Current through Register 2024 Notice Reg. No. 28, July 12, 2024
(a) Every derrick used for drilling or
					 redrilling shall have a continuous outside derrick platform at least two feet
					 (2') wide completely around the derrick at an elevation not more than two feet
					 (2') above and not more than one (1) girt [not to exceed eight feet (8')] below
					 the principal inside derrick platform.
(b) Every derrick used for drilling or
					 redrilling shall have an outside derrick platform at least two feet (2') wide
					 across the side of the derrick in which each auxiliary inside derrick platform
					 is located. This outside derrick platform shall be parallel to the longest side
					 of the inside platform and shall be two feet (2') or less from adjacent derrick
					 legs and at an elevation not more than two feet (2') above and not more than
					 one (1) girt [not to exceed eight feet (8')] below the inside platform. A
					 minimum vertical clearance of at least six and one-half feet (6 1/2') shall be
					 maintained between outside derrick platforms.
(c)
(G-3) With the exception noted below, every derrick used
						for well servicing shall have a continuous outside derrick platform at least
						two feet (2') wide completely around the derrick at an elevation not more than
						two feet (2') above and not more than one (1) girt [not to exceed eight feet
						(8')] below the principal inside derrick platform.
If well-servicing hoists are used and operating
						conditions necessitate running the sand line to the sand reel outside the
						derrick tower, the platform on that side of the derrick tower may be
						omitted.
(G-2) Every derrick used for well servicing shall have an
						outside derrick platform at least two feet (2') wide across the side of the
						derrick in which the principal inside derrick platform is located. This outside
						derrick platform shall be parallel to the longest side of the inside platform,
						and shall be two feet (2') or less from adjacent derrick legs and at an
						elevation not more than two feet (2') above and not more than one (1) girt [not
						to exceed eight feet (8')] below the principal inside derrick
						platform.
(d) (G-2, G-3)
					 Every derrick used for well servicing shall have an outside derrick platform at
					 least two feet (2') wide across the side of the derrick in which each auxiliary
					 inside derrick platform is located. This outside derrick platform shall be
					 parallel to the longest side of the inside platform and shall be two feet (2')
					 or less from adjacent derrick legs and at an elevation not more than two feet
					 (2') above and not more than one (1) girt [not to exceed eight feet (8')] below
					 the inside derrick platform. A minimum vertical clearance of at least six and
					 one-half feet (6 1/2') shall be maintained between outside derrick platforms.
Every derrick used for well servicing shall have an
						outside derrick platform at least two feet (2') wide across the side of the
						derrick in which the inside derrick rod board platform is located. This outside
						derrick platform shall be parallel to the longest side of the inside derrick
						rod board platform, and shall be two feet (2') or less from adjacent derrick
						legs and at an elevation not more than two feet (2') above and not more than
						five feet (5') below the inside derrick rod board platform. A minimum vertical
						clearance of at least six and one-half feet (6 1/2') shall be maintained
						between outside derrick platforms.
(e) (G-2, G-3) Direct access shall be
					 provided to each outside derrick platform by the main derrick ladder, by an
					 auxiliary derrick ladder from any lower outside derrick platform to which the
					 main derrick ladder provides direct access, or by extending the outside derrick
					 platform to the main derrick ladder.
(f) The outer edges of all outside derrick
					 platforms shall be equipped with standard railings and toeboards.
(g) The outer edges of all ladder offset
					 platforms shall be equipped with standard railings but need not be equipped
					 with toeboards.
EXCEPTION: to subsections (f) and (g) of this section:
						Railings and toeboards constructed on these respective platforms before March
						1, 1924, need not conform to standards set forth in the General Industry Safety
						Orders, but shall consist of a top rail three and one-half feet (3 1/2') high,
						and a mid rail, or equivalent type of construction. Such railings and toeboards
						shall be constructed and maintained to conform to good engineering
						practices.
