What procedure must be followed during an EMS response to hazardous materials?

During an EMS response to hazardous materials, controlling area access and identifying hazards is a critical procedure. This step ensures that responders can assess the situation safely without putting themselves or others at risk. It involves securing the perimeter around the hazardous material scene to prevent unauthorized individuals from entering, which could lead to exposure or additional injuries.

Identifying hazards includes recognizing the specific type of hazardous material involved, understanding its properties, potential risks, and how it can impact human health and the environment. This information is essential for formulating an appropriate response strategy and ensuring the safety of both responders and the public.

While other actions such as using personal protective equipment, evaluating health assessments, and considering evacuations can be important in certain scenarios, they follow the initial critical step of controlling access and identifying what hazards are present. This foundational procedure helps guide subsequent actions taken by the EMS team.
