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.

  • Blue green algae incident, Dumfries

    A PUBLIC health warning has been issued in Dumfries and Galloway after a blue green algae bloom was spotted locally. It has been reported on Loch Ettrick near Thornhill. Dumfries and Galloway Council released a statement today highlighting the toxicity of the algae to dogs and livestocks and advised against letting them, and humans, drink from contaminated sources. A spokesman said: “This advice remains in place throughout the season as Loch Ettrick blooms fairly regularly each year. “If you detect blue green algae, please report this to” Meanwhile, Dumfries and Galloway NHS have also put out an algae warning to bathers. Speaking about the risks to swimmers and pets, public health consultant Dr Andrew Rideout said: “There are dangers around swimming in natural waters at any time, but at this time of year a key concern is the presence of blue-green algae. “Although it’s referred to as algae, it’s actually a group of bacteria called cyanobacteria. It usually can’t get a foothold in moving water, but in areas of warmer, still water it can start to form – and it really does pose a significant risk. “Blue-green algae emits toxins. A human or pet swimming through it with their head just above the water can be at serious risk.” The bacteria cannot be seen by the human eye unless it clumps together. At this point, it can look like green flakes, greenish bundles or brown spots. Dead fish can sometimes be seen in areas of water with high concentration of the toxic bacteria. Dr Rideout listed symptoms of blue-green algae poisoning as vomiting, diarrhoea, seizures/fitting, weakness/collapse/unconsciousness, disorientation/confusion, drooling and breathing difficulties. He added: “Anyone who does venture into natural waters should be extremely vigilant for the presence of this algae, which may not always be immediately apparent. “Walking past waters with blue green algae should not pose a risk, but anyone who does enter these waters and starts to feel unwell should seek medical advice immediately.” Blue green algae has also previously been spotted at Carlingwark Loch and Milton Loch near Castle Douglas and at Castle Loch in Lochmaben.

  • People warned not to fish in water near powerplant after oil leak

    People are being told not to fish around a nuclear power station after an oil leak from an electricity substation on the site. East Lothian council yesterday advised visitors to Thorntonloch and Skateraw beaches, located next to Torness power station, to stay out of the water and keep their pets away. Now they have asked people not to fish in and around the beaches as well. The alert comes after an electrical fault at the substation caused an automatic fire protection system to activate leading to a mix of oil from the transformer and cooling water overflowing into the drainage system. Reports of discoloured water saw the local authority advise people using Thonrtonloch and Skateraw baeaches to stay out of the sea as water quality investigations were launched. The fishing ban is in place for “at least the next 24 hours” while waiting for the results of the water tests. It added that while it is believed the situations is improving clean up work has been taking place with teams using spill kits to block drains and contain and collect as much oil as possible. The council said it is believed the overflow has stopped but an absorbent boom had been installed as an additional safeguard. The substation is operated by SP Energy Networks and located within the grounds of EDF’s Torness Power Station. Tom Reid, the council’s head of infrastructure, said: “Teams responded swiftly to this incident and, working together with partner agencies, we are closely monitoring and managing the situation to protect the local environment. “We do believe it is an improving picture but, given the nature of the incident and the proximity of the beaches at Skateraw and Thorntonloch, we continue to ask members of the public to refrain from entering the water here at this time. “We also ask that owners do not allow pets to enter the water and that people refrain from fishing. “We will issue a further update to the public as our response to this incident continues.”
