Difficulty: EasyPersonal Protective Equipment (PPE)

A technician is preparing to sharpen a cold chisel using a high-speed bench grinder. Because grinding wheels can fracture and generate high-velocity sparks and debris, which piece of personal protective equipment should be worn over approved safety glasses to protect the entire face?

  1. A clear full-face shieldAnswer
  2. B
    Standard everyday prescription eyeglasses
  3. C
    A dark-tinted arc-welding helmet
  4. D
    A disposable particulate dust mask

Answer

A clear full-face shield
A clear full-face shield worn over impact-resistant safety glasses provides necessary secondary protection for the entire face against high-speed sparks and flying fragments without restricting visibility.

Step-by-Step Solution

1
Identify the primary shop hazard present in the scenario
Bench grinding produces high-velocity sparks, metal filings, and potential wheel fragmentation hazards directed toward the technician's face.
Selecting the correct PPE requires determining the specific mechanical hazard involved.
2
Select the appropriate personal protective equipment that provides complete facial coverage over primary eye protection
A clear full-face shield worn in combination with safety glasses provides both primary eye and secondary whole-face impact protection.
Safety glasses alone only cover the immediate eye area; a full-face shield covers the entire facial area while maintaining clear visibility.
