A housing association maintenance company has been fined £400,000 after an employee died from inhaling toxic vapours from flooring adhesive.

Darren Nevill, 38, was working for Connect Property Services Limited laying a vinyl bathroom floor at a domestic property in Hoddesdon, Hertfordshire on 9 December 2020.

His employer purchased an adhesive containing Dichloromethane (DCM), a highly volatile solvent. Small volumes will give off large amounts of colourless, low odour vapour, even at room temperature. He used this regularly during his employment.

On the day of his death, the hose to the pressurised glue canister became damaged, releasing a large amount of adhesive into the poorly ventilated bathroom. Mr Nevill lost consciousness and collapsed. Emergency services had to force entry to the bathroom to reach him.

An investigation by the Health and Safety Executive (HSE) found that Connect Property Services Limited, of Ealing Gateway, 26-30 Uxbridge Road, London, had failed to take appropriate precautions to ensure substances hazardous to health are not used when safer alternatives are available.

HSE guidance on Dichloromethane (DCM) states to avoid the use of DCM-based products whenever reasonably practicable, by using suitable and safer alternative products or methods. DCM-based products should only be used in well-ventilated areas, to prevent the build-up of vapour. Examples of poorly ventilated areas can include bathrooms, cellars, stairwells and sheeted enclosures.

The company pleaded guilty to breaching Section 2(1) of the Health and Safety at Work etc Act 1974. At Stevenage Magistrates Court on 26 January 2026, Connect Property Services Limited was fined £400,000 and ordered to pay costs of £9676.81 with a surcharge of £190.

Prosecutor Jon Mack told the court “HSE scientists calculated that the statutory 15-minute exposure limit for DCM would have been reached within 2-13 seconds, and the final concentration in the bathroom at the time of Mr Nevill’s death would have been 84.5 times the exposure limit. Mr Nevill was found to have three times the fatal concentration of DCM.”

Speaking after the hearing, HSE inspector Rauf Ahmed said: “Our thoughts today are with the family of Mr Nevill, who was just setting out on his career in construction. He should have returned home safely to his family at the end of his working day but, because of the failings of Connect Property Services Limited, he did not.”

The HSE prosecution was brought by HSE enforcement lawyer Neenu Bains and paralegal officer Helen Jacob.

• Three-year-old girl found unconscious during swimming pool free-play session.
• Child became trapped beneath large float during holiday camp activity.
• HSE investigation found inadequate safety documentation and communication.

A company that runs holiday camps for children across the country has been fined £6,000 after a three-year-old girl nearly drowned during a swimming pool free-play session.

The incident occurred on 26 July 2023 at Bishopsgate School in Egham, Surrey, where Oxford Active Ltd was running a holiday camp. The three-year-old girl was found face down in the swimming pool underneath a large float and was not breathing. Staff intervened and were able to resuscitate her.

The girl was part of a group of 19 children aged between three and five who were taking part in a free-play swimming session. Most of the children were non-swimmers, including the three-year-old. Staff had fitted her with two sets of armbands and provided her with a foam noodle before she entered the pool. A number of floats were present in the pool, including a large rocket-shaped float, beneath which the child became trapped. When she was found unconscious, she was no longer wearing the armbands or using the noodle.

An investigation by the Health and Safety Executive (HSE) found that Oxford Active Ltd’s documentation relating to pool safety and supervision was insufficiently detailed and lacked clarity. The investigation also found that the content of this documentation was not communicated effectively to staff, meaning appropriate control measures were not properly understood or implemented.

HSE guidance on swimming pool management highlights the importance of effective supervision arrangements, particularly where young or non-swimming children are involved. This includes ensuring suitable adult-to-child ratios, clear rules on the use of floats and inflatable equipment, robust risk assessments for free-play sessions, and effective emergency procedures so incidents can be identified and responded to immediately.

Oxford Active Ltd, of Oxford, pleaded guilty to breaching Section 3(1) of the Health and Safety at Work etc. Act 1974. The company was fined £6,000 and ordered to pay £12,000 in costs at a hearing at Chichester Magistrates’ Court. A victim surcharge was also applied, amounting to forty percent of the fine, capped at £2,000. In addition, £2,000 compensation was awarded to the child’s family.

After the hearing, HSE Inspector Russell Beckett said:

“It is vital that children are able to learn to swim in a safe environment and that parents can trust their children will be properly looked after while doing so.

“Fortunately, the three-year-old child recovered well, but this incident could very easily have had a tragic outcome.”

This HSE prosecution was brought be enforcement lawyer, Neenu Bains and paralegal officer, Farhat Basir.

A global chemicals company has been fined £400,000 after a worker narrowly escaped serious injury in a high-pressure steam release incident at its site in Huddersfield.

Syngenta Ltd was sentenced after the 59-year-old contractor – working under its control and direction – had been carrying out unsafe maintenance work. The man had been working as a mechanical fitter on 6 November 2023 when the incident took place, resulting in the company reporting it to the Health and Safety Executive (HSE) as a dangerous occurrence. The incident involved a release of high-pressure steam as he went about his job.

The company operates a large agrichemicals production site where some of the production plants rely on high pressure steam to manufacture products. The HSE investigation found that the incident occurred during the planned replacement of a faulty steam trap on small-bore pipework.

Steam traps are devices that automatically remove condensate (water) and air from the high-pressure steam system. There was a sudden failure of the valve used to isolate the work location from the steam, and this resulted in the uncontrolled high-pressure release.

The HSE investigation also revealed several failures with the system of work in operation. These included:

• The isolation valve failed when the mechanical fitter was separating a bolted flange by cutting the bolts using a battery powered reciprocating saw.
• The isolation valve and flange bolts were affected by corrosion and were in a poor condition.
• Due to widespread corrosion of flange bolts on the steam distribution system, it was considered necessary to routinely cut bolts rather than unscrew them using a spanner.
• Cutting flange bolts reduces the ability to control any unexpected, trapped material or pressure remaining in the pipework.

Syngenta Ltd pleaded guilty to having failed to ensure that the isolation valve and flange bolts were maintained in an efficient state, in efficient working order and in good repair – as required by Regulation 5(1) of the Provision and Use of Work Equipment Regulations 1998 (PUWER) – HSE.

In addition, there was an issue with the company’s documented risk assessment procedure in place before such maintenance work was undertaken. It was routine for Syngenta to carry out maintenance work on small-bore pipework of the high-pressure steam distribution system, using a single method of isolation.

HSE’s published guidance about on this subject (The safe isolation of plant and equipment – HSE, HSG253) emphasizes that using a method of double isolation is safer. The risk assessment documents in place failed to appreciate the increased risk involved in relying on a single method of isolation when there was known corrosion of the work equipment. Syngenta Ltd also pleaded guilty to having failed to make a suitable and sufficient assessment of the risk involved in carrying out the specific maintenance work described as required by Regulation 3(1) of the The Management of Health and Safety at Work Regulations 1999.

Syngenta Ltd, whose head office is at Bracknell, Berkshire pleaded guilty to the two offences at Leeds Magistrates’ Court on 28 January 2026 and was fined £400,000 and ordered to pay costs of £8,288.

HSE Inspector David Welsh said: “If a safe system of work had been in place at the site when the maintenance was being carried out, this dangerous incident would not have happened.

“The company did not appreciate the extent of the risk posed because of the way the maintenance work was being done, and the relatively simple control measures that could have been applied to make it safer.

“Syngenta not only failed produce an appropriate risk assessment, but also failed  to maintain work equipment in a safe condition – which taken together meant that this was a dangerous accident waiting to happen.”

This HSE prosecution was brought by enforcement lawyer Iain Jordan and paralegal officer Zara Salman.

• Worker suffered life-changing injuries after falling through fragile rooflight.
• HSE investigation found no measures in place to prevent or mitigate a fall.
• Incident highlights ongoing risks of working at height in construction.

Daniel Jenner, trading as Jenner Roofing and Building Services, has received an eight-month suspended sentence after a worker fell four metres through a rooflight to the concrete floor below.

The incident occurred on 12 August 2023, when a worker was carrying out work on behalf of Jenner Roofing and Building Services, at an industrial estate in High Wycombe, working alone to clean and repair gutters and drains.

While walking next to the unguarded edges of the roof, he approached a fragile roof covering above a service road. He stepped onto a rooflight, fell through it, and sustained serious, life-changing injuries including a fractured skull and cheekbone, a fractured leg and a broken wrist.

An investigation by the Health and Safety Executive (HSE) found that Daniel Jenner had failed to implement any work-at-height measures to prevent workers from falling from the unguarded edges of the roof or through the fragile roof itself. There were no measures in place to mitigate for either the distance or the impact of a fall.

Working at height remains one of the leading causes of workplace injury and death. HSE has detailed guidance available on working safely at height and managing construction activities that can be found on our website.

Daniel Jenner, trading as Jenner Roofing and Building Services, pleaded guilty to breaching Regulation 6(3) of the Work at Height Regulations 2005. He received an eight-month suspended sentence, was ordered to complete 280 hours of unpaid work and to pay £500 in costs at a hearing at High Wycombe Magistrates’ Court on Wednesday 21 January 2026.

HSE Lead Inspector, Sophie Neale, said:

“This was a tragic but avoidable incident, where an individual suffered life-changing injuries due to working at height. Had suitable control measures been implemented, such as fall prevention or fall mitigation measures, this incident would not have occurred.

“This prosecution highlights ongoing safety failures in the construction industry, where working at height remains one of the leading causes of workplace injury and death.”

This HSE prosecution was brought by HSE enforcement lawyer, Gemma Zakrzewski and paralegal officer, Helen Hugo.
