Summary
HSE alerts bulk oil and hazardous-substance storage operators to installation and testing requirements for TAV high-level switches. Test levers or plates must be correctly returned and secured to avoid apparent test functionality masking inoperative protection. The June 2010 amendment extends applicability to some single-pole, single-throw switches, depending on magnet configuration.
