A furniture maker claims he has been advised to stop using a broom to sweep his factory by safety inspectors as it can cause serious harm to the health of workers.
Michael Northcroft, who says he is a furniture maker to the stars, was told by the Health and Safety Executive that sweeping sawdust was exposing his 10 workers to "a substance hazardous to health, namely airborne wood dust".
The defiant 63-year-old called the advice "a load of rubbish" and said he plans to continue to sweep his factory in Leyton, east London, as opposed to using an industrial vacuum.
Work-related lung disease accounts for 12,000 deaths per year, according to the HSE.
Mr Northcroft, who says his customers include Theresa May and Adele claims a letter told him to "prohibit" dry-sweeping and to provide evidence of compliance to the executive.
