Fire protection equipment

ODS in fire protection equipment

Ozone-depleting substances (ODS) were once used widely in firefighting equipment. Halons were used to fill equipment like hand-held fire extinguishers and built-in total flooding systems.

The use of halons in firefighting equipment is now banned, except for military and aviation uses.


What you must do

ODS obligations

If you discover any old firefighting equipment filled with halons or other ODS you must decommission it and dispose of the equipment safely as hazardous waste. Fire extinguishers should be labelled on the outside with what they are filled with.

To decommission fire protection systems and fire extinguishers, you must use a technician who holds the following qualification:
Fire Industry Competence Certificate Course, Class 1.

You must dispose of the equipment as hazardous/special waste at a licensed facility. See:
