Under 29 CFR 1904.40, when an OSHA representative requests records, the employer must provide copies of the OSHA 300, 300A, and 301 forms by the end of the next business day — commonly interpreted as within 4 business hours during an on-site inspection.
Q5A supervisor discovers that a subcontractor on a multi-employer worksite has created an electrical hazard that could expose employees of other trades to harm. Under OSHA's multi-employer worksite policy, which party can OSHA cite for that hazard?
Show answer
✓ Correct answer: The creating employer, and potentially the controlling and exposing employers
OSHA's multi-employer citation policy allows the agency to cite the creating, exposing, correcting, and/or controlling employer depending on each party's role and knowledge of the hazard.
Q6After receiving an OSHA citation, an employer who disagrees with the finding must contest it within how many working days of receiving the citation?
Show answer
