Isolation and Lock-out Workers walked through the process to Launch a cleaning tool on Line 13 including the de-energization, isolation and application of locks and tags on valves and electrical switches. An explanation of the verification step for double block and bleed (DIB) was received including the applicable scenario where DIB was not achieved and the engineer certified Alternate isolation Plan was followed. Vac truck operations were explained including the grounding method and requirement for H2S/Benzene indicators and signage. Loading Tool Workers described the requirement for gas/benzene detection, proper PPE, fire extinguishers and bonding cables and confirmation that all ignition sources are monitored at least 100 feet away from work area (vehicles, air compressor). Personnel to wear full face mask respirators when working near open trap door and front of the trap is flagged or signage installed to prevent workers from inadvertently walking or working within 15 m (50 ft) of trap. Tool is loaded with non-critical lift, however load charts are verified and rigging is inspected. Tool is loaded into trap with care taken to avoid damage to the o-ring which is cleaned and inspected prior to closing the trap door. Flooding and Pressurizing Drawings are verified for all steps including valve operation. The trap is flooded from the vac truck and valve breakers are energized. LOTO for drain and vent valves is verified to be in closed position. Valve is opened to flood and pressurize trap and the door seal and fittings are verified for no leaks. Tools is launched as per procedure CCO confirms acceptable conditions and control center is notified of time of launch.
