Hamilton Sheriff Court heard that four electricians employed by IQA Operations Group Ltd had been drilling through door transom panels to fit electric cables into each property within the block during installation of a new low voltage distribution system.

The company had identified that an asbestos survey was carried out ahead of the works starting but did not include a survey of the transom panels above each flat entrance door.

The electricians started work on the site and drilled holes in the door transom panels in all 44 flats.

The workers were not aware that the panels contained asbestos so no measures were in place to control exposure to airborne asbestos fibres.

A resident raised a concern that the panels were asbestos, work was stopped and the panels tested.

When the samples tested positive for asbestos immediate action was taken to decontaminate the flats which involved the local council making arrangements for the residents to leave their properties while the work was being done.

An HSE investigation found that IQA had failed to provide and maintain a safe system of work to identify the presence of asbestos in the transom panels and failed to carry out a suitable and sufficient assessment of risk to their employees from asbestos when carrying out cable routing work.

IQA Operations Group Ltd of Paisley was fined £6,000 after pleading guilty to safety breaches.

Speaking after the hearing, Gerry Muir HM Inspector of Health and Safety said “This incident could have easily been avoided if the company had in place a system of work to ensure that the asbestos survey it requested to be carried out covered all of the intended work areas.

“Failing to do this resulted in 44 asbestos panels being drilled into with no measures in place to control the risk of exposure to the resultant asbestos fibres.”
