What is the first step when responding to a suspected explosive device?

Establishing a safe perimeter is crucial when responding to a suspected explosive device. This action prioritizes safety by ensuring that personnel and civilians are at a safe distance from the potential blast radius of the device. By creating a secure area around the threat, responders can minimize the risk of injury or death in case the device detonates.

Once the perimeter is set, further assessment and response actions can be taken with a clearer understanding of the situation. This initial step also allows for better coordination of resources and personnel involved in the response. Prioritizing safety secures the environment for both responders and bystanders, ensuring that all further actions can be taken with reduced risk.
