Hot Work Safety: 6 Essential Steps to Keep Everyone Safe
Hot work includes activities like welding, grinding, and cutting that generate heat, sparks, or flames. While essential in many industries, these tasks come with serious fire risks. That’s why hot work needs thorough planning, permits, and safety checks. Here’s a simplified guide to keeping hot work safe for everyone.
6 Essential Steps to execute hot work Safely
1. Get a Hot Work Permit and Complete a Safety Checklist
Before any hot work begins, you’ll need a Hot Work Permit. This document ensures everyone is aware of the job details and safety measures in place.
What’s in the Permit Checklist?
- Confirm the work area and list hot work tasks.
- Make sure all fire prevention tools, like fire extinguishers, are nearby.
- Remove or cover with fire blanket any flammable materials within 35 feet of the work area.
- Assign a fire watch to monitor safety throughout the job.
2. Prepare the Work Area and Use a Job Safety Analysis (JSA)
Preparation is everything in hot work. You’ll need to make sure the area is safe, flammable materials are cleared, and fire prevention equipment is ready.
Hot Work Prep Checklist:
- Work Area: Set up a designated space for hot work or use fire-resistant barriers like fire blankets.
- Clear Flammable Materials: Remove any items that could catch fire within a 35-foot radius. If they can’t be moved, cover them with fire blankets.
- Fire Extinguishers: Have the right type of fire extinguishers ready, like CO2 or dry chemical extinguishers.
- Fire Watch and Gas Test: Assign someone to watch for fires and ensure gas levels are safe with a detector.
- Water Hose: If possible, have a water hose nearby as an extra fire control measure.
3. Use Lockout/Tagout (LOTO) if Needed
If the hot work involves equipment that could accidentally power on, you’ll need to use Lockout/Tagout (LOTO) procedures. This locks the equipment in an “off” state to prevent accidental start-ups.
LOTO Steps:
- Identify all equipment power sources and isolate them.
- Place locks and tags on each energy source to secure it.
- Double-check isolation points regularly throughout the job.
4. Make Sure Only Qualified Workers Do Hot Work
Only certified workers should perform hot work because they understand the risks and how to stay safe. Make sure everyone is up-to-date on training and aware of potential hazards.
5. Use Certified and Inspected Equipment
All tools and equipment used in hot work—such as torches, grinders, and welding gear—should be certified and regularly inspected. This ensures that they’re safe and functional.
Equipment Checklist:
- Inspect tools for damage or wear before each use.
- Make sure hoses, gas cylinders, and connections are secure.
- Arrange for third-party inspections if needed to validate safety.
6. Wear the Right Personal Protective Equipment (PPE)
Wearing the right PPE is a must when doing hot work. The correct gear protects you from heat, sparks, and fumes. Here’s what you might need:
Examples of PPE for Hot Work:
- Flame-Resistant Clothing: Shirts, pants, or coveralls made from flame-resistant material.
- Welding Helmets or Face Shields: Shields that protect against sparks and harmful light.
- Safety Goggles: Essential to protect your eyes from sparks and debris.
- Heat-Resistant Gloves: Protects hands from heat and sparks.
- Hearing Protection: Use earplugs or earmuffs to reduce noise from grinding or cutting.
- Respirators: For areas with fumes or limited ventilation.
