STEEL TOE Safety Shoes and Boots - Protects the toe area against falling objects or heavy rolling objects with steel protective cap. In 1995 OSHA began enforcing a new standard for personnel protective equipment. As part of this standard, employers now require ANSI Z41 PT99 rated safety footwear (steel toe boots and shoes)in areas where employees are exposed to injury as a result of falling or rolling objects. All steel toe shoes meet or exceed ANSI Z41 PT99 I/75 C/75 standards.
