Wyoming Administrative Code › Agency 053 - Workforce Services, Department of › Sub-Agency 0011 - OSHA - Oil & Gas Well Drilling › Chapter 8 - SPECIAL SERVICES AND OPERATIONS › Section 8-4 - Safety Procedures for Air and Gas Drilling

Current through July 13, 2024
(a) Specific
				Requirements.
(i) Drilling compressors (air
				or gas) shall be located at least 125 feet from the well bore and in a
				direction away from the discharge or blooie line.
(ii) The air or gas discharge line (blooie
				line) shall be laid in as nearly a straight line as possible from the well
				bore. It must be at least 150 feet in length. This discharge line shall be
				securely coupled and anchored to prevent movement. It should be laid into a
				discharge pit in such direction from the well bore as to allow prevailing winds
				to carry produced or circulated gas away from the rig.
(iii) A pilot flame shall be maintained at
				the end of the discharge line at all times when air, gas or mist drilling is in
				progress.
(iv) All combustible
				material shall be kept at least 100 feet away from the discharge line and
				pit.
(v) The air line from the
				compressors to the standpipe shall be of adequate strength to withstand at
				least e maximum dice pressure of the compressors used, and shall be checked
				daily by the compressor operator for any evidence of damage or
				weakness.
(vi) All cars, trucks,
				house trailers, etc., shall parked at least seventy-five (75) from the well
				bore, except when delivering equipment or supplies.
(vii) Smoking will not be allowed within
				seventy-five (75) of the drilling rig while drilling with gas.
(viii) A meeting with each crew, including
				all supervisory personnel, shall be held prior to drilling with gas or air. The
				rules contained herein shall be explained.
(ix) One (1) or more employees on site shall
				be shown and taught how to use the emergency shut-off equipment during gas
				drilling.
(x) One (1) or more
				employees on site shall be shown and taught how to use control units to the
				blowout preventer and all fire fighting equipment.
(xi) All pipe connections carrying gas or air
				to or from the well bore shall be made up tightly. All lines and connections
				shall be frequently checked for leaks.
(xii) In the case of gas drilling, a shut-off
				valve shall be installed on the main feeder line at least 150 feet from well
				bore. In the case of air drilling, the shut-off valve shall be in the main
				feeder line located near the compressors.
(xiii) Then making a connection, the
				standpipe valve shall be closed and the bleed off line shall be open before
				breaking tool joint.
(xiv)
				Compressors shall have such safety features as safety pressure relief valves,
				pressure gauges, engine governors, and fuel shut-off valves.
(xv) Equipment and materials for killing the
				well with mud should be on hand and operable before drilling
				commences.
(xvi) One ( 1) Class B-C
				fire extinguisher of at least 150 pounds dry chemical capacity or equivalent,
				shall be stationed on the job site in addition to the four ( 4) fire
				extinguishers as required in
Chapter 3, Section
				4. d.(9)
of these rules.
