exposure‑goal programs when exposures exceed limits, label respirator filter elements with the date/time first installed, and keep related records. OSHA says the total estimated burden remains 887 hours, affecting 57 respondents with 3,610 responses and estimated operation and maintenance costs of $103,550.

Workers get medical surveillance and exposure info

The standard requires employers to establish medical surveillance programs to monitor employee health and to provide employees information about their exposures and the health effects of 1,3‑Butadiene. These protections apply where employee exposures meet the standard's triggers.
