What is a critical task that must be performed by the first responders upon arrival at a technical rescue incident?

• A. Establish scene security
• B. Provide first aid
• C. Search for victims
• D. Set up lighting

Answer: (A)

Establishing scene security right after arrival is the first essential step because it creates a controlled, safe environment for both victims and responders. By securing the perimeter, you protect people from continuing hazards, prevent bystander interference, and set up a clear space for operations under command and control. This safety foundation makes it possible to perform other critical tasks—such as providing first aid, locating and rescuing victims, or setting up lighting—in a way that doesn’t expose anyone to additional risk. Without securing the scene, subsequent actions can be compromised by ongoing hazards and chaos, reducing overall effectiveness and safety.
