The fire alarm sounds on level 9 of a busy office tower. Within seconds, the chief warden’s radio comes alive. Three floor wardens talk over each other. One says “all clear”, another says “still checking the east side”, and a third reports someone in a wheelchair near the lifts but forgets to say which floor. By the time the fire brigade arrives, the chief warden isn’t sure which floors are actually empty.
That kind of confusion is more common than most organisations would like to admit. Wardens are usually well-meaning staff volunteers, not trained emergency operators, and radios are often used only during the annual drill. Good radio protocols fix this. They turn a stream of noise into clear, useful information that helps everyone get out safely and gives first responders what they need when they arrive.
Why Radio Discipline Matters So Much
In an emergency, the chief warden relies almost entirely on reports from floor and area wardens to understand what’s happening across the building. Every unclear or incomplete message slows decisions down.
Australian Standard AS 3745 sets out how workplaces should plan for emergencies, including the roles in the emergency control organisation (ECO) and the need for communication systems that work. But the standard can’t make people speak clearly under pressure. That only comes from practice and agreed procedures, which is why radio skills should be a core part of any warden training program, not an afterthought.
Set Up Clear Call Signs
The first fix is simple. Give every role a call sign tied to its location, not the person’s name. “Level 9 warden” or “Floor 9” is far clearer than “Sarah”, especially when the regular warden is away and someone else has the radio.
The chief warden might use “Chief Warden” or “Control”. Deputies and communications officers get their own call signs too. Write these on a laminated card attached to each radio, so anyone picking it up knows exactly how to identify themselves. The same call signs should appear in your evacuation plan, alongside a list of who holds each radio, so the structure stays consistent when staff change.
Check the radios themselves, too. Batteries should be charged and tested regularly, and every warden should know which channel to use. A radio that’s flat or on the wrong channel is no better than having none.
Use a Simple Message Structure
Radio messages work best when they follow the same pattern every time. A common approach is to say who you’re calling, who you are, then the message. For example: “Control, this is Floor 9. Floor 9 is clear. All staff are at the assembly area.”
Keep messages short and factual. Avoid fillers like “um, so, I think maybe”. If there’s a problem, say exactly what and where: “Control, Floor 9. One person needing assistance at the eastern fire stairs, level 9. Two wardens stayed with them.”
The receiver should always confirm: “Floor 9, Control. Copy, one person needing assistance at eastern stairs, level 9.” That read-back confirms the message was heard correctly and lets others on the channel know the information has been received.
Agree on Key Words and Status Reports
Ambiguous phrases cause the most confusion. “All good” can mean the floor is clear, or simply that the warden is fine. Agree on standard terms during training and stick to them.
Many workplaces use simple status words, such as “searching”, “clear” and “not clear”, along with agreed terms for people needing assistance. Floor wardens should report in a set order: their floor’s status, any people needing help, any hazards seen, and confirmation once their area has been evacuated.
Your organisation’s emergency procedures should include these terms and the reporting sequence, so wardens learn them once and use them every time. Plans should also explain what to do if radios fail, such as using warden intercom phones or runners.
Channel discipline matters just as much. Radios only let one person speak at a time. If two people transmit together, both messages are usually lost.
Teach wardens to listen before pressing the button, keep transmissions brief and release the button promptly. The chief warden can control the channel by calling floors in order, for example from the fire floor outward, so reports arrive in a logical sequence. Urgent messages should start with an agreed priority word so others know to clear the channel.
Handing Over to First Responders
When emergency services arrive, the chief warden becomes the key link. Fire crews need clear, quick information: where the incident is, which floors are clear, which aren’t, and where any people needing assistance are located.
A simple written log helps. As reports come in, the chief warden or a communications officer notes each floor’s status on a whiteboard or form. When the incident controller arrives, the chief warden can hand over a clear picture in under a minute rather than relying on memory.
From that point, emergency services take control. Wardens follow their directions and continue to support the evacuation as needed.
Practise Until It Feels Normal
Protocols only work if people use them under stress. Run short radio drills outside of full evacuations, such as a ten-minute exercise where floor wardens report a simulated incident. Rotate who plays chief warden so more people understand the role. Include visitors and new starters in the scenario where possible, since real emergencies rarely happen when the most experienced wardens are on shift.
After each drill, debrief. What was unclear? Which messages were missed? Update procedures and call sign cards as people and floor layouts change.
First 5 Minutes is one Australian provider that delivers emergency warden training, including communication and coordination skills for floor wardens and chief wardens.
Clear Words Save Time
In an emergency, a clear radio message can save minutes, and minutes matter. Give every role a location-based call sign, follow a simple message structure, agree on standard status words and practise regularly. When the alarm sounds for real, your wardens will know exactly what to say, and first responders will know exactly where to go.
