What are hazards associated with the use of CO2 fire extinguishers?

The hazards associated with the use of CO2 fire extinguishers primarily include impairment of vision, loud noise, and suffocation. When CO2 is discharged from the extinguisher, it can create a very loud noise, which might startle or disorient individuals nearby. Additionally, the rapid discharge of carbon dioxide can create a cloud that may obstruct visibility, making it difficult for personnel to navigate the area effectively during a fire response.

Moreover, CO2 extinguishers work by displacing oxygen in the environment, which can lead to suffocation hazards in confined spaces where there is insufficient oxygen for breathing. This can be exceptionally dangerous, as the user may not immediately recognize the lack of oxygen or may become incapacitated without warning.

In contrast, while consideration of increased fire risk, high explosion risk, and environmental pollution is important in the broader context of fire safety and extinguishing agents, these factors are not directly linked to the immediate operational hazards of using CO2 extinguishers. Consequently, those other options do not encompass the acute risks that are specifically associated with using CO2 for fire suppression.
