In respect of Co2 fire extinguishers
ADVANTAGES
ü It is a non-corrosive
gas, does not contain any solid material making it very clean extinguishing agent.
ü Will not conduct
electricity.
ü Does not leave any kind of residue. Co2 fire extinguishers are great for use in kitchens
as they have less risk of contaminating food preparation areas.
ü Has the longest service life
of most extinguishers, 10 years before an extended service will need to be carried out.
DISADVANTAGES
X Co2 is the most toxic gas when it comes to human health. It is a highly suffocating gas, whose concentration of even 9% in the breathing
air would make a person unconscious within minutes, special consideration should be taken before installing in confined spaces.
X Co2 fire extinguishers can extinguish flammable liquid fires but are not suitable for use on flammable solids, flammable gasses, or cooking fat fires.
X Very loud when used and an untrained person may think the extinguisher is not working correctly.
X If used incorrectly frost burns can result.
X Not field refillable, has to be returned to a refilling depot, so most companies use an exchange cylinder service that can be quite expensive.
