Sample text

Gases drawn into a pipeline can exit through air valves and remain in the underground structure. Always ventilate the underground structure and use a combustible gas and low-oxygen detector before entering the structure. Consult Occupational Safety and Health Administration rules and procedures, such as the need for harnesses and ground-level supervision, in all underground work. Inspection When inspecting air valves, isolate the valve by closing the shutoff valve before putting hands and fingers into the valve outlet.
