(a) General Requirements.
(i) Every scaffold, stage, walkway, working
				platform, stairway and ladder, whether temporary or permanent, shall be
				constructed and maintained in safe condition and shall not be altered or moved
				while in use.
(ii) Work areas shall
				be kept clean and free of debris.
(iii) Walkways, stairways and exits shall be
				kept clear to provide unimpeded ingress and egress at all times.
(iv) Safe ingress to, and egress from, all
				work areas shall be provided.
(v)
				Every stairway, ladder, ramp, runway, floor and platform shall be kept
				reasonably free of objects and substances which may create a slipping or
				tripping hazard, or prevent or hinder the escape of workmen in an emergency.
(A) Standard railing shall be provided on the
				open sides of all exposed stairways and stair platforms with four or more
				risers.
(vi) With the
				exception of exit and entrance openings, and loading and unloading areas,
				standard railing with midrail, and four (4) inch toe-board shall be installed
				at the outer edge of any floor, platform, walk-way, ramp or runway which is
				four (4) feet above the ground, or another floor or working level. Where
				railings are not feasible, chains or cable of suitable strength may be used.
(A) A standard railing shall not be used for
				other than personnel protection purposes. For definition and construction
				requirements of a standard railing, refer to Subpart
D of the State of
				Wyoming Occupational Health and Safety 1910 - General Rules and
				Regulations.
(B) A
				guardrail used and/or needed for the purpose of actual or potential containment
				of equipment or material shall be of such construction and strength as to
				effectively contain the full load or stress which may be anticipated to be
				applied upon it. (For example, if twenty-five (25) pieces of six (6) inch pipe
				are contained by a guardrail, or any attachment to the guardrail, such
				guardrail and attachment must be capable of safely holding that quantity of
				pipe, plus an additional allowance for at least two (2) employees, assuming 200
				pounds per employee).
(vii) A stabbing board shall be provided for
				and used by personnel when working above the derrick floor while running casing
				or tubing.
(A) A stabbing board shall consist
				of at least one (1) three (3) inch by twelve (12) inch number one fir plank or
				metal of at least the same width and strength. If wood is used, expanded metal
				or a cable shall be fastened to the underside of the plank along its full
				length, and each end of the stabbing board shall be fastened to the derrick
				with a wire rope at least one-fourth (1/4) inch in diameter or chain of
				equivalent strength.
(B) On single
				stand rigs where there is insufficient room for twelve (12) inch wide stabbing
				boards, a special stabbing platform shall be designed which will include all
				the safety features outlined in (a) above.
(viii) A stairway shall be installed beside
				the ramps which shall extend from the ground to the derrick floor.
(ix) Every opening in a derrick floor shall
				be covered or guarded when not being used.
(x) A derrick floor, derrick walk or engine
				room floor shall not be used as a storage platform for equipment or material
				that is not required for immediate use, unless:
(A) the material or equipment is properly
				racked or stored, and
(B) does not
				cause congestion of work areas or walkways.
(xi) On all derricks, ladder platforms shall
				be installed adjacent to, and provide unimpeded access to, the fourble
				board.
(xii) Ladder platforms shall
				be located at the crown of all drilling rigs.
(xiii) With the exception of the stabbing
				board, every platform erected on the inside of a derrick shall completely cover
				the space from the working edge of the platform back to the legs and girts of
				the derrick.
(xiv) All platform
				planks shall be secured.
(xv) A
				safety cable shall be secured to the full length of the underside of each
				working platform in the derrick.
(xvi) Each mast or derrick platform shall be
				constructed, maintained and secured to the mast or derrick to withstand the
				weight of employees or other stresses which may normally be placed upon
				it.
(xvii) The board fingers and
				diving board shall be connected to their supporting beam with wire rope not
				less than one-fourth (1/4) inch in diameter, or chain of equivalent
				strength.
(xviii) Unattached tools
				or material of any kind shall not be placed in the mast or derrick above the
				floor unless there is occasion for their immediate use.
(xix) There shall be no openings large enough
				to permit a person to fall between the beams or main supports of framework of
				the crown.
