Overview
The Welding & Hot Work Module provides hazards and controls for welding, cutting, grinding, and other spark-producing operations.
Hot Work Hazards
Fire/Explosion
- Sparks and slag
- Hot metal projection
- Flammable atmospheres
- Combustible materials nearby
Fumes and Gases
- Welding fumes
- Hexavalent chromium
- Manganese
- Ozone
- Metal fume fever
Radiation
- UV radiation
- Infrared radiation
- Intense visible light
Physical
- Burns (contact and radiant)
- Eye injuries
- Noise exposure
- Posture/ergonomic
Hot Work Controls
Fire Prevention
- Fire watch (during and after)
- Combustible clearing (35 ft minimum)
- Fire extinguisher present
- Spark containment
- Hot work permit
Respiratory
- Mechanical ventilation
- Local exhaust
- Respirator (when ventilation inadequate)
- Fume extraction torch
PPE
- Welding helmet (proper shade)
- Safety glasses under helmet
- FR clothing
- Welding gloves
- Leather apron
- Steel-toe boots
Fire Watch Module Integration
This module works with the Fire Watch Module:
- Identity registration
- 15-minute check-ins
- Post-work monitoring (60-180 min)
- Relief tracking
- Immutable documentation
