When assessing a person who has been exposed to chemicals, what should the EMT prioritize?

When assessing a person who has been exposed to chemicals, prioritizing scene safety is crucial for several reasons. First and foremost, ensuring the safety of the scene protects both the EMT and the patient from potential harm caused by ongoing exposure to hazardous chemicals. If the environment is unsafe, responders may become victims themselves, which could complicate the rescue effort and put more lives at risk.

In the context of toxicologic emergencies, factors such as the presence of toxic gases, unstable surfaces, or unwearable personal protective equipment need to be thoroughly evaluated before any patient care can be administered. Only after confirming that the scene is secure can the EMT safely proceed with assessing the patient, identifying the chemical involved, decontaminating the patient, or gathering history from witnesses.

Each of the other options is important in a comprehensive assessment process, but they hinge upon first establishing a safe environment. If the scene is not safe, any interventions made can lead to further complications or harm. Recognizing the priority of scene safety ensures that patient care can be effectively and efficiently executed in a manner that minimizes risks to everyone involved.
