đźš’ BEHIND THE HELMET | ENTRY CONTROL OFFICER (ECO)
When firefighters enter a burning building wearing Breathing Apparatus (BA), there’s someone outside keeping track of every move they make. That person is the Entry Control Officer (ECO).
The ECO plays a critical role in keeping our firefighters safe while they work in what can be extremely dangerous and unpredictable conditions.
👨‍🚒 So, what does an ECO actually do?
Before entering a structure, each firefighter reports to the ECO and hands over their personal tally, which displays their surname and cylinder air pressure. The ECO records their details on the entry control board, grouping them into crews of two or three, with two-person crews being the most common.
The crew’s task is confirmed before entry. This could be a fire attack, search and rescue, or another operational objective, along with where they need to go.
⏱️ Time is critical.
Once the crew enters, the ECO records their entry time and monitors how long they’ve been inside. They must manage crews’ working times, coordinate relief crews and ensure an emergency crew is arranged and ready should something go wrong and a MAYDAY be declared.
When firefighters safely exit the structure, they report back to the ECO and collect their tallies, closing the loop and ensuring everyone is accounted for.
đź“» Communication is everything.
The ECO must maintain clear, calm and effective radio communications with firefighters inside the structure and officers managing the incident on the fireground. They need to know who is inside, where crews are operating and what’s happening, so the right decisions can be made at the right time.
It’s a role that requires concentration, organisation and the ability to stay composed under pressure. While the ECO may be standing outside the fire, the responsibility they carry is just as real.
Because behind every firefighter working in a hazardous environment is a team working to make sure they come home safely.
Behind every helmet is a volunteer. And behind every crew entering a structure is a system of safety, teamwork and trust.
