(a) Requirements:
(i) Traveling blocks shall be equipped with
				securely attached sheave guards.
(ii) Any slip hook used for lifting shall be
				equipped with a safety latch.
(iii)
				Every traveling block, hook, elevator, and elevator link or traveling equipment
				shall be reasonably free of projecting bolts, pins and parts.

				device shall be installed on all manually operated rope catheads.
(v) The key seat and projecting key on a
				cathead shall be covered with a smooth thimble or plate.
(vi) The operator of a cathead shall keep his
				operating area clear at all times. That portion of the catline not being used
				shall be kept coiled or spooled.
(vii) When the cathead is unattended, no rope
				or line shall be left wrapped on or in contact with the cathead.
(viii) A qualified employee shall be at the
				controls while a cathead is in use. He shall stop the rotation of the cathead
				immediately in event of an emergency.
(ix) No splice shall be allowed to come into
				contact with the friction surface of the cathead.
(x) Each corner of a crown block shall be
				securely bolted or welded to the mast or derrick.
(xi) When bumper blocks are attached to the
				underside of the crown beams, a safety cable or strap shall be secured along
				their full length.
(xii) Each
				finger of a finger board shall be bolted or welded to its support
				beam.
(xiii) Any counterweight
				above the derrick floor, when not fully encased or running in permanent guides,
				shall be securely anchored to the derrick by a safety chain or wire rope safety
				line.
(xiv) Wire rope used to
				connect a tong to the counter weight shall be of a sufficient
				strength.
(xv) Every drilling rig
				shall be equipped with a reliable weight indicator.
(xvi) Any weight indicator hung above the
				floor shall be secured to the derrick by means of a wire rope, safety cable or
				chain.
(xvii) Every test plug used
				above the derrick floor shall be attached to the elevator links by safety cable
				or chain.
(xviii) The operator
				shall not leave the brake without tying the brake down or securing it with an
				adequate counterbalance unless the drawworks are equipped with an automatic
				feed control. (See exception to this rule at
Chapter 5, Section l.(a)
				(vii) (C))
(xix) The
				operator shall not engage the rotary clutch until the rotary table is clear of
				personnel and material.
(xx) The
				operator shall not leave the controls while the hoisting drum is in motion,
				except when drilling. (See exception to this rule at
Chapter 5, Section
				l.(a) (vii) (C))
(xxi)
				Each rotary tong shall be securely attached to the derrick or a back-up post
				and shall have a minimum breaking strength at least equal to the breaking
				strength of the cable.
(xxii) Any
				wire rope connections used to attach safety cables to the derrick or back-up
				post shall have a minimum breaking strength at least equal to the breaking
				strength of the cable.
(xxiii) If
				lubrication fittings are not accessible with guards in place, machinery shall
				be stopped for oiling and greasing.
(xxiv) The drawworks shall not be operated
				without all guards in position and properly maintained.
(xxv) All air compressors shall have at least
				one (1) air pressure regulator to control proper air flow.
(xxvi) The safety relief valve (safety
				pop-off) on the main air tank shall be checked periodically and kept in proper
				working order.
(xxvii) All valves
				and pressure control devices shall be kept in proper working order.
(A) There shall be no valve in the discharge
				opening of a safety pressure relief device or in the discharge pipe connected
				thereto.
(B) The piping connected
				to the pressure side and discharge side of a safety relief device shall not be
				smaller than the normal pipe size openings of the said device.
(C) The piping on the discharge side of the
				safety relief device shall be securely tied down.
(D) The piping from the discharge side of the
				safety relief device shall be sloped in order to drain liquids.
(xxviii) Hydraulic pressure lines
				shall not be subjected to pressures exceeding those recommended by the
				manufacturer.
(xxix) The brakes,
				linkage and brake flanges of the drawworks shall be checked each day.
(xxx) A mud box or other effective means
				shall be provided on all rigs to convey any fluids away from the derrick floor,
				while pulling drill stem tests or breaking wet joints.
(xxxi) Hoses, lines or chains shall not be
				permitted to come into contact with the rotary table while it is in
				motion.
(xxxii) When visibility on
				the rig floor is obscured, no worker shall be required or permitted to work on
				the rig floor while the rotary table is in motion.
(xxxiii) [Reserved]
(xxxiv) A blunt smooth-edged divider to
				separate the first wrap of a line on a cathead shall be installed on all
				manually-operated rope catheads and the clearance between the device and the
				friction surface of the cathead shall not exceed one-fourth (1/4)
				inch.
(xxxv) The friction surface
				and flanges of a cathead on which a rope is manually operated shall be smooth
				and the diameter of the cathead between the flanges shall be uniform throughout
				its length with an allowable tolerance of three-eighths (3/8) inch.
(xxxvi) Hydraulic tong control mechanism.
(A) The control device on power tongs shall
				be designed or guarded to prevent accidental activation.
(xxxvii) Pull-back post. A kelly pull-back
				post with attached snatch block to a sheave, roller or similar device (onto or
				through which is run the pull-back rope), shall be provided for pulling the
				kelly back to the rat hole. The pull-back post shall be secured either to the
				derrick foundation side sills or floor sills, and shall not be attached to or
				in contact with the derrick legs, girts, or braces.
(xxxviii) Whenever drill pipe, drill collars
				or tubing are racked in the derrick, provisions shall be made for the complete
				drainage of any fluids or gases in the stands.
