The researchers who produced the independent report into the circumstances surrounding the ICL/Stockline disaster welcome the call by Prospect, the trade union which represents Health and Safety Executive employees, for a full public inquiry. We specifically note, welcome and support the Prospect view that: 1. "A public inquiry should focus on the key issues affecting the performance of the HSE in Scotland and across Great Britain, to inform any changes needed to ensure the best health and safety protection for workers."

2. "In particular the debate should not scapegoat individuals constrained by public policy but should concentrate on improving the effectiveness of the HSE."

3. "The government needs to accept responsibility for placing a greater focus on funding than effectiveness - the victims deserve nothing less."

We are alarmed at the additional points made by Prospect that "HSE has been forced to cut back on staff numbers and training, close offices and prioritise work on risks causing the greatest numbers of injuries in the workplace as it chases reductions outlined by Public Service Agreement targets. These priorities are slips and trips, workplace transport, falls from height and musculoskeletal disorders. Since 2003, HSE inspectors are under instructions to look just at these issues during inspections. Unless matters of evident concern' are raised, they cannot use their experience and discretion to look into other risks such as fire and explosion, structural safety and dangerous machinery".

We share Prospect's concerns about these serious and damaging developments since 2003, affecting the capacity of HSE inspectors to carry out all necessary risk assessments in workplaces they visit, and believe such matters should be addressed fully in a public inquiry The HSE has stated in a letter to us that it expects the inquiry into the ICL/Stockline explosion to "promote transparency and build confidence in the HSE's investigative process". The only way this aim can be met is if the inquiry includes a full and transparent investigation into the role of the HSE in Scotland. Tor this to be achieved, the inquiry due to be announced by the Lord Advocate before the end of this month must be led by a senior Scottish judge.
