Fire extinguisher spares FAQs

Can I service my own fire extinguishers?

Basic monthly visual checks can be done in-house, but servicing should be carried out by a competent person in line with BS 5306-3.

Why are tamper seals and pins different colours?

Coloured seals and indicators help engineers tell service visits or extinguisher types apart at a glance.

What is Freezol?

Freezol is an antifreeze additive for water-based extinguishers in cold locations. Use it only where the extinguisher manufacturer allows it.
