2.Operator Protective Equipment
Personal protective equipment helps make tire servicing safer. However, equipment does not take the
place of safe operating practices. Always wear durable work clothing during tire service activity. Loose fit-
ting clothing should be avoided. Tight fitting leather gloves are recommended to protect operator’s hands
when handling worn tires and wheels. Sturdy leather work shoes with steel toes and oil resistant soles
should be used by tire service personnel to help prevent injury in typical shop activities. Eye protection is
essential during tire service activity. Safety glasses with side shields, goggles, or face shields are accept-
able. Back belts provide support during lifting activities and are also helpful in providing operator protec-
tion. Consideration should also be given to the use of hearing protection if tire service activity is performed
in an enclosed area, or if noise levels are high.
