23 Laboratory Safety Manual Environmental Health and Safety All PPE shall be thoroughly inspected for damage or worn parts before use, cleaned and sanitized after use if reusable, and properly stored away from sources of heat, sunlight, chemicals, or contamination. Single use PPE must be properly disposed of after each use or contact with contaminants has occurred. Remove all PPE before leaving the laboratory. PPE is available for purchase at Central Stores, 192 General Services Building / 700 Wallace Road, (515) 294-0408, or Chemistry Stores, 1400 Gilman Hall / 2415 Osborn Drive, (515) 294-0203. Laundry service for contaminated laboratory coats is available through Chemistry Stores. Contaminated PPE must NOT be taken home for laundering. Commonly used PPE Body Protection Body protection must be worn to protect skin exposure to harmful contaminants (for example: dusts, fogs, fumes, gases, mists, smokes, sprays, splashes, or vapors), limit contamination of “street clothing,” and aid the decontamination process. Lab coats shall constitute minimum body protection when working in laboratories. Elastomeric equipment (such as acid-resistant aprons) used for chemical resistance must be constructed of elastomers resistant to the material used. Wearing shorts or short skirts in laboratories is strongly discouraged. The required laboratory coat or nonpermeable apron must cover the knees. Eye and Face Protection Eye and face protection with filtered lenses designed to protect against light radiation are required when working with lasers, UV lamps, welding, or other sources of light radiation. Select the appropriate lens shade or filter for the operation performed. Face Shields Face shields are required where there is potential face exposure to chemicals, projectiles, and UV sources. Use of a face shield is not a substitute for eye protection, and it may be necessary to provide both means of protection (for example, working with corrosive materials).
