Chemical and environmental incidents


A chemical incident is when a chemical is accidentally or deliberately released into the environment. The incident is managed and eventually resolved according to the chemical's:

  • physical state
  • quantity
  • danger level

Chemical incidents may involve:

  • a plume of gas
  • smoke
  • fire
  • contamination of water
  • contamination of land

Each of these has their own particular challenges for those trying to control the release and cleaning up any contamination to the environment, while ensuring the safety of the population surrounding the incident.

Environmental incidents are generally large scale incidents that affect a significant area. Examples of environmental incidents include:

  • wild fires
  • volcanic ash plumes
  • flooding due to storms
  • flooding due to high volume rainfall 

These incidents will require working with a number of different organisations over a number of different geographical areas.

Our key role in a chemical or environmental incident is to provide specialist operational support and advice to stakeholders. Our scientific and medical staff provide specialised advice on the public health implications of hazardous exposures. This support is given during acute incidents and for chronic exposures that result from incidents that extend over a longer period of time.

Data and surveillance

We operate the Scottish Environmental Incident Surveillance System (SEISS) (login required) which conducts surveillance of environmental incidents, involving risk to human health, at a national level in Scotland.

The system is based on a comprehensive incident database for Scotland, combining information on the occurrence of chemical, microbiological and radiological incidents with details of the:

  • response
  • sources of information
  • lessons learned

The system enhances the local, regional and national awareness of incidents and provides a nationwide forum for distributing information to participating agencies with responsibilities for responding to chemical and environmental incidents that have the potential to impact on public health.

  • East Dunbartonshire school evacuated over carbon monoxide leak

    A third primary school in East Dunbartonshire has been evacuated over a carbon monoxide leak. Pupils and staff temporarily left Craigdhu Primary School in Milngavie on Thursday after a new alarm picked up traces of the gas. It was later confirmed that a gas boiler was at fault. Carbon monoxide alarms have been fitted in all schools in East Dunbartsonshire after a gas leak shut Balmuildy primary in Bishopbriggs two weeks ago. The evacuation of Craigdhu primary came a day after a similar incident at Wester Cleddens primary in Bishopbriggs. Faulty boilers were also blamed for the leaks in Wester Cleddens and Balmuildy primaries. Council spokesman Thomas Glen said Craigdhu primary was evacuated after a carbon monoxide monitor in an external boiler house was activated. The fire service found that one of two gas boilers had developed a fault and it was immediately switched off. "They also confirmed that it was an isolated reading, there was no trace of the gas in the school and that the children and staff had not been at risk at any time," he added. "The boiler, which had previously been serviced in December 2019, was repaired and the heating and hot water at the school are functioning as normal." Following the gas leak at Balmuildy primary, some parents have set up a petition calling for all schools to be fitted with carbon monoxide alarms. They have said some children felt ill before the Balmuildy leak was detected, with some complaining of headaches and feeling sick.
