What should be done first when arriving at a HAZMAT scene?

When arriving at a HAZMAT scene, the first priority is to assess the scene for safety. This step is crucial because it allows responders to determine the immediate risks present, including potential threats to both personnel and the public. A safety assessment involves looking for hazards such as fire, unstable structures, weather conditions, and the presence of any hazardous materials.

By evaluating the scene, responders can make informed decisions on how to proceed, which is essential for ensuring their safety and that of others who may be in the vicinity. It helps to identify safe entry points, necessary personal protective equipment (PPE), and any immediate actions, such as containment or evacuation, that may be required to protect life and property.

Only after ensuring a baseline level of safety should responders move on to securing the scene, establishing command, identifying specific hazardous materials, or initiating evacuation procedures for nearby residents. This logical sequence is vital for maintaining safety and effectively managing the situation.
