Fire Protection Reg. 854 (Mines and Mining Plants.) Regulation 854 sets out specific requirements to ensure that the health, safety, and welfare of workers and the general public, as well as property, are not adversely affected by the possibility of a fire on surface or in the underground workings. Part II Requirements Fire Protection: In this case of a fire, employers are required to develop procedures for the protection of workers in underground and surface mines, or mine plants. 7 Fire Protection Reg. 854 (Mines and Mining Plants.) Cont. A suitable number of workers must be trained in the fire fighting procedures and their names shall be posted. Workers must be tested annually. The owner of a mine shall make available, at the owner s expense, an adequate number of workers trained in mine rescue work. Training facilities, materials and equipment to be stored are the responsibility of the owner. A mine rescue operation shall be under the direction of a supervisor in charge of the mine. Notice must be given to an inspector and the mine rescue officer when the services of a mine rescue crew are required. 8 4
Fire Protection Reg. 854 (Mines and Mining Plants.) Cont. An effective alarm system must be in place to warn workers in the underground environment and it must be tested annually for each work shift. A report of each fire alarm test of procedures must be kept on file for a period of three years. Where procedures include the use of safety stations for the protection of workers during a fire they must be: sized to accommodate workers, sealable to prevent gases from entering, have air and water supplied, and allow for communication to surface. 9 Fire Protection Reg. 854 (Mines and Mining Plants.) Cont. Fire extinguishing equipment must be provided at fire hazard areas, electrical installations (substations, transformers power racks etc.) and shaft levels. Fire suppression systems are typically dry chemical initiation systems required on all equipment that is underground and contains more than 100 litres of flammable hydraulic oil. All motor vehicles must be equipped with a hand held fire extinguisher. 10 5
Fire Protection Reg. 854 (Mines and Mining Plants.) Cont. Motor vehicles must be maintained in accordance with procedures developed by the employer for testing, maintaining and inspecting vehicles to ensure they are in safe working condition. Routine schedules for motor vehicle maintenance must take into account manufacturers recommendations for maintenance and use. Gasoline, propane or other volatile fuel can not be used in internal combustion engines underground. 11 Fire Protection Reg. 854 (Mines and Mining Plants.) Cont. Hot work underground including welding, cutting or the use of a burning torch, requires written procedures for safe use. Only workers that are competent or under the direction of a competent worker shall use hot work equipment. Suitable fire extinguishing equipment must be available. Examination of the hot work area must be completed when work has stopped and rechecked within 2 hours. Workers must be protected from fumes through the use of ventilation or by wearing personal protective equipment (respirators). 12 6
13 Summary of Fire Protection Protection Requirements for Workers Structures and Equipment Procedures are required for both surface and underground operations to respond to fires and other emergencies. Workers require training and equipment must be available to provide an adequate response. Equipment underground must be maintained, be safe for operation, protected in the advent of fire, taking into consideration manufacturers recommendations. Garages, storage areas and other key locations require fire suppression systems and fire doors that are maintained and checked in accordance with the regulatory requirements. Part IV Hoist Plants Reg. 854 (Mines and Mining Plants.) 14 7
Hoist Plants Reg. 854 (Mines and Mining Plants.) Multi-deck stages used for shaft sinking must be designed by an engineer and built in accordance with the design. No mine hoisting plant shall be operated without a written statement by a professional engineer identifying the location of the Hoist Plant and the maximum load that can be carried, including material or persons. A competent person shall be appointed to examine the mechanical parts of a mine hoisting plant at routine intervals for testing and maintenance. 15 Hoist Plants Reg. 854 (Mines and Mining Plants.) During the development of a mine shaft a conveyance used to transport workers is required when the vertical depth below surface exceeds 50 meters. 16 8
Hoist Plants Reg. 854 (Mines and Mining Plants.) Hoists used to transport workers must kept in safe working condition. Competent person(s) shall examine the mechanical workings of the hoist plant in accordance with the regulation daily prior to first being used.

A shaft wire rope shall not be used unless a 2.5 meter sample of the rope has been subject to a destructive test in accordance with the CSA Standard G-4 Steel Wire Rope for General Purpose and for Mine Hoisting and Mine Haulage. 18 9
Hoist Plants Reg. 854 (Mines and Mining Plants.) The Materials Testing Lab (MTL) located in Sudbury is approved by the Minister of Labour to test wire ropes. The MTL issues Test Certificates as a record of the breaking strength of a sample of wire rope used for transporting people and material. Wires ropes are subject to routine tests as set out in the regulation until they are removed from service. A competent person using a electromagnetic testing device shall test all hoist ropes at prescribed intervals. Ropes must be removed from service if found to be defective or if the breaking strength falls below 90% of its original breaking strength. 19 Summary Hoist Plant Requirements Hoist plants and shaft sinking equipment Designed and built according to good engineering practice.
