METHANE Report: Major Incident Management for Paramedics

What Is the METHANE Report?

In the chaos of a major incident, clear and structured communication can be the difference between a coordinated response and a catastrophic failure. The METHANE report is the nationally recognised mnemonic used across UK emergency services to declare a major incident and transmit critical information rapidly and accurately to control rooms and incoming resources.

As a student paramedic or newly qualified clinician, understanding METHANE is not just an exam requirement — it is a core clinical and professional competency. Whether you are first on scene at a multi-vehicle road traffic collision, a building collapse, or a mass casualty event, you may be the person responsible for sending that initial report.

Breaking Down the METHANE Mnemonic

Each letter in METHANE represents a specific category of information that must be communicated. Here is what each stands for:

M — My Call Sign / Major Incident Declaration

The report begins with your call sign or identification, followed immediately by either declaring a major incident or standing by for further assessment. There are two possible declarations:

• Major Incident Declared: Used when you are certain the incident exceeds the capacity of normal resources and requires a full major incident response.
• Major Incident Standby: Used when the situation has the potential to become a major incident and you want resources to prepare without fully committing.

Being clear and decisive at this stage is critical. Hesitation or ambiguity can delay the mobilisation of additional resources.

E — Exact Location

Provide the most precise location possible. This should include the road name, junction, postcode, grid reference, or a recognisable landmark. In rural or motorway settings, use the carriageway direction and mile marker where available. Accurate location data allows the ambulance control room to direct resources without delay and prevents responders from attending the wrong area of a large scene.

T — Type of Incident

Describe the nature of the incident briefly and clearly. For example: a road traffic collision involving multiple vehicles, a chemical spill, a train derailment, or a structural collapse. This information helps control and incoming commanders anticipate the likely hazards, the types of casualties, and the specialist resources that may be required, such as HART (Hazardous Area Response Teams) or CBRN units.

H — Hazards

Report both current and potential hazards at the scene. These might include:

• Fire, smoke, or risk of explosion
• Chemical, biological, radiological, or nuclear (CBRN) contamination
• Unstable structures or vehicles
• Downed power lines or gas leaks
• Ongoing violence or security threats
• Environmental hazards such as water, ice, or difficult terrain

Accurate hazard information protects both casualties and the responders heading to scene. If you are uncertain, state what you can observe and flag that further assessment is ongoing.

A — Access and Egress

Provide information about the best routes into and out of the scene. Indicate where vehicles should approach from, where the ambulance parking point and loading point are located, and any routes that are blocked or unsafe. In a major incident, an uncoordinated approach can quickly lead to gridlock, preventing ambulances from evacuating casualties. Clear access and egress information is essential for the Bronze Ambulance Commander to establish effective scene geography.

N — Number of Casualties

Give an estimate of the number of casualties and, where possible, their priority using the triage sieve categories:

• Priority 1 (P1) — Immediate: Life-threatening injuries requiring immediate intervention
• Priority 2 (P2) — Urgent: Serious injuries that can wait a short time
• Priority 3 (P3) — Delayed: Minor injuries
• Priority 4 (P4) — Expectant / Dead: Unsurvivable injuries or confirmed death

Early casualty estimates are rarely precise, and that is expected. A rough figure gives control an essential starting point for resource planning. Update this information as the picture develops.

E — Emergency Services Present and Required

State which emergency services are already on scene and which additional services are needed. This includes police, fire and rescue, ambulance, coastguard, mountain rescue, or specialist teams. Also indicate whether you require NHS surge capacity, air ambulance, or medical incident commanders. This final element ties the whole picture together and enables a coordinated multi-agency response under the Joint Emergency Services Interoperability Principles (JESIP) framework.

METHANE in the Context of JESIP

The METHANE report does not exist in isolation. It sits within the broader JESIP doctrine, which governs how UK emergency services work together at complex or major incidents. JESIP principles — including co-location, communication, co-ordination, joint understanding of risk, and shared situational awareness — underpin every major incident response. METHANE is the primary communication tool that initiates and sustains that shared situational awareness across agencies.

As a paramedic, you will operate within the Bronze tier of the command structure (operational level), reporting to the Ambulance Bronze Commander. Understanding how your role fits within the Silver (tactical) and Gold (strategic) tiers will make you a more effective clinician and responder.

Practical Tips for Student Paramedics

When practising or revising METHANE, keep the following in mind:

• Rehearse the mnemonic until it is automatic — under stress, memory degrades quickly
• Use a structured aide-memoire or pad if available on your vehicle
• Remain calm and speak clearly over the radio — your composure sets the tone for the response
• Do not delay sending an initial report while waiting for a complete picture — send what you have and update regularly
• Always confirm your transmission has been received and understood

Summary

The METHANE report is a fundamental tool in pre-hospital major incident management. It provides a consistent, structured framework for communicating critical scene information at a time when clarity is most needed. For UK paramedics, mastering METHANE means being ready to lead from the front at the most challenging incidents you will ever face — ensuring that the right resources reach the right place at the right time, and that patients get the best possible chance of survival.
