Personal protective equipment (PPE) is the last line of defense between a metalworker and the hazards of the shop. This overview covers the core items — eye, hearing, hand, and respiratory protection, plus protective clothing — with conservative notes on when certain gear should not be worn.
Eye Protection
Always wear safety glasses or goggles when working in a metal shop to protect your eyes from sparks, debris, and chemicals. Choose glasses with side shields for additional protection against flying particles. For operations that produce intense light, such as welding, use eye protection with the appropriate filter shade for the process.
Hearing Protection
Noise levels can be high in metal shops, and hearing loss develops gradually and permanently. Use hearing protection such as earplugs or earmuffs to reduce the risk of noise-induced hearing loss. Some activities may call for specialized protection, such as earmuffs with communication capability.
Gloves — and When Not to Wear Them
Gloves protect your hands from cuts, burns, and chemicals. However, gloves must never be worn near rotating equipment, where they can be caught and pull the hand into the machinery.
- Wear Gloves: For handling stock, chemicals, and hot or sharp parts.
- Remove Gloves: Before operating rotating equipment such as drill presses, lathes, and bench grinders.
Always check the safety guidelines for the specific task and equipment.
Respiratory Protection for Dust and Fumes
Dust and fumes are common in metal shops. Use a dust mask or respirator for protection against inhalation hazards. For environments with significant levels of vapors or gases, consult a professional to choose the appropriate respiratory protection, and ensure the workspace is ventilated.
Protective Clothing
Protective clothing, such as aprons and coveralls, protects skin from chemicals and heat. Choose clothing that fits properly, does not impede movement, and cannot become caught in machinery. For welding and hot work, fire-resistant materials are standard.
The General Rule
Always follow the safety guidelines in equipment manuals, applicable codes, and the advice of qualified professionals when selecting and using personal protective equipment. PPE reduces risk; it does not remove it, and it is no substitute for safe work practices.
