Rule 5768.
(1)
						Subrules (2) to (16) of this rule apply only to air, gas, or mist drilling
						operations.
(2) The stripper rubber
						in the circulating head shall be inspected by a qualified employee at least
						once each tour. If any leaks are found, immediate action shall be taken to
						change out the stripper rubber.
(3)
						Pipe connections carrying gas or air to or from the wellbore shall be made up
						leak-free. Lines and connections shall be frequently inspected by a qualified
						employee and maintained free of leaks.
(4) A blooey or bleed-off line shall be not
						less than 150 feet in length or equivalent safety measures shall be taken. The
						blooey or bleed-off line shall be located downwind of the rig for the
						prevailing wind direction.
Equivalent safety measures shall be taken for other
						  wind conditions. A blooey or bleed-off line shall be laid as straight and free
						  of sags as practical from the wellbore and shall be securely anchored.
(5) In gas drilling operations, a
						shutoff valve shall be installed on the main feeder line not less than 150 feet
						from the wellhead. In air drilling operations, the shutoff valve shall be
						installed in the main feeder line near the compressors.
(6) An air compressor shall not be located
						closer to the wellbore than the nearest engine operating the rig.
(7) The compressor shall be equipped with
						safety features, such as a pressure relief valve, pressure gauge, engine
						governor, and fuel shutoff valve.
(8) When making a connection, the standpipe
						valve shall be closed and the bleed-off line shall be opened before breaking
						out the tool joint.
(9) A pilot
						light shall be kept burning at the end of the flow line at all times, except
						when making trips. The pilot light shall be turned off while making
						trips.
(10) An effective pilot
						light or other continuous lighting device shall be kept burning at the end of
						the flow line at all times during the drilling operations, except when making
						trips.
(11) Equipment and materials
						for killing the well with drilling fluid shall be at the drilling site and such
						equipment shall be operable before a drilling operation commences.
(12) One B-C fire extinguisher of not less
						than 150 pounds dry chemical capacity, or equivalent, shall be stationed on the
						job in addition to those required in
						R
						408.15715.
(13) The rig substructure shall be ventilated
						either by dependable natural convection or by use of mechanical fans which
						provide not less than 12 complete air changes per hour.
(14) A rig engine shall have an adequate heat
						and spark-arresting system for the exhaust.
(15) A gas or gasoline-fueled engine used in
						gas drilling operations shall be equipped with a shielded low-tension ignition
						system.
(16) A burning stove, open
						fire, or other possible source of ignition, such as an electric-powered tool or
						2-way radio, shall be permitted only in a designated area. Only a heater which
						is designed and approved as safe shall be permitted on or near the rig
						floor.
(17) An emergency shutdown
						device shall be provided for each rig engine, excluding the power plant, and
						shall be located at the driller's console.
