053-8 Wyo. Code R. § 8-1
(a) Portable boiler used for rig heating shall be constructed, installed, operated, inspected and repaired to conform to the Engineering Standards of ASME Boiler and Pressure Vessel Code, Sections I and VIII- 1971.
(b) All boilers, while in operation, shall be under the supervision of a competent crew member.
(c) If any defects are found in a boiler or appurtenant equipment, the equipment operator in charge shall be notified immediately by the boiler operator and immediate corrective action taken.
(d) The safety pressure relief valve and discharge end of exhaust pipes leading from boilers shall be located or placed in such a way as to prevent discharge from being released to the atmosphere where injury to any person or property may result.
(e) Steam boilers shall be located at least 120 feet from the well bore when hydrocarbons or other volatile substances are in the well. (They should be located on the prevailing upwind side of the rig.)
(f) Each boiler shall be equipped with safety pressure relief valves set at a pressure not to exceed the working pressure of the boiler.
(g) Fuel valves shall not be located in front of the fuel burner, thus reducing potential of a burn in case of a flash-back.
(h) Ample lighting shall be provided so that water levels can be easily read.
(i) Boiler flues shall be kept reasonably clean at all times.
(j) Reclaimed water used in a boiler shall not be contaminated with crude or other oils.
(k) There shall be no valve at the discharge opening of a safety pressure relief valve, nor in the discharge pipe connected thereto.
(l) The safety pressure relief valve shall be connected as close to the boiler steam area as possible, with no valves and minimum piping between the safety pressure relief valve and the boiler.
(m) The piping on the discharge side of the safety pressure relief valve shall be properly secured and shall contain no valves.
