OSHA’s general industry regulations on machine guarding or hand and portable power tools do not specifically prohibit employees from wearing jewelry or loose clothing. In the general industry electrical standards, §1910.333 is on selection and use of work practices. Paragraph (c) is on working on or near exposed energized parts. Section (c)(8) states: “Conductive articles of jewelry and clothing (such as watch bands, bracelets, rings, key chains, necklaces, metalized aprons, cloth with conductive thread, or metal headgear) may not be worn if they might contact exposed energized parts. However, such articles may be worn if they are rendered nonconductive by covering, wrapping, or other insulating means.” In the Powered Industrial Truck regulation (§1910.178), paragraph (g) is on changing and charging storage batteries. Section (g)(12) states that “Tools and other metallic objects shall be kept away from the top of uncovered batteries.” OSHA has published a booklet, Hand and Power Tools
