What is the consequences of using the wrong fire extinguisher?
The main danger with CO2 extinguishers is that they will cause upset in a confined space. They starve a fire of oxygen, but in a confined space they’ll also reduce the amount of oxygen available to breathe. Again, if children are going to be around the fire extinguisher, you have to be careful of accidental discharge.
What danger to personal exist when a carbon dioxide fire extinguisher is discharge in a small enclosed space?
When a CO2 extinguisher is used in a confined space there is danger that the user may become overwhelmed by the sudden increase in carbon dioxide emissions. This occurs as CO2 is an asphyxiant, and the confined space means oxygen will be replaced by the CO2 much faster.
When would it be dangerous to use a carbon dioxide extinguisher?
Carbon dioxide fire extinguishers, when used in the right circumstances can save lives. However, it would be dangerous to use a carbon dioxide fire extinguisher when dealing with flammable gases, cooking oils and fats, or in a confined space.
What should you not use a carbon dioxide fire extinguisher for?
Dangers: CO2 extinguishers should not be used on fires involving solid materials, such as paper, wood and fabric, and also are not suitable for use on flammable gases.
Can a carbon dioxide fire extinguisher be used on all fires?
They’re used for Class A fires only. CO2 fire extinguisher: Carbon dioxide extinguishers take away the oxygen element of the fire triangle. They also remove the heat with a cold discharge. They can be used on Class B and C fires.
What is the main cause of death in a fire?
smoke inhalation
The majority of fire-related deaths are caused by smoke inhalation of the toxic gases produced by fires. Actual flames and burns only account for about 30 percent of fire-related deaths and injuries.
What two fire extinguishers Cannot be used in confined space?
It is advised not use a CO2 fire extinguisher in a confined space, as it displaces oxygen and can asphyxiate the operator and other users.
How do you test a fire extinguisher for carbon dioxide?
Carbon Dioxide extinguishers are filled with non-flammable carbon dioxide gas under extreme pressure. You can recognize a CO2 extinguisher by its hard horn and lack of pressure gauge. The pressure in the cylinder is so great that when you use one of these extinguishers, bits of dry ice may shoot out the horn.
Why CO2 is not used for class A fire?
CO2s may be ineffective at extinguishing Class A fires because they may not be able to displace enough oxygen to successfully put the fire out. Class A materials may also smolder and re-ignite.
