The blast at Rathburn Chemicals in Walkerburn on 10 January 2020 resulted in a laboratory, which was part of the factory, being demolished.
It was likely caused by excessive pentane vapour, generated by the company’s distillation process, overheating and being ignited by the site’s extraction system.
No one was injured by the explosion.
The Health and Safety Executive (HSE) found that Rathburn Chemicals had an inadequate system in place which failed to control the amount of steam and heat being generated during its distillation process. The company also failed to adequately detect any signs of overheating that could lead to flammable vapour being ignited.
Rathburn Chemicals (Manufacturing) Limited pleaded guilty to breaching Section 2(1) and Section 33(1)(a) of the Health and Safety at Work etc. Act 1974. The company was fined £40,000 and ordered to pay a victim surcharge of £3,000 at Lothian and Borders Sheriff Court on 20 September 2024.
HSE Inspector Isabelle Martin said: “This was a serious incident and it is fortunate that no one was injured by the blast. The explosion could have been avoided had Rathburn Chemicals simply carried out the correct control measures and safe working practices.
“This case also highlights the risks from distilling flammable substances, the need for reliable control measures and adequate training of employees. Companies looking for further advice on this issue can find readily available guidance on the HSE website.”
