Question: 1 / 400

What precautions should be taken when using a CO2 type fire extinguisher?

Wear gloves

Do not use in an enclosed space

Carbon dioxide fire extinguishers work by removing the oxygen from the fire, which can make it difficult to breathe. Using a CO2 extinguisher in an enclosed space can lead to asphyxiation. It is important to use these extinguishers in a well-ventilated area and avoid using them in small, enclosed spaces. Options A, C and D are incorrect because while it is a good idea to wear gloves and shake the extinguisher well before use, these precautions are not specifically related to the use of a CO2 extinguisher. Additionally, while it is generally recommended to use fire extinguishers outdoors when possible, this is not the primary concern when using a CO2 extinguisher. The main concern is using it in a confined space where oxygen may become limited.
