In Watt v Hertfordshire County Council [1954] 1 WLR 835, a fireman was injured in a fire engine on the way to answer an emergency call (a woman was trapped under a lorry). The lifting equipment required to deal with the emergency was being carried but had not been properly secured in transit. It was held that there was no breach by the firemen’s employer, as the risk of injury was small and the ultimate aim of saving life justified taking the risk.
