Kulwant Singh Chatha and Satpaul Kaur Chatha failed to put adequate measures in place to control the risk of Legionella bacteria from the cooling tower on their premises. Concerns were raised by their own water treatment consultants and there were no Legionella risk assessments in place between June 2017 and February 2018.

An investigation by the Health and Safety Executive (HSE) found that the cooling tower was not being managed to control the risk from Legionella bacteria. Isher Hangers were operating a cooling tower without biocide. This failure exposed employees of Isher Hangers, as well as members of the public, to Legionellosis, which was a particular concern as Isher Hangers’ premises are in the vicinity of two major hospitals.

Kulwant Singh Chatha and Satpaul Kaur Chatha pleaded guilty to breaching section 2(1) and 3(1) of the Health and Safety at Work etc Act 1974 and were each sentenced to serve 12 weeks in prison, suspended for 12 months, and ordered to pay costs of £12,115 each, including a victim surcharge of £115.
