R614-6-4. Industrial Railroads

Latest version.

A. Car handling and layout.

1. Purpose. These orders set up minimum standards for industrial railroads in above-ground operations. Where it has been determined by the Labor Commission that, due to the process or operation, compliance with these orders would increase the hazards, industrial railroads need not comply provided such substandard areas are properly posted with warning signs, clearance distances indicated, areas barricaded, proper instructions given to workmen or other safety devices installed to provide maximum protection to workmen. Nothing herein shall be construed as preventing the movement of material over tracks when such material is necessary in the construction or maintenance of such tracks, nor in the movement of special work equipment used in the construction, maintenance or operation of the railroad, provided such movement shall be carried on under such conditions as are necessary to provide for the safety of all concerned.

2. Definition. An industrial railroad is a railway track, or system of tracks, with necessary appurtenances thereto, owned or controlled by an industrial concern not a common carrier, which operations are conducted solely by one or more of such industrial concerns.

3. Layout. Plant layout as it applies to the installations of railroad tracks, trestles, high lines, loading docks, clearances, crossing, etc., shall comply with the Manual of the American Railway Engineering Association-Engineering Division, and General Order No. 66 of the Public Service Commission of Utah.

a. Where there is a driveway storage space or passageway under a trestle, the passageway should be protected with an overhead shield.

b. On trestles and other places where material is unloaded from side of cars, footwalk can be placed at a distance and part of the floor or walk can be arranged so that it can be lifted to allow metal or other material to fall through. Cable nets or gratings should be provided to prevent employees from falling through openings.

4. Clearance. Standard clearances may not give enough protection where tracks pass doorways or corners of buildings or other places where workers may walk directly onto tracks in front of moving railroad equipment. These locations must be safeguarded with fixed railings or other means that force employees to detour or to become otherwise alerted to the hazard.

5. Crossings. Track crossings shall be reduced to a reasonable minimum and as far as practical shall be away from buildings or their obstructions which may impair visibility. The crossings inside plants shall be equipped with stop signs, blinking light, wig-wags, gates, or other means of effective warning or be protected by a watchman, switchman, or other responsible person.

6. Trestles and Highlines.

a. Trestles shall be equipped with walks, the outer edge of which shall be at least six (6) feet from the rail.

9. Reporting bad order cars.

A definite procedure must be established for reporting bad order or damaged equipment, such as pin lifters, couplers, dumping mechanisms, etc.

10. Blocking of Cars.

a. When there is danger of cars rolling or drifting and employees are required to work on them, cars must be blocked with adequate wheel blocks to prevent them from rolling.

b. Where railroad cars are equipped with effective hand brakes, they may be set up to prevent cars from moving when employees are working on or inside of them in place of wheel blocks.

11. Blue Flag Procedure. When working on tracks, unloading or loading cars such as tank cars, gondolas, box cars, etc., the following blue flag track target procedure must be followed:

g. Train crews shall not couple into or move railroad equipment which is protected by blue flags.

h. Railroad equipment shall not be placed in front of blue flags so as to obscure them without notification to and approval of the supervisor or other person in charge of the work on the tracks. The supervisor in charge of the work will then replace the flag for proper protection.

i. The blue flags or derails are to be removed only under the direction of the supervisor or other person in charge of the work on the tracks.

j. When two or more supervisors have groups of employees working on the same tracks, each supervisor will place his own protective lock on the blue flag derail or switch.
