What is one of the first steps an EMS crew should take upon confirming hazardous material presence?

Identifying and communicating with incident command is crucial for ensuring the safety and effectiveness of the emergency response to a hazardous material incident. This step allows the EMS crew to establish a clear line of communication with the overall incident management team, which includes various agencies and specialists in hazardous materials.

By communicating with incident command, the EMS crew can receive vital information regarding the nature of the hazardous material involved, potential risks, and the strategies being implemented to manage the incident. This coordination is essential for not only ensuring the safety of emergency responders but also for planning the appropriate medical response for any affected individuals.

In contrast, while evacuating civilians may be necessary, it typically depends on the assessment of the situation and should be part of a coordinated response rather than the first action taken. Waiting for law enforcement does not actively contribute to the immediate handling of the hazardous material scenario and might delay necessary actions. Finally, immediate treatment of affected persons should only occur after ensuring a safe environment and adequate protection for EMS personnel, making incident command communication a priority.
