In the event of a hazardous materials emergency, what is a key action to take?

Preventing smoking and keeping open flames away during a hazardous materials emergency is a critical action because many hazardous materials can be flammable or reactive. Open flames and smoking can ignite vapors or spills, leading to fires or explosions, which would significantly escalate the danger posed to people and the environment.

While securing the area from potential ignition sources is vital, it is equally important to follow procedural protocols, such as notifying emergency services and ensuring the safety of those nearby, which are implied in the broader context of managing such emergencies. Keeping open flames away helps minimize immediate risks, making it a key action in the initial response to a hazardous materials situation.
