Practical Notes

Always sweep floors clean of combustible materials within a 10m radius before starting hot work.

Combustibles that cannot be moved must be adequately protected by flame-proof covers or metallic shields.

Never perform hot work on drums or tanks that held flammable liquids without thoroughly purging, cleaning, and ventilating them first.

Maintain a trained fire watcher with ready-to-use fire extinguishers during and for at least 30 minutes after operations.
