What should be the temperature of the area when using a fire extinguisher?

The correct answer indicates that the area should be below 100 degrees Celsius when using a fire extinguisher. This is important because fire extinguishers are designed to operate effectively under certain temperature conditions. If the area is too hot, there is a risk that the extinguisher may not function properly, as high temperatures can affect the components of the extinguisher, including the gas pressures and chemical reactions contained within it.

Keeping the surrounding temperature below 100 degrees Celsius ensures the extinguishing agent can be released effectively and that the extinguisher is safe to handle. Moreover, working at lower temperatures reduces the risk of heat-related hazards for the person using the extinguisher.

The mention of the other temperature ranges like 50 degrees Celsius or allowing any temperature implies different safety risks and operational challenges, whereas maintaining the temperature below 100 degrees Celsius aligns with established fire safety practices.
