Wyoming Administrative Code › Agency 053 - Workforce Services, Department of › Sub-Agency 0012 - OSHA - Oil & Gas Well Special Servicing › Chapter 8 - MOBILE PUMPING OPERATIONS › Section 8-2 - Acidizing and Fracturing

Current through July 13, 2024
(a) A check valve
				shall be placed in the discharge line as near the well bore as possible to
				prevent flowback from the well.
(b)
				All blending equipment used in fracturing operations with flammable and/or
				combustible fluids shall be grounded to a conductive rod driven into the
				ground, and all sand hauling equipment unloading sand into the blender
				hopper(s) shall be electrically bonded to the blender(s).
(c) All supercharged suction hoses shall be
				covered with hose covers to deflect fluids when pumping flammable and/or
				combustible fluids.
(d) A
				pretreatment test on pump discharge lines shall be made at least 1,000 psi over
				the maximum expected treating pressure specified by the well operator for his
				well equipment.
(e) All valves in
				discharge lines shall be checked to see that they are open before beginning to
				pump.
(f) During operations each
				employee designated to handle the pumping shall remain constantly at his
				designated station while the pump is in operation, unless relieved by an
				authorized employee as directed by the special services supervisor on that
				job.
(g) All personnel shall be
				stationed at least 75 feet from the well bore during pumping operations.
				Authorized personnel may enter for periods of short duration except during
				critical phases such as: pressuring up for line testing and loading the
				hole.
(h) All acidizing and
				fracturing equipment that could produce a source of ignition, such as internal
				combustion engines, sparks and/or electrical charges, open flames, static
				charges, etc., shall not be permitted within 75 feet of an atmosphere that is
				within 10 percent of the lower explosive/ flammable limit or greater. Sources
				of such ignitible vapors include, but are not limited to, the well bore, tanks,
				tubs, etc. When terrain, location or governmental requirements do not permit
				sources of ignitible vapors being the required distance, a closer distance may
				be used when such sources of ignitible vapors are controlled through the use of
				either inert gas blankets, physical barriers or venting 75feet downwind from
				sources of ignition or any combination of such controls.
(i) Unauthorized persons shall remain at
				least 75 feet from all pumping operations and pressure testing
				operations.
(j) All flammable
				and/or combustible fluid spilled on location shall be covered with soil before
				pumping operations begin.
(k)
				Treating pressure shall not exceed the equipment's maximum safe working
				pressure.
(l) When pumping a
				flammable and/or combustible fluid, all electrical or internal combustion
				equipment, and all fires, within 75 feet of the well bore, not used for the
				performance of the job, shall be shut down or off during treatment.
(m) Flammable and/or combustible fluids shall
				not be bled back into open measuring tanks on equipment designed for
				pumping.
(n) All spilled oil or
				acid shall be covered or properly disposed of after breakout with adequate
				precautions taken to prevent contact of personnel with such material.
(o) All fracturing and acidizing pumping
				operations involving flammable and/or combustible fluids shall be completed
				within daylight hours.
(p) The
				fracturing and acidizing operator or his designated representative shall
				conduct a safety meeting with all involved personnel prior to beginning
				treating operations.
(q) All
				discharge lines shall be placed so as not to be under any mobile equipment nor
				shall any mobile equipment be placed over any such lines.
(r) No person shall be permitted to stand
				astraddle or to step over pressurized discharge lines which originate from
				positive pressure displacement pumps.
(s) Hammering a union on pressurized
				discharge line is prohibited.
