Summary
An investigation into a contact-tower fire during hot bolting describes a hammer breaking a grease fitting, releasing pressurised natural gas that ignited at a line heater. It examines missed hazards in the task-specific JSA, records firefighting and isolation actions, and recommends evaluating feasibility and depressurising equipment before bolting.
