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

  1. Wear gloves

  2. Do not use in an enclosed space

  3. Shake well before use

  4. Only use outdoors

The correct answer is: 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.
