Sections

26-8. General Requirements.

Ground Support Systems

A Qualified Person (QP) must design or review all ground support and excavation systems.
Provide suitable protection for employees from loose ground during the installation of these systems.

Hoisting

Hoist ways can hoist either materials or personnel, but not both at the same time.

Material Handling Equipment

Equip vehicles and mobile equipment with a visible revolving, flashing amber light and ensure it's operational during use.
Equip haulage equipment with headlights, a back-up light, and an automatic back-up alarm. Secure tracks for narrow-gauge railroads and use automatic safety couplings and positive locking devices on locomotives and mine dump cars.
Operate haulage equipment safely, maintain a clear line of sight during load dumping, and separate non-work vehicles from construction activities.

Waterborne Safety and Flood Prevention

Ensure water discharged from sites meets EPA NPDES and local authority requirements. Test water for hazards to keep exposure below OELs.
Implement measures to prevent flooding near water sources and equip personnel in wet underground areas with appropriate protective gear.

Compressed Air Work

Perform work in compressed air environments in compliance with 29 CFR 1926.803, including developing a CAWP as specified.

EM 385-1-1 Paragraph 26-8 (e.–i.).

26-8. General Requirements. (e.–i.).

e.  Ground Support Systems.  A QP must design or review all ground support systems, shoring, roof support systems, excavation methods, and rock bolt support systems. Provide suitable protection for employees exposed to the hazard of loose ground while installing ground support systems.  (26-8.e)

f.  Hoisting.  Hoist ways may be used to hoist materials or personnel, but not both simultaneously.  (26-8.f)

g.  Material Handling Equipment.  (26-8.g)

(1)  Mount a revolving, flashing amber light on all vehicles and mobile equipment required to move in and out of underground construction areas.  Mount the light so that it is visible in all directions and must be operational whenever the vehicle or mobile equipment is in operation.

(2)  Equip haulage equipment with two headlights at both ends, a back-up light, and an automatic back-up alarm.

(3)  Where narrow-gage railroads are used for haulage, the tracks must be secured to prevent shifting.  No “humping” of mine dump cars will be permitted.

(4)  Locomotives and mine dump cars must be equipped with automatic safety couplings, and cradle cars must be equipped with a positive locking device to prevent accidental dumping.

(5)  Do not operate haulage equipment at a speed that will endanger any employee.

(6)  Operators must ensure that a clear line of sight exists to the entire area where a load will be dumped, directly or via a spotter that has coordinated clearance requirements and communication methods with the operator before dumping loads.  All other personnel must remain clear of this area until dumping is completed, and the operator signals that access can be resumed.

(7)  Keep vehicles not directly involved in work away from portals and separated from construction activities.

(8)  Conveyors used to transport muck from tunnels must be installed, guarded, and maintained according to chapter 14.  Provide fire extinguishers or equivalent protection at the head and tail pulleys of underground belt conveyors and at 300 feet (91.4 m) intervals along the belt line.

h.  Waterborne Safety and Flood Prevention.  (26-8.h)

(1)  Water discharged from any underground or construction site must be tested and treated to ensure that it meets EPA NPDES and local authority discharge requirements, as appropriate.

(2)  When the potential exists, water must be tested to ensure that it contains no hazards that may expose workers above any OELs according to chapter 6 of this manual.

(3)  Take measures to prevent flooding whenever openings are located adjacent to sources of water that may cause flooding in the underground work area.

(4)  Personnel working in wet underground areas must wear rubber boots and rain gear, as necessary.

i.  Compressed Air Work.  Perform work in compressed air environments according to 29 CFR 1926.803 (29 CFR 1926 Subpart S), to include development of a CAWP according to paragraph 26-7.b.  (26-8.i)
