⚠️ Hazards of Hot Work

1. Fire & Explosion

Sparks can ignite flammable liquids, gases, or dust

Very high risk in confined or poorly ventilated areas

2. Burns & Injuries

Contact with hot surfaces, molten metal, or flame

Severe skin burns or eye injuries

3. Toxic Fumes & Gases

Welding fumes can cause respiratory issues

Exposure to harmful gases (CO, NOx)

4. Electric Shock

From welding machines or damaged cables

5. Eye Damage

Arc flash can cause arc eye (welder’s flash)

6. Explosion Risk

If work is done near pressurized vessels, tanks, or pipelines

🛡️ Precautions & Control Measures

1. Hot Work Permit System

Always issue a Hot Work Permit before starting

Ensure area inspection & approval

2. Remove Flammable Materials

Clear area of:

Fuel, oil, chemicals

Wooden/plastic materials

Minimum 10 meters safe distance (or cover with fire blanket)

3. Fire Protection

Keep fire extinguishers nearby (CO₂ / Dry Powder)

Assign a Fire Watcher during and after work (at least 30 mins)

4. Proper Ventilation

Ensure good airflow

Use exhaust systems in confined spaces

5. Use of PPE

Welding helmet / face shield

Fire-resistant gloves & clothing

Safety shoes

Respiratory protection if needed

6. Equipment Inspection

Check:

Hoses & regulators

Cables & connections

No leakage in gas cylinders

7. Isolation of Area

Barricade the work area

Put warning signs: “HOT WORK IN PROGRESS”

8. Gas Cylinder Safety

Keep cylinders upright & secured

Store oxygen & fuel gas separately

Close valves after use

9. Training & Competency

Only trained and authorized workers should perform hot work

10. Confined Space Control (if applicable)

Gas testing before work

Continuous monitoring
