Summary
A new, incorrectly selected pressure gauge leaked steam when its safety seal failed during recommissioning. A lookalike percentage gauge had been retained locally after an ordering error and installed instead of a pressure gauge. Recommendations address stores organisation, returning unused equipment, functional checks before installation and rationalising redundant gauges.
