Most gas-fired generators `at risk’

Most power station gas turbines run the risk of explosion because their acoustic enclosures are not sufficiently ventilated, the Health & Safety Executive has warned.

In a guidance note issued to advise operators of combined cycle gas turbine plants on the action needed to comply with safety laws, the executive says: `Ventilation has been found to be inadequate in a significant majority of cases, with the key requirements of dilution ventilation not being met.’

The HSE may prosecute Teesside Power over an explosion and fire inside a turbine enclosure at its 1,825MW plant.

One worker was seriously injured in the accident, which occurred when the unit was being switched from burning natural gas to liquid fuel.
