When fire trucks or police vehicles arrive at an Australian workplace during an emergency, one of the most important moments in the entire response takes place in the first 60 to 90 seconds. The Chief Warden or the delegated Communications Officer walks up to the senior officer on arrival, briefs them on the situation, and hands over operational control. What is said, what is not said, and how it is delivered can shape the emergency service response for the rest of the incident.

Yet this handover receives remarkably little formal attention in most workplace training. Emergency plans mention it in a single line. Wardens are told “brief the fire brigade on arrival” without a structured framework for what that briefing should contain. In real incidents, the Chief Warden often improvises the briefing under stress, misses critical information, or provides so much detail that the important elements are lost.

This guide covers the handover in operational depth: what the senior emergency service officer needs to know, what order to say it in, what to withhold until asked, and how to physically manage the handover so it works. It builds on our companion guides on the role of fire wardens in evacuation planning and the AS 3745 Emergency Control Organisation.

Why the handover matters more than the response before it

Everything the Emergency Control Organisation (ECO) does before emergency services arrive is preparation for the arrival. The evacuation, the sweep, the roll-call, the isolation of the incident area: all of it produces information the emergency services need. The handover is the point at which that information transfers from the ECO to the responding agency.

A handover that goes well saves emergency service time, focuses the response on the actual problem, protects the ECO members from misdirected instructions, and demonstrates the organisation’s competence and duty of care. A handover that goes badly wastes minutes at the moment when minutes matter most, sends the response to the wrong location, misses vulnerable occupants, and creates the impression that the workplace was not prepared.

Who takes control on arrival

Under AS 3745:2010, the Chief Warden manages the response until emergency services arrive. On arrival, the senior emergency service officer takes operational control. This is not a shared arrangement, and it is not the Chief Warden’s choice. The transfer is:

• Fire and Rescue: fire and hazmat incidents. The senior on-arrival officer is typically a Station Officer or Commander.
• Police: bomb threats, active threats, civil disorder, and any incident involving violence or the possibility of criminal action. The senior on-arrival officer is typically an Inspector or Senior Sergeant.
• Ambulance: medical incidents. Coordination with paramedics is typically direct rather than a formal handover, unless the medical incident is part of a broader emergency.

For compound incidents (fire with hazmat, medical incident during a bomb threat), the on-arrival senior officer from the lead agency takes control. Multi-agency incidents typically have a joint incident command established once all agencies are on scene.

The structured briefing: METHANE

The most widely used briefing framework in Australia and internationally is METHANE (Major incident, Exact location, Type, Hazards, Access, Number of casualties, Emergency services), adapted from the UK ambulance sector but now used across Fire and Rescue, police, and multi-agency responses. The framework covers seven elements the senior officer needs to know, in order:

M – Major incident declared or standby

State whether this is a major incident (multiple casualties, significant infrastructure impact, multiple agencies required) or a standby situation. For most workplace incidents, this is stated implicitly through the nature of the incident.

E – Exact location

The specific location of the incident within the facility. Not “the office”. Not “level 5”. “Level 5, west wing, server room, adjacent to the emergency stair on grid line C.” Provide grid references, room numbers, and cross-references to the evacuation diagrams the emergency service will already have.

T – Type of incident

Fire, bomb threat, hazmat release, medical, active threat, structural failure. Be specific. “Fire in the server room, appears electrical in origin, actively burning at time of ECO retreat five minutes ago” is more useful than “there’s a fire”.

H – Hazards, present and potential

What hazards are known to be present in or around the incident? Hazardous materials stored on the affected floor, gas supply, electrical vulnerabilities, structural concerns, adjacent high-risk activities, Personal Emergency Evacuation Plan (PEEP) occupants who could not be evacuated. This is often the most valuable content of the entire briefing.

A – Access routes and rendezvous

How the responding units should approach the building and where the ECO command point is located. If a preferred approach route exists (e.g. to avoid an unsafe area), state it. Confirm where the Chief Warden and Communications Officer are located.

N – Number of casualties or occupants

Confirmed casualties, suspected casualties, occupants not yet evacuated, PEEP occupants and their locations, occupants requiring specific support (mobility, medical, language). Provide numbers and locations, not just categories.

E – Emergency services required and any already on scene

Which services have been called (Fire and Rescue, police, ambulance). Which services are already on scene. Which services you assess are still needed. This helps the incoming service coordinate with the broader multi-agency response.

A worked briefing example

The METHANE structure in practice, for a small fire in an office building:

“Sir, Chief Warden here. Minor incident, no major declaration. Fire located on level 5, west wing, server room adjacent to the emergency stair on grid C. Electrical fire, appears to have started at 09:12, currently containable but growing. Hazards: server room contains a lithium-ion battery uninterruptible power supply (UPS), potential toxic gas venting. No hazardous chemicals in the immediate vicinity. Access via the eastern entrance is clear. My command point is at the eastern entrance forecourt. Occupants: level 5 fully evacuated except for one occupant in room 507 with mobility impairment, currently sheltering with a warden as her PEEP directs. Confirmed no casualties at time of last report. Services on scene: Fire and Rescue currently, no other services requested. Ambulance advised on standby.”

The briefing above takes approximately 45 seconds to deliver. It gives the senior officer everything needed to direct the initial response, positions the ECO as competent and organised, and creates the basis for the next 20 minutes of coordination.

What to withhold until asked

The METHANE briefing is the essential content. Additional information should be provided when asked, not proactively. This includes:

• Detailed building history, past incidents, or planning permissions
• Detailed occupant demographics beyond what is operationally relevant
• Detailed opinions about what caused the incident (unless there is direct observational evidence)
• Detailed information about internal politics, tenant relationships, or organisational context
• Detailed operational history of the building systems

The senior officer will ask for what they need. Provide it. Do not overload the briefing with context that will not affect the immediate response.

Physical management of the handover

The handover is a physical event as well as an informational one. Where the Chief Warden stands, how they present themselves, and what they carry all shape how the briefing is received.

• The Chief Warden meets the senior officer at a pre-designated command point, ideally the primary access point for the responding vehicles
• The Chief Warden wears their identifying gear (white helmet or vest under AS 3745), so they are immediately identifiable as the on-site incident commander
• The Chief Warden carries the essentials: the current evacuation diagram, the occupant list, the ECO contact list, any relevant PEEPs, a pen and paper for capturing service instructions
• The Chief Warden does not carry mobile phones into a suspect-item cordon (see our guide on bomb threat procedures)
• The Chief Warden delegates to the Deputy Chief Warden or Communications Officer during the briefing to ensure the ECO continues functioning
• The Chief Warden asks the senior officer where they would like the ECO to position for the remainder of the incident

Incident type variations

The METHANE framework applies across all incident types, but the specific content varies. Some incident-specific notes:

Fire and Rescue incidents (fire, hazmat, structural failure)

Emphasise hazards, especially chemical or biological hazards, gas supply, electrical, structural concerns. Confirm which occupants (if any) have not been evacuated and their locations. Confirm PEEPs and their assistants’ status. Provide the evacuation diagram and any hazardous material register.

Police incidents (bomb threat, active threat, civil disorder)

Emphasise the threat: number of individuals involved, last known location, weapons observed, direction of movement. For bomb threats, provide the exact wording of the threat, the channel of receipt, and the credibility assessment made by the ECO. For active threats, provide the location of any suspect-item cordon and the maintained 25-metre electronic exclusion zone. See our bomb threat procedures comprehensive guide.

Ambulance incidents (medical)

Emphasise patient location, patient condition (as observed, not as speculated), first aid delivered so far, patient allergies or medical history where known, direction of ambulance approach for the fastest patient access. Send a warden to meet the ambulance at the entrance to escort them directly to the patient.

Multi-agency incidents (compound)

Emphasise which agencies are already on scene, what each agency is doing, and where the joint incident command is being established. Multi-agency incidents typically resolve into a unified command structure within 15 minutes; the Chief Warden should support this rather than manage separate handovers to each agency.

After the handover

Once the senior officer takes operational control, the Chief Warden’s role shifts. Key responsibilities:

• Provide continuing information as it becomes available (updated occupant counts, discovered hazards, staff observations)
• Coordinate the ECO under the senior officer’s direction
• Manage occupant welfare at the assembly area
• Maintain the incident log with timestamps of every decision and communication
• Support the emergency service liaison with site knowledge (utility shutoffs, system controls, key personnel)
• Prepare for the media if the incident attracts attention (with organisational communications support)
• Do not interfere with the emergency service response
• Do not authorise re-entry to the building without explicit service approval

The debrief after the incident

The handover itself is a debriefable component of every incident. Was the briefing complete? Was the location accurately given? Were hazards identified before the service arrived? Did the ECO position correctly? See our companion guide on the post-incident debrief for the debrief structure. The handover is often the highest-value learning point in the debrief because it is the moment the ECO’s preparation is exposed to external assessment.

Training the Chief Warden for the handover

Handover competence is a trained skill, not a natural one. Chief Wardens who have never delivered a METHANE briefing in a training environment will struggle to deliver one under stress. Effective handover training includes:

• METHANE structure drilled to memory
• Scenario-based briefings with feedback from an experienced facilitator
• Handover exercises that involve a real (external) senior officer role-player
• Coverage of the incident-type variations (fire, police, ambulance, multi-agency)
• Physical management of the handover (positioning, identification, documents to carry)
• Post-briefing behaviour and continuing coordination

For Chief Warden-specific training that covers the handover in depth, see our Chief Warden training program.

Common handover failures

From more than 40 years of Chief Warden training delivery and post-incident debriefing across Australian facilities, these are the recurring failures we see in real workplace handovers:

• The Chief Warden is not identifiable. No helmet, no vest, no clear indication of who the incident commander is. The senior officer has to search for the point of contact.
• The Chief Warden briefs on the specific incident but omits the hazards. The senior officer discovers the lithium-ion UPS on entry.
• The Chief Warden overshares. The senior officer receives 10 minutes of building history and no operational content.
• The Chief Warden shares speculation as fact. Origin theories, cause theories, motivation theories, offered without evidence. The senior officer must sort the evidence from the speculation.
• The Chief Warden does not have the evacuation diagram or occupant list to hand. Everything is verbal from memory. Details are lost.
• The Chief Warden continues to run the response after handover. The senior officer has to redirect the ECO members who are looking to the Chief Warden rather than to the incident command.
• The Chief Warden does not brief on the PEEP occupants. The senior officer does not know that a mobility-impaired occupant is still in the building.
• The Chief Warden does not maintain the incident log. The debrief is later constructed from partial recollection.

Build handover competence into your ECO

The handover is one of the most consequential moments in any workplace emergency response. Training your Chief Warden and Deputy Chief Warden in the METHANE briefing structure, physical handover management, and post-handover coordination is one of the highest-value investments in your emergency capability. Across more than 40 years of AS 3745-compliant Chief Warden training, First 5 Minutes has helped Australian organisations make the handover a strength rather than a weak point.

Frequently asked questions

What is the METHANE framework?

METHANE is a structured briefing framework used by emergency services in Australia and internationally. It covers Major incident status, Exact location, Type of incident, Hazards, Access routes, Number of casualties or occupants, and Emergency services required. It is the recommended structure for a Chief Warden briefing to the senior on-arrival emergency service officer.

Who does the Chief Warden hand over to?

The senior on-arrival officer from the lead responding agency. For fire and hazmat, this is typically a Fire and Rescue Station Officer or Commander. For police incidents, an Inspector or Senior Sergeant. For medical incidents, coordination is typically direct with paramedics rather than a formal handover.

What if two agencies arrive simultaneously?

Brief both. Provide the METHANE briefing to the officer from the lead agency for the incident type (Fire and Rescue for fire, police for bomb threat) and confirm to the other agency that they will receive coordinated tasking through the multi-agency incident command.

How long should the handover briefing take?

45 to 90 seconds for a routine incident. Up to two to three minutes for a complex or compound incident. Longer than that and the briefing is likely overloaded with context that should be provided when asked.

Does the Chief Warden still have any authority after the handover?

Not for the incident response itself. The senior officer has operational control. The Chief Warden retains responsibility for the ECO under the senior officer’s direction, for occupant welfare at the assembly area, for the incident log, and for site knowledge that supports the response.

What if the emergency service asks the Chief Warden to do something unsafe?

Rare, but not impossible. If any specific instruction crosses a WHS line, the Chief Warden should raise the concern directly with the senior officer and document the exchange in the incident log. The Chief Warden retains their WHS duty of care for the ECO and building occupants.

Should the Chief Warden accompany the emergency service into the building?

Only if invited by the senior officer, and only in circumstances where their site knowledge would clearly help and the risk profile permits. In most incidents, the Chief Warden remains at the command point.

What if the Chief Warden is out of the building when the incident happens?

The Deputy Chief Warden takes the role. This is why AS 3745 expects Deputy Chief Wardens to be trained to an equivalent standard, and why the substitution rules should be documented in the emergency plan. In multi-site organisations, the Chief Warden for the specific facility manages the handover; a corporate-level Chief Safety Officer or similar does not.

How is a compound incident (fire and hazmat, or medical during a bomb threat) handled?

The senior on-arrival officer from the lead agency takes control. Additional agencies coordinate through incident command. The Chief Warden briefs the lead agency and continues to feed information as it develops. Multi-agency responses typically resolve into a unified incident command within 15 minutes.

What about media on scene?

Media may arrive with or shortly after emergency services. The Chief Warden does not brief media. Media requests are directed to the organisation’s communications function, or, if none exists, deferred with a “we will provide information when we can” holding response. Do not speculate about cause or outcome to media.

What happens after the incident is resolved?

The senior officer will typically debrief with the Chief Warden briefly on scene, confirm any residual actions (utility isolations, re-entry protocol, ongoing hazards), and hand back control of the building. The Chief Warden captures this in the incident log. A formal debrief follows within 24 to 72 hours.
