Flammable chemicals pose a risk of fire and explosion. However, even when these substances have been removed from the containers which held them, there can be enough remaining to cause deadly explosions if workers do hot work such as welding or gas cutting on the empty or partially filled containers.
We have produced guidance for those who do hot work on containers which may have held dangerous chemicals.
Hot work on tanks and drums describes safety procedures for anyone who welds, brazes, solders or gas cuts any container or pipe that has contained a combustible substance.
While this guidance has not been updated to reflect current work health and safety legislation (the Health and Safety at Work Act 2015 and regulations), it may still contain relevant information and practices to keep workers and others healthy and safe.
Please read this guidance in conjunction with all relevant industry standards that apply to you as a PCBU. This guidance will be progressively reviewed and either updated, replaced with other guidance, or revoked.
