Warwick Crown Court heard that a complaint was raised in August 2014 against Abel (UK).

An HSE investigation found the company was selling paint stripper containing dichloromethane (DCM), which is restricted under Registration, Evaluation, Authorisation and restriction of Chemicals (REACH).

The company also failed to check at the point of sale the paint stripper containing DCM was either being sold for use in industrial installations or, after October 2016, to appropriately certificated professionals, which is a condition of sale.

HSE worked with online platforms to have the advertisements for these products taken down and served enforcement notices to prohibit further supply.

But the enforcement notices were ignored by Abel (UK) ltd.

Abel (UK) Ltd’s director, Nicholas Corbett of Nuneaton pleaded guilty to breaching safety regulations and was given a 10-month custodial sentence.

Speaking after the hearing, HSE inspector Sarah Dutton said: “Chemicals are carefully regulated to protect human health and the environment.

“Dichloromethane (DCM) has been restricted in paint strippers due to concerns for human health during its use – it has caused fatalities when not used properly.

“Companies should be aware that HSE will take robust action against those who unnecessarily put the lives of workers and the public at risk, and against those who endanger the environment, through the inappropriate supply and use of chemicals.”
