What should be the first action taken when approaching a hazardous materials incident?

The first action to take when approaching a hazardous materials incident is to ensure personal safety and establish a safe distance. This action is crucial because approaching a scene without assessing for potential hazards can put the responder and others at risk. Establishing a safe distance allows the responder to evaluate the situation without being exposed to harmful substances, explosions, or other dangers that may be present.

Safety protocols are designed to prioritize personnel before any other action is taken. This approach helps responders make informed decisions about how to proceed, whether that involves calling for additional assistance, identifying hazardous materials, or more complex actions like evacuation. The personal safety of responders is paramount as it ensures that they can effectively manage the incident without becoming victims themselves.

In contrast, while calling for backup may be necessary afterward, it should not precede ensuring personal safety. Identifying hazardous materials is a critical step but can only be safely performed once the responder has established a safe distance. Starting an evacuation is important during an incident but should not take precedence over assessing personal safety to avoid further complications during the emergency response.
