Definition

Inspectors should have a respirator for the times when they must enter areas containing materials that may introduce particulates into the air that are potentially hazardous if inhaled. Dust masks are inadequate. Respirators must be equipped to filter out both particulates that represent biological hazards, such as viral, bacterial and fungal organisms, and hazards caused by material lodging in the respiratory system, as with asbestos and other carcinogens. Other particulates that are small enough to become airborne may not be carcinogens but may cause other types of respiratory illness. Gloves and safety glasses used when working around exposed electrical components are other common safety items.
