CBRN incident management

Chemical Meteorology (CHEMET)

CHEMET can be used to track the dispersion of a chemical release. Telephone advice is available on demand which will give a simple short-range prediction of the anticipated behaviour of the plume. CHEMET is accessed through Hazard Manager, our online portal for Cat 1 & 2 emergency responders.

Read more about CHEMET including a case study about how we helped during the Buncefield oil depot fire in 2005.

FireMet

FireMet is a weather system designed to provide fire and rescue service (FRS) responders with the latest weather information to help them identify a safe approach when dealing with a major incident.

Developed in collaboration with the Department for Communities and Local Government (DCLG), FireMet is a password-protected, web-based system available to all FRS Incident Command Units and mobilising centres, as well as the National Coordination Centre. This system is available through Hazard Manager and is for fire service personnel only.

Fire Severity Index

We work with Natural England and the Countryside Council for Wales to help them prepare against fire threat with the Met Office Fire Severity Index. The index provides an assessment of the current day's fire severity and a forecast of the fire severity over the coming five days.

The national radiation monitoring network and emergency response system (RIMNET)

Following the world's worst nuclear disaster, the Chernobyl accident in 1986, the UK Government developed a National Response Plan to ensure that any similar emergency could be effectively managed. The National Response Plan was, and remains, a multi departmental and agency response plan with the now Department for Business, Energy and Industrial Strategy (BEIS) as nominated Lead Government Department for civil nuclear response.

The Met Office manage the national Radioactive Incident Monitoring Network (RIMNET) on behalf of the Government. The RIMNET system is a multi-purpose response tool and information sharing platform which supports the effective coordination of the UK's emergency response to domestic and overseas radiological events and can also be utilised in non-radiological events.

The RIMNET system brings together key elements of UK's emergency response to domestic and overseas nuclear accidents including the Met Office dispersion model. Through this modelling, the Met Office can provide a detailed picture of the potential dispersion of radioactive plumes over vulnerable areas sucah as cities and water sources. The maps are used by government and emergency planners via RIMNET.

The Met Office also maintains RIMNET's network of around 230 gamma dose rate monitoring sites across the UK, automatically measuring and analysing background radiation levels 24 hours a day, 365 days a year.

Joint Agency Modelling (JAM)

JAM is a Met Office-led, multi-agency modelling capability which estimates, forecasts and provides advice on radiation emergencies from incidents within the UK and overseas.

The JAM outputs are generated via an enhanced dispersion model and displayed as plume maps showing areas where thresholds for various impacts such as health, food restrictions and environmental contamination may be exceeded.

The plume maps and accompanying expert narrative from across the agencies provide the Government's Scientific Advisory Group for Emergencies (SAGE) with a single, coherent output to support decision making.

Procedures And Communications in the event of a release of Radioactive Material (PACRAM)

PACRAM is a rapid modelling service that predicts the trajectory of possible contamination plumes from UK nuclear power plants. The service is available to UK civil and military operators and the overseeing government bodies on request. The ultimate aim of PACRAM is to provide assessment quickly to enable the protection of the workforce and emergency services involved in initial response activities.
