CHEMICALS WITH OSHA AIR SAMPLING REQUIREMENTS

NC State EH&S (Industrial Hygiene group) conducts exposure assessment surveys of work areas to review safe work practices, to assess the potential for chemical exposure, and to recommend corrective action. OSHA requirements include air sampling, medical surveillance, and special handling procedures for certain materials and circumstances. Any new use of any of the substances in the following list should be immediately added to your chemical inventory, a copy of your updated inventory submitted to EH&S (Att. Mahdi Fahim, Box 8007) and an e-mail submitted to Mahdi_Fahim@ncsu.edu. If you have not yet provided this notification for a listed material, please consider this as new use for reporting purposes and supply the requested information. This will permit the necessary interaction to determine if air sampling, medical surveillance, or other appropriate handling procedures are necessary consistent with federal requirements.

Asbestos - Asbestos containing materials may not be used at NC State University. Construction and maintenance jobs may involve the disturbance of existing asbestos-containing building materials.This work may only be performed by specially trained personnel. Air sampling requirements are based on type of work performed.

Lead - This covers metallic lead, all inorganic lead compounds, and organic lead soaps. Sampling requirements may also apply to construction/maintenance activities where lead is disturbed.
