Vapourisers are devices that convert liquids to gases. They act like boilers, but instead of boiling water they boil hazardous substances.
Vapourisers are directly or indirectly fired. When directly fired, an open flame is directly applied to the heat exchange surface, which then vaporises the substances. Indirectly fired means the heat is provided by an outside source such as steam or electricity.
Manufacturing or importing vapourisers
Vapourisers must be designed, constructed and installed to comply with Part 17, subpart 10 of the Health and Safety at Work (Hazardous Substances) Regulations 2017(external link).
Check the vapouriser record to find out if your vapouriser has already been approved.
Getting a vapouriser approved
To get a new type of vapouriser approved, send the completed application form with all the necessary documentation to WorkSafe.
Installing and using vapourisers
Part 17, subpart 10 of the Health and Safety at Work (Hazardous Substances) Regulations 2017 contains specific requirements for the installation of vapourisers including separation requirements.
When installed, vapourisers are part of a stationary container system, that is, a fixed tank and associated pipe work and fittings. You may need to get a stationary container system compliance certificate.
