[1954] 1 WLR 835. The claimant fireman sued his employers in Negligence when he was injured by a heavy jack that had not been properly secured on his vehicle whilst attending an emergency call. His case failed because, although the employer did owe the fireman aduty of care, whether it had breach that duty depended on whether it behaved reasonably in the circumstances. In this case the circumstances were that the fire engine was being prepared for an emergency call, and it was not unreasonable that less attention was paid to matters of stowage than would have been appropriate in other situations.
