Steel Cutting on Site Safety
Cutting structural steel on site using oxy-fuel torches, plasma cutters, disc cutters, and reciprocating saws generates sparks, fumes, noise, and sharp edges. Each cutting method has specific hazards that operatives must understand. Steel cutting often takes place at height or in areas with restricted access, adding further complexity. This talk covers the safety controls for cutting steel on UK construction sites.
Key Hazards
Fire from sparks igniting combustible materials in the cutting area
Metal fume inhalation from cutting galvanised, painted, or coated steel
Eye injuries from UV radiation, sparks, and molten metal splatter
Lacerations from handling sharp freshly cut steel edges and offcuts
Control Measures
- Obtain a hot works permit for all thermal cutting methods including oxy-fuel and plasma.
- Clear combustible materials from the spark zone and use fire blankets to protect adjacent surfaces.
- Wear welding-grade eye protection, flame-resistant clothing, and leather gauntlets during cutting.
- Provide fume extraction when cutting galvanised, painted, or coated steel to prevent metal fume fever.
- Ensure disc cutter guards are in place and the correct blade type is fitted for the material.
- Support the workpiece securely to prevent movement during cutting and handle offcuts with gloves.
- Maintain a fire watch for at least 60 minutes after the last thermal cut is completed.
- Brief all nearby workers on the cutting activity and ensure they are outside the spark and fume zone.
- Deburr and remove sharp edges from cut sections before they are handled or installed.
Remember
- Obtain a hot works permit for all thermal cutting and maintain a 60-minute fire watch
- Wear welding-grade eye protection, flame-resistant clothing, and leather gauntlets
- Use fume extraction when cutting galvanised, painted, or coated steel sections
- Ensure disc cutter guards are in place and the correct blade is fitted for the material
- Deburr all cut edges before handling or installing to prevent laceration injuries
