What is typically the first step to take in an emergency involving hazardous materials?

In an emergency involving hazardous materials, the first step is to assess the situation and ensure personal safety. This is critical because the primary concern in any emergency, especially one involving hazardous substances, is to protect yourself and others from potential harm. A thorough assessment allows you to understand the nature of the hazardous materials involved, the extent of the incident, and whether there are immediate dangers, such as exposure to toxic substances or risk of fire or explosion.

Taking this precaution before any other actions, such as cleanup or contacting relevant parties, ensures that you are in a safe position to act effectively without putting yourself or others at further risk. It also allows for better-informed decisions as you begin to address the situation.

Following personal safety, other steps can be taken, but prioritizing safety helps establish a secure environment to manage the incident effectively.
