Industrial and urban accidents can take a wide variety of forms and their impacts vary considerably in both scale and nature.
In some cases these accidents will have very limited impacts beyond the immediate area and can be dealt with locally, although others can have cascading effects that will have a wider impact. Most industrial sites are regulated by the Health & Safety Executive and the Environment Agency to ensure they are safe. The Emergency Services have clear procedures for dealing with accidents on those sites.
The Control of Major Accident Hazards (COMAH) Regulations 2015 are in place to prevent major accidents involving dangerous substances and limit the consequences to people and the environment of any incidents which do occur.
