Safe Apparel for Welding, Cutting, and Brazing Operations
The Problem
Welding, cutting, and brazing expose workers to sparks, slag, and intense heat. While gloves, hoods, and shields are essential, inappropriate clothing choices can leave the rest of the body at risk. Clothing made from flammable or synthetic fibres can catch fire or melt, causing severe burns or fatalities. Today, we’ll focus on these risks and how to select proper protective clothing to stay safe on the job.
Identify the Hazards
- Flammable Clothing: Synthetic materials like polyester, nylon, or blended fibres can ignite and melt onto the skin.
- Sparks and Slag: Can lodge in cuffs, pockets, or footwear and cause burns.
- Heat Transfer: Jewellery or inappropriate materials can trap or conduct heat, leading to injury.
- Contaminated Clothing: Grease- or oil-stained garments can act as fuel for a fire.
- Wear and Tear: Damaged or frayed PPE may no longer provide adequate protection.
Safety Practices and Preventative Measures
Avoid Synthetic Materials
- Do not wear clothing made from nylon, polyester, acrylic, or any cotton/synthetic blends — these are flammable and can melt onto the skin.
Choose Fire-Resistant Materials
- Wear clothing made from 100% cotton, wool, or specially designed fire-resistant fabrics.
- Ensure outerwear and undergarments — including shirts, pants, jackets, and socks — are all fire-resistant.
Shirt and Pants Guidelines
- Wear long-sleeved shirts with buttoned cuffs and covered pockets to prevent sparks from entering.
- Trousers should be cuffless and fully cover boot tops to stop slag from falling inside.
Footwear
- Wear fully laced boots or shoes to prevent hot slag or sparks from entering footwear.
Additional Head Protection
- Use a fire-resistant balaclava or skull cap under your welding hood to protect your head and neck from heat and UV radiation.
Clothing Care and Maintenance
- Keep protective clothing clean and free from oil, grease, or other flammable substances.
- Regularly inspect fire-resistant garments for fraying, holes, or other signs of wear — repair or replace as needed.
Remove Ignition Sources
- Empty all pockets of matches, lighters, or other potential ignition items before starting work.
Avoid Jewellery
- Remove rings, necklaces, and other jewellery, as these can trap heat, conduct electricity, or catch sparks.
Real-Life Case or Scenario
A worker wore a polyester-blend shirt while welding. Sparks ignited the shirt, which melted onto their skin, causing third-degree burns. The worker required months of treatment and rehabilitation. This incident could have been prevented by wearing fire-resistant clothing.
Employee Responsibilities
- Wear only fire-resistant protective clothing that covers your entire body.
- Check your clothing for damage or contamination before each shift.
- Remove jewellery and flammable items before starting work.
- Follow your company’s PPE and apparel safety policies.
Employer Responsibilities
Discussion & Questions
- What difficulties have you faced when choosing the right clothing for welding?
- Have you seen or experienced any clothing-related incidents during welding tasks?
Encourage team members to share experiences, concerns, or tips about their PPE and clothing.
Commitment/Action Plan
Let’s commit to inspecting our work clothing daily and ensuring we’re wearing flame-resistant materials. Starting today, take a moment before each job to check your clothing and remind your team to do the same. Safety is everyone’s responsibility.
Wrap-Up
Choosing the right protective clothing for welding can be the difference between staying safe and suffering a serious injury. By following these guidelines, we protect not only ourselves but also our co-workers. Thank you for your attention — let’s continue prioritizing safety every day.
Standards Overview
Under the Canada Labour Code and provincial/territorial occupational health and safety regulations, supported by guidance from the Canadian Centre for Occupational Health and Safety (CCOHS), employers (or employers and supervisors) must ensure:
- Workers are provided with or have access to appropriate personal protective equipment (PPE).
- Protective clothing minimizes the risk of injury from heat, flame, and molten metal.
- PPE is maintained in good condition and used correctly.
CCOHS also emphasizes:
- Workers must be trained in the safe use of PPE.
- Employers must monitor clothing and equipment for signs of wear or contamination.
- All PPE must be suitable for the task and compliant with applicable Canadian standards.
