What Is the METHANE Report?

When a major incident occurs — whether a multi-vehicle collision on the motorway, a train derailment, or a mass casualty event — the first paramedic or ambulance crew on scene carries an enormous responsibility. Before any treatment begins, before resources are mobilised, before command structures are established, one critical task must be completed: declaring the major incident and transmitting a structured METHANE report.

METHANE is the nationally recognised mnemonic used across UK emergency services to communicate essential information about a major incident quickly, clearly, and in a standardised format. It ensures that Ambulance Control, NHS Trusts, and partner agencies receive the same structured picture of the incident, enabling a coordinated and proportionate response.

Breaking Down the METHANE Mnemonic

Each letter of METHANE represents a specific category of information. Let's examine each element in detail.

M — Major Incident Declared (or Standby)

The first transmission must either declare a major incident or place receiving agencies on standby. A standby is used when the situation has the potential to become a major incident but is not yet confirmed. A full declaration is made when the incident is confirmed to exceed the capacity of the initial responding resources. This distinction matters — it triggers different levels of resource mobilisation at Ambulance Control.

E — Exact Location

Provide the most precise location possible. Use road names, junction numbers, landmarks, grid references, or what3words codes where available. Vague locations waste critical time. In rural or complex terrain, a grid reference or what3words address can be the difference between resources arriving quickly or getting lost.

T — Type of Incident

Describe the nature of the incident clearly. Is it a road traffic collision, a building collapse, a chemical spill, a fire, or a terrorist attack? The type of incident directly influences the specialist resources required — for example, a suspected chemical incident will trigger a HART (Hazardous Area Response Team) response, while a structural collapse may require Urban Search and Rescue (USAR) assets.

H — Hazards

Report any actual or potential hazards at the scene. These include:

This information is critical for the safety of incoming crews and for determining whether specialist teams are needed before standard paramedics can enter the scene.

A — Access and Egress

Advise incoming resources on the safest and most effective route into the scene, and how vehicles and patients will exit. Identify the Rendezvous Point (RVP) — a safe location away from the immediate hazard zone where incoming crews report before being directed forward. Poor access planning at a major incident can lead to gridlock, delayed treatment, and compromised evacuation.

N — Number of Casualties

Provide an estimate of the number of casualties and, where possible, a breakdown by priority using the triage sieve categories:

Initial estimates will be imprecise — that is expected and acceptable. What matters is giving Ambulance Control a working figure to begin resource calculations. These numbers will be updated as the situation develops.

E — Emergency Services Present and Required

State which emergency services are already on scene and which are still required. For example: "Police on scene, Fire Service requested, two ambulance crews present, requesting further ambulance resources, HART, and the Ambulance Incident Commander." This prevents duplication of responses and helps Ambulance Control prioritise dispatch.

Who Sends the METHANE Report?

In practice, the first clinician or crew on scene is responsible for sending the initial METHANE report, even if they are not yet in a command role. It is transmitted directly to Ambulance Control over the radio. As the incident develops and a formal command structure is established — including an Ambulance Incident Commander (AIC) and possibly a Medical Incident Commander (MIC) — subsequent METHANE updates will be sent through the command chain.

As a student paramedic, you may not be first on scene at a major incident during your clinical placements, but understanding METHANE is a core competency and is regularly examined in university assessments, OSCEs, and portfolio reflections.

The METHANE Report in the Context of JESIP

The METHANE mnemonic sits within the broader framework of the Joint Emergency Services Interoperability Principles (JESIP), which governs how police, fire, and ambulance services work together at complex or major incidents. JESIP principles include co-location of commanders, shared situational awareness, and a common language — of which METHANE is a central component.

Understanding how METHANE feeds into the wider JESIP doctrine will help you appreciate why standardised communication is so important when multiple agencies are operating at the same scene.

Common Mistakes to Avoid

When practising METHANE scenarios, student paramedics often make the following errors:

Practise METHANE reports aloud — in the car, in the library, with a study partner. The goal is to be able to deliver a clear, structured report under significant stress, with noise and distraction around you.

Applying METHANE in Your Studies and Clinical Practice

Most UK paramedic degree programmes include major incident management as a module or learning outcome, often assessed through simulation exercises or written examinations. Revisit your university's session notes alongside guidance from the Joint Royal Colleges Ambulance Liaison Committee (JRCALC) and JESIP documentation available via NHS England.

Practising METHANE as a structured verbal exercise — rather than just memorising the mnemonic — is what builds genuine clinical confidence. The mnemonic is a scaffold; your ability to populate it accurately under pressure is the skill.
