Lynda Wilkins was killed in an explosion at the company鈥檚 plant in Chorley

BAE systems has been fined 拢80,000 following an explosion which killed a worker in Lancashire.

The Health and Safety Executive (HSE) prosecuted BAE Systems Land Systems (Munitions and Ordnance) following Lynda Wilkins鈥 death at the company鈥檚 explosives plant on Central Avenue in Chorley.

Wilkins was working with lead styphnate, a sensitive primary explosive, when she was killed in March 2005, a Liverpool Crown Court heard.

The exact cause of the explosion remains unknown as Wilkins was working alone, the HSE said.

An HSE investigation found that the company allowed unsafe working procedures to develop by providing too little supervision and monitoring.

BAE Systems pleaded guilty to breaching the Health and Safety at Work etc Act 1974 by failing to ensure the safety of its employees.

It was ordered to pay 拢118,000 towards the cost of the prosecution, in addition to the fine, at Liverpool Crown Court on 14 January 2010.

HSE inspector Colin Hutchinson said: 鈥淭his was a tragic incident and my sympathies go to Lynda Wilkins鈥 family. Although we have been unable to conclude what caused the explosion, it is clear that BAE Systems鈥 failings contributed to her death.

鈥淭he substance she was using is known to be extremely sensitive and must be handled carefully. BAE Systems failed to ensure the process was properly supervised and monitored.

鈥淓xplosives companies must learn from this incident by making sure their safety procedures are both sufficient and rigidly followed to avoid needless loss of life in the future.鈥
