In which situation should you NOT use a fire extinguisher?

Using a fire extinguisher is appropriate only in certain circumstances where it is safe and effective to do so. When the fire is too large, this indicates that the situation has escalated beyond what a portable extinguisher can handle, which is typically suited for small, contained fires. Once a fire exceeds certain size parameters or begins to spread rapidly, attempting to extinguish it can put you in danger of injury or exacerbate the situation.

It is crucial to assess the size and intensity of the fire before deciding to engage with a fire extinguisher. Fire extinguishers have specific ratings for different types of fires, and as the size of the fire increases, the likelihood of successfully controlling it with a portable extinguisher drastically decreases. In such scenarios, it is often best to evacuate the area and call emergency services.

This highlights the importance of understanding fire behavior and the limitations of firefighting equipment. Being aware of when to use or not use an extinguisher can potentially save lives.
