Welding Shop Safety Guide

Loss Control Academy – Field Reference Card

How to Use: Look around the shop from a safe distance—never touch tools or gases. Use a flashlight to check for sparks or leaks. Ask the shop owner: “Last safety check? Fire extinguisher tags?” Mark High (gas leaks, no ventilation), Medium (clutter, old tags), or Low (clean, tagged, trained) risk. Welding causes about $500,000 injuries and 22 deaths each year in the United States (Occupational Safety and Health Administration 2024 data); sparks start 35% of shop fires (National Fire Protection Association). Average fire claim: $35,000+. Prevent with Occupational Safety and Health Administration 1910.252 welding rules and National Fire Protection Association 51B hot work standards.


THE BASICS: HOW WELDING SHOPS WORK

Welding shops join metal using heat to melt and fuse parts. Heat comes from electricity or gas flames.

Simple Types of Welding (What You’ll See):

  • Arc Welding (Stick/MIG/TIG): Electric spark melts metal. Stick – uses a coated rod; common for repairs. MIG – feeds wire; fast for cars/frames. TIG – uses gas shield; clean for thin metal.
  • Gas Welding (Oxy-Acetylene): Oxygen + fuel gas flame cuts or welds. Why: Old-school, portable, cuts thick steel.
  • Plasma Cutting: Super-hot gas jet slices metal. Why: Fast cuts, less mess than torch.

Key Tools:

  • Welder Machine: Makes heat.
  • Gas Cylinders: Oxygen (green) and fuel (red).
  • Helmet/Gloves: Block sparks and UV light.

Why Inspect: Sparks fly 35 feet, fumes hurt lungs, gases explode if mixed. Most issues from clutter or poor setup.


 

INSPECTION CHECKLIST

WORK AREA SETUP

  • Clear space at least 35 feet around welding—no paper or trash Why: Sparks fly far and start fires.
  • Floors clean, no oil spills or clutter Why: Slips near hot tools cause burns.
  • Fire blankets or screens around work area Why: Stops sparks from spreading.

GAS CYLINDER STORAGE

  • Cylinders upright, chained, caps on when not used Why: Tipping causes leaks or explosions.
  • Oxygen and fuel gases stored 20 feet apart or with fire wall Why: Mix can explode if leaked.
  • No cylinders in tight spaces without air flow Why: Fumes build up fast.

VENTILATION AND FUMES

  • Fans or hoods pull fumes away from workers Why: Welding smoke harms lungs over time.
  • Air tested in small rooms—no high carbon monoxide Why: Invisible gas makes people pass out.
  • Respirators worn if fumes are strong Why: Extra lung protection.

FIRE PREVENTION

  • Fire extinguisher (ABC type) within 30 feet, current tag Why: Puts out small fires fast.
  • Hot work permit for each job, fire watch for 30 minutes after Why: Checks risks and watches for smoldering.
  • No flammable liquids near welding area Why: Vapors catch fire easily.

EQUIPMENT AND MAINTENANCE

  • Welder cables no frays, connections tight Why: Bad wires shock or spark.
  • Helmets and gloves no cracks, clean lenses Why: Protects eyes and skin from burns.
  • Monthly equipment checks logged Why: Spots wear before breaks.

QUESTIONS TO ASK OWNER

  1. “When was the last full safety check? Can I see the log?”
  2. “Gas cylinders—chained and separated? Leak tests?”
  3. “Ventilation system—pulls fumes out? Air tested?”
  4. “Any fires or close calls last year? What changed?”
  5. “Staff training—when last? Fire watch rules?”

RISK LEVELS

  • High = Gas leaks, no extinguisher → Suggest attention immediately, fix now
  • Medium = Clutter, old gear → Clean and check in 30 days
  • Low = Clear, tagged, trained → Best practice
