Safe Approach, Roadway Hazards and Changing Scene Conditions

Safety Priorities and Pre-Arrival Assessment

Scene size-up and safety assessment is an active, continuous process rather than a single checklist item. It begins the moment your unit is dispatched and does not end until the call is fully completed. Protect yourself and your partner first so you can provide care; assess and protect patients and bystanders according to the hazards present rather than applying a rigid ranking between them. If you become injured or incapacitated, you cannot help the patient and instead consume critical rescue resources.

A safe response requires understanding the limits of dispatch information. Information received en route is frequently incomplete, inaccurate, or based on the chaotic impressions of panicked callers. For this reason, EMTs must maintain a high index of suspicion for hidden hazards even on calls dispatched as routine medical complaints. A simple report of a person feeling sick can easily mask an environment containing hazardous fumes, violent disputes, or structural danger.

When dispatch explicitly reports violence, weapons, or an active domestic dispute, you must never drive directly into the hazard. Instead, stage at a safe location designated under local protocol until law enforcement confirms that EMTs can enter. During staging and approach for potentially violent calls, use emergency lights and sirens strictly according to dispatch instructions and local protocol, ensuring you never compromise roadway safety in the process. When there is a credible threat of violence or another specific hazard, stage in a safe location until the appropriate personnel have addressed the hazard and entry is permitted under local protocol.
