Canada Oil and Gas Drilling and Production Regulations (C.R.C., c. 1517)

84 (1) No person shall smoke

• (a) on any rig, derrick or any derrick house;

• (b) within 75 feet of any drilling rig, well or any equipment used for the storage, measurement, separation, pumping, transfer or processing of any oil and gas where oil or gas may be present.

(2) No fire shall be located less than 75 feet from any drilling rig, well or from any equipment in which ignitable vapours are contained.

(3) Any fire that is set shall be safeguarded by mechanical or other means so that no hazard to surrounding property is created.

(4) All waste material shall be burned in a manner so as not to create a fire hazard to wells, tanks or other equipment containing ignitable vapours or disposed of in such a manner so as not to pollute any stream or fresh water stratum.

(5) No heating or lighting apparatus involving the use of a flame or exposed electrical element shall be brought into a drilling rig doghouse.

(6) No stove, open flame heater or electric heater with exposed elements shall be used within 75 feet of any drilling rig, well or of any equipment in which ignitable vapours are contained.

(7) Steam boilers or open flame steam generators shall be located at a point not less than 150 feet distant from a well or any equipment containing ignitable vapours and on the side from which the prevailing wind blows.

(8) On all internal combustion engines on a derrick floor or in a drilling engine room or within 75 feet of any equipment containing ignitable vapours

• (a) the exhaust systems, where the temperature of the parts in contact with hot gases exceeds 400°F, shall be thermally insulated and covered by metal so that no liquids can be absorbed by the insulating materials;

• (b) engine air inlets shall be fitted with flame arrestors if located within 40 feet of a well head and the final engine exhaust to atmosphere shall be fitted with a flame trap if situated within 40 feet of the well head unless otherwise directed by the Oil Conservation Engineer;

• (c) the exhaust pipes shall be directed away from the well or any equipment containing ignitable vapours; and

• (d) the manifolds shall be shielded to prevent contact with liquids which might fall thereon.

(9) The cylinders, valve chests and other hot exposed parts of steam engines and steam pipes on a derrick or in a drilling engine room or within 75 feet thereof, whenever the steam temperature exceeds 400°F, shall be fitted with thermal insulation and the insulation shall be covered by metal so that no liquid can be absorbed by the insulating materials.
