  • (3) In power installations

    • (a) all wiring shall be in

      • (i) rigid, threaded and vapour-proof conduit or lead covered armoured cable or aluminum-covered armoured cable, or

      • (ii) assemblies of type S cable with vapour-proof fittings if approved by the Oil Conservation Engineer; and

    • (b) all switches, control and overcurrent protective devices shall be of a vapour-proof type if fitted inside a derrick or derrick building or within 75 feet of any well, separator, crude petroleum storage or other unprotected source of ignitable vapours.

  • (4) Electric generators, motors and heaters within 75 feet of a drilling rig or well or of equipment in which ignitable vapours are contained shall be of totally enclosed construction.

  • (5) Electrical installations shall be properly maintained at all times.

Illumination of Rigs

 Lighting shall be sufficient to provide at all times for a minimum illumination of

  • (a) five foot candle power on all of the derrick floor;

  • (b) three foot candle power at the fourble board, pumps and catwalk; and

  • (c) one foot candle power at the shale shaker, stairways and other working areas.

Control of Static Electricity

 Metallic parts of containers and conductors of flammable fluids shall be in electrical contact with and connected to the ground in such manner as will prevent development of static electric charges.

Fire Extinguishers

  •  (1) Each drilling rig shall have not less than two 20-pound dry powder extinguishers and each boiler house shall have not less than two five-gallon non-freeze type fire extinguishers all of which shall be kept in good working condition.

  • (2) When a steam pressure of 100 pounds or more is used on or about any rig, there shall be placed in the derrick room thereof, apart from other snuff line, a steam hose of a diameter of not less than one inch and a length of hose of not less than 20 feet, securely connected to a steam line with the valve situated close to the exit therefrom.

Breathing Apparatus

  •  (1) Every employer shall keep on hand a sufficient number of air line respirators or other breathing apparatus all of which shall be of a type approved by the Oil Conservation Engineer.

  • (2) An employee, when working in an area where gas accumulations may present a hazard, shall use an air line mask or other breathing apparatus.

  • (3) All breathing apparatus shall be tested once in each month and the result of this test entered in a log book, or if the apparatus is provided in connection with a drilling operation, in the Rig Record Book, and the entry signed by a person authorized by the owner or operator of the apparatus.

Smoking and Fires

  •  (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.

Fuel Tanks

  •  (1) Except for the fuel tanks actually connected to the operating equipment, no storage of gaseous or liquid fuel shall be permitted within 75 feet of a well.

  • (2) Drainage from such a location shall be such that the flow is in a direction away from the location of such well.

Drill Stem Tests

 Unless a rig is adequately lighted by natural light or by means of floodlights having no electrical equipment capable of igniting gas or oil within 75 feet of the well head, no drill pipe shall be disconnected during a drill stem test unless there is no possibility of any oil or gas being present in the drill pipe.

Test Plugs
