The charge burned for about 10 seconds sending flames and gases out of both ends of the ‘charge’ until it burnt out. The room where the ignition occurred was set on fire. Also present in that room were four explosives charges and a large “Vulcan” rocket motor, there was also a further 230kg of explosive charges in the magazine that is next door to the room, which still had the magazine doors open. Two employees were working in the room and an agency worker was present in the magazine when the ignition occurred. It was foreseeable that other propellants and charges in the room and magazine could have been ignited by the Titus charge and subsequent fires.
At the time of the incident the company did not know what explosives were in the building and could not inform the emergency services as to the level of risk. The potential to cause harm was great due to excessive explosives material being present in the building and the number of people present nearby including the emergency services.
It took the company well over an hour for the them to understand the hazards present and react to the situation, The on-site emergency plan was not made available to the Fire and Rescue Services, meaning they were put at risk.
The investigation by the HSE found that there was a lack of risk assessments and no safe system of work in place. The emergency plan was not implemented.
