				at the controls shall control the access and activities of personnel on the
				drilling floor while equipment is rotating, or shall stop such equipment from
				rotating until there is no danger to personnel from such rotating
				equipment.
(D) When the
				rotary table and/or kelly bushing are in motion, all hoses, lines, and other
				such entangling material in use, with the exception of spinning chains, shall
				be controlled to the extent that the loose end of the material shall not be
				closer than six (6) inches of the kelly bushing.
(E) The spinning chain shall not be wrapped
				around the joint of pipe in the mousehole, nor shall it be handled on the
				drilling floor within twenty four ( 24) inches of the rotating parts of the
				rotary table, kelly bushing or kelly.
(F) Drilling rigs which use rotary table and
				kelly bushing guards need not comply with (D) and (E) above.
(viii) Machinery shall not be
				operated without all guards properly maintained and in position, except during
				maintenance, repair or rigup work, when limited testing may be performed by a
				qualified person.

				protective devices shall be replaced and proper personnel notified when
				maintenance is complete.
(xii) All
				tools and equipment used by employees shall be in safe condition.
(xiii) Electric tools shall be grounded by

(xvi) Maintenance personnel on a contract
				basis shall abide by all safety rules and regulations pertaining to oil and gas
				well drilling.

				operating condition.
(xviii) All
				rigging shall be in accordance with recognized safe practices.
(xix) All winch lines, anchors, snatch

				signs shall be conspicuously posted to locate emergency equipment.
(xxiii) Containers of poisonous, toxic,
				flammable and/or explosive material shall be properly labeled and appropriately
				stored according to content.
(xxiv)
				(For cylinders used in welding, cutting, and brazing operations,
see
				Chapter 5, Section
				2
.) Compressed gas cylinders shall
				be stored in a well-protected, well-ventilated location, at least twenty (20)
				feet from combustible materials. Assigned storage spaces shall be located where

				in place.
(xxv) No
				material used for cleaning shall have a flashpoint less than 100°F

				(37.8°C) are Gasoline, Naphtha, etc.
(xxvi) An emergency stop device shall be
				provided for each traveling block by the use of an automatic stop device and/or
