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.

  • Blaze on a hillside at Loch Doon

    Firefighters have spent a second night tackling a large forest fire in East Ayrshire. The emergency services were alerted to the blaze on a hillside at Loch Doon at about 18:50 on Saturday. At least five miles of hillside has been affected and the public have been asked to avoid the area. East Ayrshire Council said overnight that "progress" was being made and that a welfare centre had been opened in the nearby town of Dalmellington. Fire crews have been working in the area with support from Police Scotland and Forestry Commission Scotland. They are expected to remain at the scene monitoring the site and managing hot spot areas. The cause of the outbreak is still under investigation but the Scottish Fire and Rescue Service (SFRS) said recent dry weather has heightened the wildfire risk. A number of other fires broke out over the weekend, including one near Paul's Hill wind farm near Ballindalloch. SFRS Assistant Chief Officer Lewis Ramsay said: "Our crews across Scotland have had a challenging weekend attending numerous incidents. "Due to the outstanding collaborative working with land owners, The Forestry Commission and Police Scotland we have been able to ensure the safety of our communities. "I would like to thank the wider community for their ongoing support, the hard work of our partners, and the crews on the ground for their tireless efforts."

  • Fire crews tackle large grass blaze in Moray

    Firefighters have been tackling two large grass fires in Moray and East Ayrshire. The blazes near Ballindalloch and in Dalmellington came as the fire service warned of an increased risk of wildfires. Six appliances and a special wild fire unit were called out to a blaze near Paul's Hill Wind Farm at Ballindalloch which broke out at 22:55 on Saturday. A total of 35 firefighters eventually extinguished the blaze at about 15:20. A helicopter was also brought in to waterbomb the area. Mark Loynd, group manager with the Scottish Fire and Rescue Service, told BBC Scotland: "The fire was initially on two fronts and the crews had to gain access to a very rough terrain. "It was in a very inaccessible location with very limited water supplies so most of the fire has been put out by firefighters using beaters and knapsack sprays to attack the heather that was on fire." The cause of the fire, which covered an area of about 1km sq, is being investigated. Mr Loynd added: "I would like to thank the crews who have been working very hard over a protracted period. "And although it's still cool in the Highlands and Morayshire, the risk of wildfire is quite high because everything is very dry. So I would ask members of the public to please take care during the holiday period and going into the Easter weekend so we don't get any more wildfires unnecessarily."

  • Eight fire crews tackle heather and gorse hill blaze

    Eight fire crews were sent to battle a blaze in the Sidlaw Hills in Angus. The fire took hold in the Craigowl Hill area, several miles north of Dundee. Emergency services were called to the scene just after 6pm on Friday. They have now left the area, but will return in the morning to reassess the situation. A spokeswoman for the Scottish Fire & Rescue Service said controlled heather and gorse burning got out of control on rural land. She added: "We received a call at around 6pm and initially sent two appliances. One was from Kirriemuir and the other was from Forfar. "They requested additional back-up, so eight were sent in total. "The fire front was around two miles in area. "We have left the scene, but will be back out in the morning to reassess the situation."

  • Firefighters tackle large gorse blaze near Banff

  • Emergency crews stop chemical leak at Shotts bakery

    Emergency crews scrambled to stop a chemical leak from a Shotts bakery. A team from Scottish Fire and Rescue rushed to the scene at Torbothie Road around noon last Wednesday at the Bells bakery. It was later confirmed they were dealing with a suspected ammonia leak from a burst pipe. Crews remained on the scene for almost four hours. A Scottish Fire and Rescue spokesman said: “We were requested to assist emergency service partners at an incident involving suspected hazardous material at a business premises in Shotts. "Operations Control mobilised five fire engines and an environmental protection unit to the two-storey industrial premises, on Torbothie Road. “The building was fully evacuated, and firefighters thereafter carried out atmospheric testing and worked to make the area safe. There were no casualties.” Ammonia is a corrosive, colourless gas which can be dissolved in water to make an alkaline solution. The liquid solution can be used as a cleaning fluid. Exposure to high concentrations causes immediate burning of the nose, throat and respiratory tract. Exposure to low concentrations of ammonia in air or solution may produce rapid skin or eye irritation. A spokesperson for Bells said: “Bell Food Group Ltd (Hawthorn Bakery) and the residential Shotts area experienced two power cuts yesterday morning. “When electrical power resumed a power surge appeared to have resulted in an isolated equipment malfunction leading to a temporary leak in Bells’ ammonia refrigeration system. “Hawthorn Bakery was very quickly and successfully evacuated of all personnel immediately on detection of the leak. “The Fire Brigade and Police services were on site within minutes of being notified. Specialist refrigeration engineers were on site within 30 minutes to ascertain root cause. “Any gas leak has been stemmed and there is no danger to employees. No employees or local residents were injured, and the bakery was soon fully operational.”

  • Fife beaches closed by suspected oil spill

    Two beaches in Fife have been closed as a precaution while a suspected oil spill is investigated. Environmental health officials are trying to work out the source of the pollution on beaches in the villages of Limekilns and Charlestown. Residents reported a strong smell of oil on Monday, and pockets of pollution have been seen on the shoreline near the villages. Fife Council has warned people to avoid contact with the beach and the water. Environmental health officials from the local authority have posted signs at Limekilns and Charlestown beaches stating it has been "contaminated by an unknown pollutant". Forth Ports, which owns the nearby port of Rosyth, said the spill appears to be a light refined diesel. The firm also said its investigations on the scene suggest the spill came from a drain on the land. The suspected oil spill has been seen in the Firth of Forth and on the beaches. Joanna McFarlane, of the Charlestown, Limekilns and Pattiesmuir Nature Conservation Group, said there had been reports of "a really strong smell of oil" on Monday night. "Then this morning we woke up to this very sad sight of oil on our beach," she said. "This beach means a lot to the community here in Limekilns. Our local school has spent many hours helping to clean it and the community comes out regularly for beach cleans, not just for us but for the wildlife on this coastlines. "But this is out of our hands and I would like to find out who is responsible for it." Officials from Fife Council and the Scottish Environment Protection Agency (Sepa) have been at the beaches trying to trace the source of the spill. Sepa said early indications pointed to an isolated incident "which is not ongoing". Fife Council said warning signs had been erected and a clean-up operation had started. A spokesman for Forth Ports said: "We are currently investigating a reported small oil spill on the beach at Limekilns. It appears to be a light refined diesel. "On receiving the initial report, Forth Ports immediately sent a pollution response vessel to the area to investigate and nothing was found on the water. "Subsequent investigations from our on scene response suggest spill has come from a drain on the land. We are working with Sepa and Fife Council on this." Dunfermline and West Fife SNP MSP Shirley-Anne Somerville said: "This incident is very concerning. Urgent action is needed to ensure that lasting damage isn't caused to local wildlife and the surrounding environment. "I've contacted Sepa, in order to find out more about the source of this pollution, and the steps that are being taken to address the matter."

  • Harmful chemicals in a Glasgow burn to be flushed

    High levels of a toxic chemical which turned a Glasgow burn bright green are to be flushed into the River Clyde, the city council has said. The burn in Polmadie was fenced off after inspectors from environment watchdog Sepa discovered a concentration of hexavalent chromium. The element, which has been linked with cancer, is largely banned in manufacturing in the EU. Glasgow City Council said a proposal to flush out the burn had been agreed on. A spokeswoman said: "Following a site visit last week and confirmation about the temporary high concentration of hexavalent chromium in the Polmadie Burn, Heras fencing has been put in place to restrict public access and there is an agreed proposal to temporarily increase the flow of the burn, in a controlled way, to dilute the level of chromium." Environmental officers warned the contamination posed a risk to public health. The source of the chemical in the burn, according to Sepa (the Scottish Environment Protection Agency), was from historical chemical works which existed in the area from the 1800s until the late 1960s. Much of the waste by-products were used to backfill the former clay pits, near the West Burn in Shawfield. The council said chemicals contaminated the West Burn before seeping into the Polmadie Burn. To tackle the link, the West Burn was diverted into the River Clyde on 21 January and is in the process of being sealed up, according to council officials. Meanwhile temporary fencing was erected to restrict public access to the Polmadie Burn. It is thought the majority of chromium that was getting into the Polmadie Burn has now stopped. However small volumes could continue to seep in until the West Burn is fully sealed. Sepa expects the green colour will gradually disappear which will be helped by heavy rainfall. A proposal to allow more water to flow into the Polmadie Burn to dilute the chemicals was agreed on Tuesday following a meeting between Glasgow City Council, Sepa and Clyde Gateway. A spokeswoman from Sepa said pollution was the result of chromium ore processing residue from a former chemical works, previously located in the Shawfield area. She said work to stop contaminated ground water from entering the Polmadie Burn was due to be completed in the next couple of weeks. The flushing process requires a licence from Sepa and must be done in a controlled manner. The water will eventually flow into the River Clyde. It is expected to take place in the next two weeks.

  • Firefighters battle Innerleithen industrial unit blaze

    Firefighters have been battling a blaze at an industrial unit in the Scottish Borders. A number of crews were called to the scene at Traquair Road in Innerleithen at about 13:20. A warehouse building was well alight by the time they arrived at the scene of the incident. The Scottish Fire and Rescue service issued an appeal for the public to stay away from the Traquair Road area so firefighting efforts were not hampered. People in nearby homes were urged to keep their windows closed as a precaution.

  • Blaze at St Andrews University science building

    More than 30 firefighters tackled a blaze in a science building at the University of St Andrews in Fife. They were alerted to a fire involving suspected hazardous materials shortly before 17:00 on Sunday. Images posted on social media showed flames and smoke rising into the air from the four-storey building. The fire service said the building was evacuated and there were no casualties. Shortly before 23:00, they said the fire had been extinguished. At its height, eight fire engines including a height appliance were involved in the operation. In a statement issued late on Sunday, the fire service added: "Crews currently remain on the scene and are expected to remain so for some time as they work to make the area safe and extinguish any remaining hotspots." The university described the fire in its biomedical sciences building in North Haugh as "serious". It is shared by the university's schools of chemistry and biology. About 100 staff and postgraduate students work in its labs, where medically-focused research in organic and synthetic chemistry, virology and microbiology is carried out.
