When should you call 911 in relation to using a fire extinguisher?

When using a fire extinguisher, it is essential to call 911 if the fire is spreading or has become out of control. This is because the safety of individuals and the need for professional assistance take precedence when a fire exceeds the capabilities of a portable extinguisher. An uncontrolled fire poses risks not only to the person trying to extinguish it but also to others in the vicinity and can quickly escalate, affecting a larger area and potentially causing injury or extensive property damage.

In such situations, notifying emergency services ensures that trained firefighters can respond quickly to manage the situation safely and effectively. It's crucial to recognize the limitations of fire extinguishers; they are meant to handle small, contained fires. If a fire shows signs of growing or threatens to spread, professional help is necessary for safety. Thus, understanding when to prioritize summoning emergency services is a vital part of fire safety practices.
