053-8 Wyo. Code R. § 8-1
(a) A pressure test on pump discharge lines when squeeze cementing shall be made at least 1,000 psi over the maximum pressure specified by the well operator for his well equipment.
(b) All valves in discharge lines shall be checked to see that they are open before beginning to pump into the well.
(c) 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 supervisor on that job.
(d) Unauthorized persons shall remain at least 75 feet from all pumping and pressure testing operations.
(e) Cementing pressure shall not exceed the equipment's maximum safe working pressure.
(f) No person shall be permitted to stand astraddle of, or to step over pressurized discharge lines.
(g) Hammering a union on a pressurized discharge line is prohibited.
(h) Overhead cementing lines shall be secured by a chain or wire rope to a location independent of the cementing system. Such chain or wire rope shall be of sufficient strength to support the anticipated load.
(i) All air compressors, while in operation, shall be under the control of an authorized employee.
(j) Any defects that affect the safe operation of the air compressors, receiver tank and/or appurtenant equipment shall be immediately reported to the equipment operator in charge for immediate corrective action.
(k) Each air compressor and receiver tank shall be equipped with a safety pressure relief valve(s) which shall not be set at more than 20 percent above the maximum working pressure as established by the vessel's manufacturer. (See Chapter 1, Section 2. , for definition of "working pressure".)
(l) The safety pressure relief valve and discharge end of vent pipes leading from air compressors, and receiver tanks if present, shall be located or placed in such a way as to prevent discharge from being released where injury to any person may result.
(m) Safety pressure relief valve(s) shall be visually inspected prior to each site use by the equipment operator.
(n) Adequate lighting shall be provided so that the gauge(s) can be easily read.
(o) Fittings and pipe shall be properly installed and shall be capable of withstanding the discharge pressure of the compressor used.
(p) There shall be no valve in the discharge opening of the primary safety pressure relief valve nor in the discharge pipe connected thereto.
(q) All air compressors shall have at least one (1) pressure control for proper air flow.
(r) Pneumatic bulk materials tanks shall not be operated at pressures higher than the maximum working pressure, which shall be indicated on all pneumatic bulk material tanks.
