Cutting and Burning on Containers (Hot Drums)
Construction and general industry · Ver en español
Talking points
- Never cut, weld, or apply heat to any drum, barrel, tank, or container that has held flammable or combustible materials until it has been thoroughly cleaned, purged, and verified gas-free.
- Even a 'empty' container retains residual vapors. A single spark inside a drum with residual fuel vapor creates an explosion that launches the drum like a rocket.
- Cleaning methods include triple rinsing with water, steam cleaning, and filling with an inert gas (nitrogen or CO₂). The method depends on what the container held.
- After cleaning, test the atmosphere inside the container with a combustible gas detector. Readings must be below 10% LEL before any hot work begins.
- If the container's previous contents are unknown, do not attempt to clean or cut it. Treat it as hazardous and consult a specialist for proper identification and handling.
Ask the crew
Has anyone been asked to cut or weld on a container — and has it been verified empty, cleaned, and gas-free?
