The NIOSH/OSHA PEL analysis documents a 1 mg/m³ 8-hour limit for platinum metal and explains that the limit applies to platinum metal dust, while noting that heavy-metal dusts warrant tighter control than nuisance dusts.

The proposed PEL was 1 mg/m3, and this limit is established in the final rule. NIOSH agreed that this PEL is appropriate. The ACGIH has a limit of 1.0 mg/m3 TWA for platinum metal dust.

NIOSH states that finely divided platinum powder can be dangerous to handle and reports irritation of the skin and respiratory system and dermatitis.
