CO2 Fire Extinguishers Servicing London & Home Counties

Operating by displacing oxygen in a fire with carbon dioxide, CO2 fire extinguishers are marked with a black stripe and are used for all Class B fires (flammable liquids) and electrical fires.

AAI Security Systems stock CO2 extinguishers for use at all suitable premises across London and the Home Counties, all supplied, installed and maintained to NSI and BAFE-approved standards.

Fire extinguishers Is your business protected? Over 80% of businesses never recover from the effects of a fire. We can give you a full audit to ensure you are fully protected and covered for all your premises.

CO2 fire extinguishers are ideal for use in areas with sensitive electrical equipment, as they are not only effective on electric fires, they also leave no residue. AAI's fire safety experts are on hand to provide advice as to the correct extinguisher for your needs.

Maintaining your CO2 fire extinguishers is important to their ongoing operation. AAI offer regular inspections and testing, keeping your home or business safe from the threat of fire, as well as compliant with legislation governing the upkeep of fire fighting equipment.
