What is the top priority in a hazardous materials incident?

In a hazardous materials incident, ensuring personal safety and securing the area is the top priority. This is critical because first responders must protect themselves from potential harm due to exposure to hazardous substances. If responders become casualties themselves, it not only compromises their safety but also hinders the overall response efforts, potentially putting victims and bystanders at greater risk.

Securing the area helps to establish a safe perimeter, preventing unauthorized access and protecting both the responders and the public from exposure. This step allows responders to assess the situation without the added danger of exposure to the hazardous material or the risk of further accidents.

While assessing victims, calling for additional support, and identifying the hazardous material are important actions that need to follow once safety is ensured, they cannot take place effectively without first establishing a secure environment for everyone involved. Prioritizing safety is essential in managing any hazardous materials incident properly.
