SAFE PRACTICE


• Dust and particles from shakeout, shot blast, grinding and cleaning


• Noise • Airborne contaminants (silica, dust, metal particulate)


• Hazards associated with welding, cutting and scarfing (arc air) Te recommended basic (sec-


ondary) protection for all cleaning and finishing operations are long pants, safety toe footwear and safety glasses with side protection. Te guide does not take the place of OSHA and ANSI standards, MSDS recommendations or other PPE standards. Employers are required to provide and replace only PPE used to comply with regulations. Employ- ers cannot require workers to supply their own PPE, and if an employee chooses to do so, the employer must ensure the PPE is adequate protec- tion from hazards in the workplace. Based on the results of a hazard assessment (Fig. 1), some operations may require additional clothing and PPE beyond the basic protection. Review the results of industrial hy- giene monitoring of noise, dust, metal fumes, gases and vapors, and note the size, weight and configuration of castings as well as the alloy content. Additional, primary PPE might


include long-sleeve shirts, coveralls, welding apparel, gloves, hard hats, metatarsal safety shoes, ear protec- tion, dust sealed and/or impact resistant goggles, face shields and re- spiratory protection. Te AFS guide recommends consulting OSHA Standard 29 CFR 1910, ANSI Z87 and Z89, ASTM F 2412 and 2413, and NIOSH Certification 42 CFR 84. In addition to 100% cotton cloth- ing with sleeves to protect against hot surfaces, consider the need for dexterity and grip when operating equipment. Hand protection may provide a combination of cut and vi- bration protection or may be layered. Additional primary PPE includes hard hats, safety toe cap footwear, eye and face protection, and hearing pro- tection that provides sufficient noise


reduction for the exposure. According to AFS, respirator selection and use must be part of an effective respiratory


protection program, and an air-sup- plied hood or helmet also may protect against heat and eye hazards.
