I’ve long believed that knitting is a rather odd pursuit. I learnt in childhood that the results rarely justify the hours of effort: misshapen Christmas presents and unwanted scarves still litter cupboards at home. However, I didn’t believe that knitting was actually dangerous. It seems that I was wrong. As a result of a recent Supreme Court decision we now know that knitting – at least on an industrial scale – can cause hearing loss. The Supreme Court appeal concerned the liability of employers in the knitting industry of Derbyshire and Nottingham for hearing loss that employees suffered during the years prior to 1 January 1990 (being the date when the Noise at Work Regulations 1989 came into force). The key issue for the Supreme Court Justices was whether liability could be established at common law and/or in breach of statutory duty pursuant to section 29(1) of the Factories Act 1961 in respect of an employee able to prove a noise-induced hearing loss as a result of exposure to noise levels between 85 and 90dB(A)lepd. The appeal is Baker v Quantum Clothing Group & Anor.  UKSC 17 (judgment was delivered yesterday and a report is in today’s Times and on Lawtel).
