The Fuel Injection Test Bench Safe Operating Procedure (SOP) sets out how to manage the risks of testing fuel pumps and injection equipment on a test bench, from the hazards and precautions to a numbered operating procedure.
It covers the hazards (noise, electricity, hot parts, air and fluid under pressure, hazardous vapours, manual handling and poor housekeeping), the PPE to wear, operator training, the pre-operational inspection, what to always do and never do, and maintenance under lockout/tagout.
A hazard checklist for powered non-mobile plant, with Y, N and NA for each item, helps confirm every safety measure is in place.
