RC-01 Thunderbolt — LSM Cabinet Service
Launch track LSM cabinet service. Includes transfer track isolation and capacitor bank discharge. ASTM F770 maintenance.
It refers to equipment that does not exist and illustrates the elements 29 CFR 1910.147(c)(4)(ii) requires a procedure to contain. It is not a document to adopt. Under (c)(4)(i) the employer must develop and document energy control procedures specific to their own machines, and under (c)(6) must inspect them at least annually.
Other standards also apply to this work
- NFPA 70E — arc flash. Working on an energised-capable LSM cabinet requires shock and arc-flash boundary assessment and appropriate PPE.
12 points, in sequence
Transfer track drive disconnect. Upstream block - isolate so no train can be moved into the work zone.
Train chocks fitted at the station and any occupied block. GRAVITY - a train on grade will roll.
Anti-rollback dogs engaged on the lift. Prevents lift chain runback under load.
Ride main disconnect, 480V at the MCC. Feeds lift, brakes, control system and station.
LSM launch drive disconnect. Feeds the linear synchronous motor cabinets along the launch track.
LSM capacitor bank discharge point. STORED ELECTRICAL - banks hold lethal charge after the drive is isolated.
Compressed air supply at the ride header. Feeds brakes, restraints and transfer track.
Air header bleed downstream of the supply valve. Confirm zero on the gauge.
Block brake air supply. Brakes are SPRING-APPLIED and air-released - removing air sets the brakes.
Restraint hydraulic supply. Holds lap bar locking pressure; bleed before working on a restraint.
Evacuation walkway and catwalk lighting. Must REMAIN ENERGISED while anyone is on the structure.
Ride control PLC and E-stop circuit. Control circuitry only - NOT an energy isolating device.
What your site must supply
This example is structurally complete and factually generic. The things below are the things only you can know — and they are exactly what makes a procedure yours.
- Your own asset and isolation-point tag numbers. The tags shown are illustrative and refer to equipment that does not exist.
- The actual location of every disconnect, valve and vent on your equipment.
- Measured stored-energy magnitudes and the dwell time required to dissipate them.
- Your verification method for each point, and who is authorised to perform it.
- Any additional energy sources present on your equipment and absent here.
