EM 385-1-1 Paragraph 8-8 (d.–f.).

8-8. General Requirements. (d.–f.)

d.  Tags and Labels.  (8-8.d)

(1)  Label, tag, or mark each container of hazardous material (see chapter 6).

(2)  Use accident prevention tags only as a temporary means of warning employees of an existing hazard (for example, defective tools, equipment, caution orders, tags for HEC).

(3)  Tags must contain a signal word (that is, Danger, Warning, Caution) and a major message (presented in either pictographs, written text, or both) to indicate the specific hazardous condition or the instruction to be communicated to the employee. The signal word must be readable at a minimum distance of 5 feet (1.5 m), or such greater distance as warranted by the hazard.

(4)  Identify piping systems (for example, pipes, fittings, valves, and pipe coverings) according to ASME A13.1 color scheme and directional flow requirements.

e.  Traffic Control.  Traffic control is extremely important on highways, in residential areas and at construction sites.  When traffic may pose a hazard to operations, public roads must be closed.  If passing traffic will likely be affected by a USACE mission/contract, a Traffic Control Plan appropriate to the complexity of the work must be prepared according to paragraph 8-7.  (8-8.e)

(1)  Coordinate road closings with the USACE supervisor/KO or COR and appropriate local agencies, and obtain, in writing, approval and required permits prior to closing or restricting any roads.  Contractors must keep the KO or COR appraised of any such closing as early as possible.

(2)  Conduct traffic control, traffic flagging, and signage procedures according to the MUTCD.

(3)  All barricades, warning signs, lights, temporary signals, other devices, flagmen, and signaling devices must meet or exceed the minimum requirements of this manual, applicable federal, state, and local requirements.

(4)  In construction areas, post legible traffic signs in advance of and/or at points of hazard according to the MUTCD.

(5)  Erect required barricades, and signage (for example, Danger, Warning, Detour) before closing any roads.

(6)  When roads are temporarily closed to public access, use barricades or gates that are highly visible in day or night conditions according to the MUTCD and other applicable requirements.

(7)  Post appropriate warning signs on affected roads at least 100 feet (30.5 m) before the barrier according to the MUTCD or USACE Sign Standards Manual (that is, EP 310-1-6a and EP 310-1-6b).  Size and placement of signs depend on viewing distance and speed limit of roadway.

f.  Signal and Flagging Systems, Personnel, and Procedures.  (8-8.f)

(1)  For marine signals, see chapter 19.

(2)  For LHE and helicopter hand signals, see chapter 16 of this manual.

(3)  Protect signal systems against unauthorized use, breakage, weather, or interference. Stop all work if the system malfunctions.
