Initial Radio Report Guide for Firefighters

The First 15 Seconds Set the Tone

Your initial radio report — also called the on-scene report or arrival report — is the first piece of information the entire fireground gets about the incident. Every unit responding bases their mental preparation on what you say. Dispatch uses it to allocate resources. The chief driving in forms their initial plan from it. A sharp initial report tells everyone that a competent officer is on scene and in control. A garbled, disorganized one tells them the opposite.

Standard Format

While departments vary slightly, the nationally recognized components of an initial radio report are:

1. Unit identification and arrival: "Engine 7 on scene..."
2. Building description: Construction type and occupancy. "...two-story ordinary construction, single-family dwelling..."
3. Conditions found: What do you see? "...smoke showing from the second floor, Side Alpha..."
4. Actions being taken: What are you doing? "...Engine 7 is pulling an attack line to the second floor..."
5. Command established: "...Engine 7 is establishing Elm Street Command."
6. Additional needs: (if any) "...strike a second alarm" or "...send me an additional engine."

What to Include

• Construction type: Wood frame, ordinary, non-combustible, fire resistive, lightweight — this tells everyone how the building will behave under fire conditions.
• Number of stories: Affects ladder placement, search priority, ventilation tactics.
• Occupancy type: Single-family, multi-family, commercial, industrial. Drives life hazard assumptions.
• Visible conditions: Nothing showing, smoke showing, fire showing, fully involved. Be specific about location (which floor, which side).
• Immediate actions: What your company is doing right now. Attack, search, exposure protection, investigation.

What to Skip

Your initial report is not a novel. Leave out:

• Street address — dispatch already gave it, everyone has it on their MDT.
• Detailed tactical plans — those come after size-up, not during the first transmission.
• Color of the house, what the yard looks like, or anything that doesn't affect tactical decisions.
• Repeating information that dispatch already broadcast.

Aim for 10–15 seconds. If your initial report is longer than 20 seconds, you're saying too much.

Examples by Incident Type

Working Structure Fire

"Engine 7 on scene. Two-story wood frame, single-family dwelling. Heavy smoke showing from Side Alpha, second floor. Engine 7 is pulling a 1¾ to the front door, establishing Maple Street Command."

Nothing Showing

"Engine 7 on scene. Two-story ordinary construction, commercial occupancy. Nothing showing from Side Alpha. Engine 7 is investigating with a crew of three, holding the assignment. Establishing Oak Street Command."

Fully Involved

"Engine 7 on scene. Single-story lightweight construction, single-family dwelling, fully involved. Defensive operations. Engine 7 is establishing a blitz attack from Side Alpha. Strike a second alarm. Establishing Pine Street Command."

Vehicle Fire

"Engine 7 on scene. Single passenger vehicle fully involved in the parking lot, exposures at 30 feet on Side Delta. Engine 7 is attacking with a handline. No command established — this is a one-unit incident."

EMS — MCI

"Medic 7 on scene. Two-vehicle MVC, one car on its roof. Approximately four patients visible. Medic 7 is establishing triage. Requesting two additional ALS units. Establishing Highway 10 Command."

Hazmat

"Engine 7 on scene. Commercial warehouse, strong chemical odor in the area. No visible product release from Side Alpha. Engine 7 is holding at a safe distance and establishing Industrial Park Command. Request hazmat response."

The "Nothing Showing" Trap

"Nothing showing" does NOT mean nothing is happening. It means you don't see fire or smoke from your initial vantage point. You still need to investigate. Many working fires start with a "nothing showing" report from Side Alpha, only to have heavy fire on Side Charlie. Give the report, but get a 360 as fast as possible and update Command.

Practice Makes Permanent

Your initial radio report should be automatic — the same structure every time, filled in with the specifics of that incident. Practice it driving to calls. Practice it during tabletop exercises. Practice it until you can deliver it under stress without thinking about the format. The fireground is not the place to figure out what to say.
