Wallop Defence Systems Finded £376,000

Graham Marshall - Monday, December 31, 2012

Wallop Defence Systems Ltd (WDS) has been ordered to pay £376,000 in fines and costs for safety failings that caused a fatal explosion at its Hampshire (UK) factory.

Anthony Sheridan, 37, was killed from injuries sustained in the blast at WDS in June 2006.

Mr Sheridan was emptying one of six industrial ovens used in the manufacture of military flares.

The ovens contained high levels of nitroglycerin (NG) that exploded, causing an explosion that destroyed the factory building.

Several other workers were injured in the incident, with blast debris landing up to 600' away.

Winchester Crown Court heard that WDS had realized in 2004 that their process for curing pellets as part of the production of military flares produced the explosive chemical as a by-product.

An investigation by the UK HSE found that none of the company's senior management team or technical advisers were competent to deal with the NG issue, but did not seek external professional assistance.

Reviewing the company's procedures since NG was discovered in 2004, UK HSE found WDS was not complying with the basics in explosive safety and failed to adhere to licensing requirements for the storage and processing of explosive substances.

Their failure to properly assess and manage the risk put workers and the public in danger.

A second explosion occurred in December 2008 when the company attempted to dismantle the remaining NG contaminated oven on the company's second site.

No one was injured in the explosion.

The court heard that the company failed to engage with the UK HSE and seek competent expert advice on dismantling it and that the incident was entirely foreseeable and avoidable.

WDS was fined a total of £266,000 and ordered to pay £110,000 in costs for three breaches of the Health and Safety at Work Act 1974, two relating to the fatal explosion and the other to the second blast.

Speaking after sentencing, Qamar Khan, Principal Inspector for UK HSE's explosives team, said: "Anthony Sheridan suffered horrifying injuries in the explosion that caused his death. "Both this explosion and the subsequent blast in December 2008 were foreseeable and preventable had the company sought and taken appropriate advice and implemented the correct measures. If these steps had been taken Anthony Sheridan would still be alive. "It is especially concerning that despite issues with the factory being reported to senior WDS management, nothing materially changed to safeguard employees and the public. The company deluded itself that everything was OK and in hand. "Companies working with dangerous substances must take extreme care at all times and in all aspects of their operations. That clearly didn't happen here, and the consequences were tragic."
