Chemical and environmental incidents

Background

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.
