The HSE prosecuted Faltec Europe Limited in relation to both incidents, following an investigation.
Five people fell seriously ill following the Legionnaires’ disease outbreak and one worker suffered serious burns from the explosion incident.
Newcastle Crown Court was told that between October 2014 and June 2015, two employees, two agency workers and a local resident fell seriously ill with Legionnaires Disease. HSE found the illness was caused by Faltec’s failure to effectively manage its water cooling systems within the factory, causing the legionella bacteria within the water supply to grow to potentially lethal levels.
In relation to the explosion incident, the same court heard that on 16 October 2015, an operator attempted to recover a part that came off production rollers at the plant in Boldon. There is an explosive atmosphere within the machine during normal production. The part he was retrieving came into contact with an electrostatic grid, which created a spark and caused a dust explosion.
The 19-year-old man suffered first degree burns to his face and arms. HSE found that adequate measures were not put in place to protect operators from explosion risks; this was despite previous explosions having occurred.
Concerning the legionella incident, Faltec Europe Limited of Didcot Way, Boldon in Tyne and Wear pleaded guilty to breaches of Section 2 (1) and 3 (1) of the Health and Safety at Work Act 1974 (HSWA) and was fined £800,000.
In relation to the explosion, the company pleaded guilty to breaching Section 2 (1) of HSWA and was fined £800,000. The company was also ordered to pay costs of £75,159.73 and a victim surcharge of £120.
Speaking after the hearing, HSE inspectors Fiona McGarry and Michael Kingston said: “The explosion and outbreak of Legionnaires’ disease at the Faltec factory had a major impact on the six people affected, with some suffering long-term ill-health as a result. In addition, the incidents raised concern amongst other employees and the local community.
“Supported by colleagues from Public Health England and South Tyneside Council, HSE investigated and identified breaches in both cases. In pleading guilty to three charges under the Health and Safety at Work Act 1974 the company have acknowledged these breaches.”
