Double cylinder versions you can see on the Internet no longer exist as they did not work effectively whereas the single has just one control valve. It is easily refillable and can be maintained by any company. The single model is the same as the Chubb Fire 10kg CO2 fire extinguisher.
Despite being a lot heavier than portables (but, you won't be lifting it), wheeled fire extinguishers are simple to use. Just twist the wheel at the top of the valve, pull the large nozzle out of the holder, uncoil the hose, head towards the fire and twist the lever on the nozzle.
**British Standard 5306:3 requires the commissioning of extinguishers for businesses at your premises after delivery. We offer the option of commissioning only or with wall fixing from our specialist fire safety site SimplyExtinguishers.co.uk Our engineer will certify and label the extinguisher and issue a certificate for your insurance compliance.
