Margate Magistrates Court is set to hold the prosecution of a trader from Kent who is accused of putting vulnerable people at risk of carbon monoxide poisoning.
Tommy Smith, who faces a possible fine of £11,000 if found guilty, allegedly targeted the elderly and vulnerable in the Thanet area of Kent, situated on the northern tip of the county.
The Health and Safety Executive and Kent County Council Trading Standards believe that Mr Smith reduced the height of two chimneys, both of which contained gas boiler flues, thus giving rise to the risk of a build up of carbon monoxide.
He is accused of breaching of Regulation 8(1) of the Gas Safety Regulations 1998.
Carbon monoxide is both colourless and odourless and, as a result, can be very hard to detect.
It can build up to dangerous concentrations indoors when fuel-burning devices are not properly vented, maintained or operated.
