1988 OSHA PEL Project

OSHA formerly had an 8-hour TWA limit of 10 mg/m 3 for iron oxide fume. The ACGIH has established a limit of 5 mg/m 3, measured as iron, total particulate. The proposed PEL was 5 mg/m 3, and NIOSH (Ex. 8-47, Table N1) supported the proposed limit. However, the final rule retains OSHA''s former limit of 10 mg/m 3 for this substance.
