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.

  • Bishopbriggs primary school evacuated after carbon monoxide leak

    A second primary school in an East Dunbartonshire town has been evacuated over a carbon monoxide leak. Pupils and staff temporarily left Wester Cleddens primary school in Bishopbriggs on Wednesday after a new alarm picked up traces of the gas. The fire service later confirmed a gas boiler had been at fault. The carbon monoxide alarm was fitted after nearby Balmuildy primary was evacuated and closed for several days following a leak two weeks ago. Some Balmuildy parents said children became ill before the leak was detected. It prompted the council to fit all of its schools with alarms which detect the odourless and colourless gas known as the "silent killer". East Dunbartonshire Council said children and staff had not been at risk during the Wester Cleddens incident. Anne Davie, the council's depute chief executive of education, said the school was evacuated after an alarm in the school's boiler room was activated. The faulty gas boiler was immediately switched off. "They [fire service] confirmed that there was no trace of carbon monoxide in the school and that the children and staff had not been at risk following this isolated reading in the boiler room," Ms Davie added. "Children and staff had located to the adjacent primary school and returned to Wester Cleddens when heating and hot water were restored." The gas boiler, which is a back-up to a biomass boiler, will now be repaired. The incident comes two weeks after Balmuildy primary was evacuated and closed for several days after a carbon monoxide leak. Parents said some children had been feeling ill before the evacuation, with some complaining of headaches and feeling sick. They have now set up a petition calling for all schools to be fitted with carbon monoxide alarms. The school's gas boiler has since been decommissioned.

"As the extent of the damage is not yet known further details about potential temporary school accommodation will be issued to parents in due course."

  • Carbon monoxide detected at a Bishopbriggs school

    Parents fear their children were exposed to deadly carbon monoxide after pupils fell ill days before a primary school was evacuated. They say children fainted and complained of headaches and feeling sick before a teacher at Balmuildy PS in Bishopbriggs, East Dunbartonshire, detected the toxic gas with an alarm brought in from home. One mum said she was met with a scene “like something out of a horror movie” when she arrived to collect her children at the local leisure centre following an evacuation of almost 400 pupils on Thursday lunchtime. East Dunbartonshire Council would not comment on the carbon monoxide claims and said their probe was continuing. It’s understood the call made to the fire brigade was over a suspected carbon monoxide leak. A dad, who has a daughter at the school, said: “I ran down as soon as I received the alert from the school and spoke to a fireman who said it was carbon monoxide. “I then ran round to the leisure centre and lots of the children were panicked and upset. A mum added: “My daughter has come home a few times feeling unwell and complaining of a sore head and crying. "In hindsight, it can only have been connected to the school. She said most of her class were feeling the same thing.” Another mother said: “A P3 pupil fainted and chairs were lined up outside the office for kids feeling sick yesterday.” One parent said she feared the worst when she was called to pick her child up. She added: “It was chaos at the leisure centre, like a scene from a horror movie. “There were loads of kids in tears, parents panicking. My first thought was, ‘Is it coronavirus?’” A source at the school claimed children had been feeling unwell for two weeks. They added: “Over the last few days, symptoms have been getting worse and all pointing to carbon monoxide poisoning – but still the council insisted school was safe.” Police, fire crews and paramedics were called to the school just after 12pm on Thursday before about 370 pupils were moved as a “precaution”.

  • Children and animals in danger at Dundee beauty spot due to toxic algae

    Parents and pet owners are being warned to keep their children and animals out of the water at a beauty spot because it is toxic. Dorothy McHugh of the Friends of Clatto, said there had been higher than ever levels of green algae at the reservoir. But she said that despite this she had been shocked to see not only dogs, but children in the water. She said: “We have had green algae at the reservoir before but this year it is very extensive, worse than I have seen before. “Usually it only covers sections of the water but this year it is much more widespread over a much larger area.” She added: “I always keep my dog on a lead when it is around because I don’t want to take the risk of him going in when it’s like this. “However, despite warning signs erected by the council I have seen many people allowing their dogs to go into the water. One day I was shocked to see a couple of young children, who were there with their parents, splashing around in the water at the edge.” Dorothy said: “I would warn people to stay out of the water while it is like this. “Hopefully if the cooler weather comes in the situation will get better but right now it has been pretty bad and people should definitely stay out of the water.” She added: “This is a long-term issue and something that the friends group is keeping in mind. “This is a significant blot on a beautiful area and will need to be tackled at some stage. “ Blue green algae (BGA) blooms may appear as green or greenish-brown scum on the surface of water and can contain toxins that can be harmful for animals if ingested.
