A chemistry laboratory technician lost parts of three fingers and sustained a serious internal injury while preparing a highly sensitive explosive for use in a ‘fireworks’ demonstration to a class of children.
Bristol Magistrates’ Court heard the now retired staff member lost the top joints of his left hand index, middle and ring fingers and ruptured his bowel while preparing the explosive at Bristol Cathedral Choir School.
The Health and Safety Executive (HSE) prosecuting told the court the laboratory technician spent 12 days in total in hospital after the October 2014 incident. Although he returned to work in February 2015, he has since retired.
It was revealed that the preparation of explosive substances had been carried out in the school several times a year since 2009. The mixture in question and other substances had been used in ‘fireworks’ demonstrations.
The court also heard that other explosive substances, namely flash powder and gunpowder, were stored in the school’s chemistry storeroom.
HSE said the incident could have been avoided if the school had implemented clear management arrangements to control and review the risks posed by the chemicals used in its teaching activities.
Bristol Cathedral Choir School, of College Square, Bristol, admitted that it failed to ensure, so far as is reasonably practicable, the health and safety of its employees. It also admitted failing to conduct its undertaking in such a way as to ensure, so far as is reasonably practicable, that persons not in its employment, in this case its pupils, were not exposed to risks to their health and safety.
The school was fined a total of £26,000 [£8,000 for the section 2 offence and £18,000 for the section 3 offence] and ordered to pay £12,176 costs.
The HSE inspector commented that schools need to have clear health and safety arrangements in place for their staff and students.
