According to the BBC, Dorset Fire and Rescue Service were at a loss to explain how 25 litres of a hypochloride solution, used to clean pools, had become mixed with sodium bisulphate. The mixture creates two gases, sulphur dioxide, and chlorine gas, the latter of which is toxic and is believed to have been responsible for the injury.
This scenario shows the importance of storing potentially hazardous materials appropriately. Risk assessments need to be completed in order to make sure that there is no cross contamination of substances such as this causing possible risks to health of people who visit the gym and the employees who work there.
The Occupiers Liability Act 1957 provides that an occupier of premises owes a common duty of care to all visitors to his premises . The standard to which the owner of the premises must comply with is that any visitors must be “reasonably safe in using the premises for the purposes for which he is invited to be there”. It appears that the gym may have fallen below these standards if they are found to have failed to store these products safely and correctly.
