What is the action level for lead in air?

• A. 10 Micrograms per cubic meter
• B. 15 Micrograms per cubic meter
• C. 30 Micrograms per cubic meter
• D. 60 Micrograms per cubic meter

Answer: (C)

In OSHA’s lead standard, the action level is the threshold that triggers the employer’s required program elements for managing exposure. For lead in workplace air, this action level is thirty micrograms per cubic meter, averaged over an eight-hour workday. When exposures are at or above this level, employers must implement exposure monitoring, provide worker training, offer medical surveillance where applicable, and keep required records. If exposures reach the permissible exposure limit—fifty micrograms per cubic meter—additional, more stringent controls apply. The other numbers don’t represent the regulatory trigger, so thirty micrograms per cubic meter is the correct action level.
