Which action should be taken first by a security officer witnessing a severe vehicle accident on or near the property?

The priority in a situation where a severe vehicle accident occurs is to ensure that emergency assistance is summoned as quickly as possible. Calling 911 is the first critical action because it directly engages emergency services to provide medical attention and address any immediate dangers arising from the accident. Timely intervention by medical professionals can be vital to the injured parties’ recovery and safety.

While logging the incident, notifying a supervisor, or evacuating the area are important actions that may need to be taken subsequently, they should follow the immediate need for medical assistance. The safety of individuals involved in the accident and any potential hazards from the incident take precedence, making the prompt call to 911 essential.
