A Scottish company has been fined £40,000 after an explosion at its factory in the Borders.

On January 10, 2020 a laboratory at Ruthburn Chemicals in Walkerburn exploded and later had to be demolished.

A Health and Safety Executive (HSE) investigation found 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 which could lead to flammable vapour being ignited.

The company pleaded guilty to breaching Section 2(1) and Section 33(1)(a) of the Health and Safety at Work etc. Act 1974 and was fined £40,000 and ordered to pay a victim surcharge of £3,000.

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.”

Rathburn Chemicals has been contacted for comment.
