Personal Protective Equipment: Selection, Inspection, and Care

Why PPE Is Your Last Line of Defense

Engineering controls—ventilation, welding curtains, machine guards—reduce hazards at the source. Personal protective equipment (PPE) protects you when those controls are not enough. In welding and cutting, hazards arrive simultaneously: intense ultraviolet (UV) and infrared (IR) radiation, spatter and sparks, toxic fumes, noise, and crushing or puncture risks to the feet. Selecting the wrong PPE, or wearing damaged PPE, is the same as wearing none at all.

Eye and Face Protection: Lens Shade Selection

The welding arc produces UV and IR radiation intense enough to cause arc eye (photokeratitis) and permanent retinal damage in seconds. Every welder must wear the correct filter lens shade for the process and amperage in use.

ANSI/ISEA Z87.1 establishes the performance standard for eye and face protection. OSHA's general-industry and construction standards reference recommended shade numbers. The following shades are widely accepted minimums:

• SMAW (Stick): Shade 10 for lower amperages; shade 11–12 for heavier electrodes and higher amperage.
• GMAW (MIG) and FCAW: Shade 10 is a common starting point; shade 11 for higher wire-feed speeds and amperage.
• GTAW (TIG): Shade 8–10 depending on amperage; TIG arcs are less intense but still hazardous.
• Plasma cutting: Shade 8–9 for lower current; shade 10 or higher for higher current and thicker material.

When in doubt, start with a darker shade and work lighter until you can see the weld puddle clearly without straining—never compromise eye safety for visibility.

Auto-darkening helmets switch from a light state (typically shade 3–4) to the welding shade in milliseconds. Inspect them before every shift: check the solar-assist or battery indicator, test the switching speed by striking an arc on scrap, and verify the lens is free of cracks or pitting. Passive helmets use a fixed filter lens; ensure the shade number is marked on the lens and the lens is seated correctly in the shell.

Always wear safety glasses (Z87.1-rated) under the welding helmet. When you flip the helmet up, sparks and slag chips are still present.

Flame-Resistant Clothing

Synthetic fabrics melt onto skin. Cotton and wool are acceptable only if treated or certified as flame-resistant (FR). Dedicated FR garments carry a label stating the fabric standard they meet. Key rules:

• Wear long sleeves; roll them down and button cuffs.
• Do not wear FR clothing that is torn, contaminated with grease or flammable solvents, or has been washed with fabric softener (softener degrades FR properties).
• Leather welding jackets or sleeves provide additional protection for out-of-position work where spatter exposure is high.
• Avoid clothing with open pockets facing upward—sparks accumulate there.

Hand Protection

Heavy leather welding gloves (gauntlet style) are required for SMAW, GMAW, and FCAW. Inspect for holes, burns, or stiffening from heat damage. A hole in the palm over a hot workpiece is a serious burn risk.

TIG gloves are thinner leather or heat-resistant fabric, allowing the finger dexterity GTAW demands. They offer less spatter protection, so they are not appropriate for stick or MIG welding.

Plasma cutting gloves should be heavy leather—cutting spatter is extremely hot.

Foot Protection

Steel-toed, leather boots rated to ASTM F2413 standards protect against dropped materials and rolling objects. Leather uppers resist spark and spatter ignition. Do not wear boots with nylon or mesh panels—spatter burns through them. Pant legs should cover the boot top to prevent spatter collection inside the boot shaft. Never wear open-toe footwear in the shop.

Respiratory Protection

Welding fumes contain metal oxides and, depending on base metal and coatings, potentially hexavalent chromium, manganese, or zinc (from galvanized steel). OSHA permissible exposure limits (PELs) apply; ventilation is the primary control. When ventilation is inadequate—confined spaces, low-ventilation shops, or coated/stainless materials—a half-face air-purifying respirator with the correct cartridge type (typically combination particulate/organic vapor, verified for the specific contaminants) is required. Consult your employer's written respiratory protection program and your Safety Data Sheets. A respirator must be fit-tested, and the wearer must be medically cleared before use. Inspect the face-piece for cracks, check cartridge expiration dates, and perform a user seal check every time you don the respirator.

Hearing Protection

Grinding, chipping slag, and compressed-air tools can exceed 90 dB. Foam earplugs or earmuff-style hearing protectors must be used when noise levels warrant. Insert earplugs fully; inspect earmuff cushions for cracks that break the acoustic seal.

Donning and Doffing Correctly

Donning order (put on): Safety glasses → FR clothing and boots (already on) → gloves → helmet. For respiratory work: respirator → glasses → helmet.

Doffing order (remove): Remove helmet first (outer contamination stays outward) → gloves (fold cuff outward, pull off without touching the outer surface) → respiratory protection → safety glasses last.

Never lay a welding helmet lens-down on the bench—the lens scratches, reducing visibility and potentially compromising shade integrity.

Pre-Use Inspection Checklist Summary

1. Helmet: Shell intact, no cracks; lens shade correct and marked; auto-darkening battery/function tested; headgear adjusts and locks.

2. Safety glasses: Z87.1 marking present; lenses unscratched; temples and nose bridge intact.

3. FR clothing: No tears, no contamination, no missing buttons at cuff.

4. Gloves: No holes, burns, or wet spots; seams intact.

5. Boots: Steel toe cap not exposed; no mesh panels; laces secure.

6. Respirator: Cartridges not expired; no face-piece cracks; seal check passed.

7. Hearing protection: Plugs soft and pliable; earmuff cushions uncracked.

Reject any item that fails inspection. Tag it out and replace it before you begin work.
