Workplace (Health, Safety And Welfare) Regulations 1992
The Workplace (Health, Safety and Welfare) Regulations 1992 require that effective provision should be made to ensure that every enclosed workplace is ventilated by a sufficient quantity of fresh or purified air. Where this ventilation is provided by mechanical means the regulations require those mechanical ventilation systems to be maintained (including cleaned as appropriate) in an efficient state, working order and in good repair. Failure to carry out these duties is a breach of the regulations.
