during work or during a work break, Job Safety Analysis JSA Job safety analysis is a procedure which helps. integrate accepted safety and health principles and practices into a particular. task or job In a JSA for each basic step of the job it is to identify potential. hazards and to recommend the safest way to do the job. Hazard Source or situation with potential for harm something that can. cause body injury occupational illness damage company property. Hazard Identification Risk Assessment HIRA Hazard Identification. Risk Assessment is to identify and evaluate the hazards Risk and put. controls measures for safe execution of activities. Inspection Checking the work permit controls in practice using a prepared. Lockout Placement of a lockout device on an energy isolating device in. accordance with an established procedure ensuring that the energy isolating. device and the equipment or material being controlled cannot be operated or. moved until the lockout device is removed, Lockout device A device that utilizes a positive means such as a lock. either key or combination type to hold an Electrical energy isolating device. in a safe position and prevent the energizing of a machine or equipment. Tag out Placement of a tag out device Danger Tag on an energy isolating. device in accordance with the applicable sections of this procedure to. indicate that the energy isolating device and the equipment being controlled. may not be operated until the tag out device is removed Tag out devices. are placed in the same location as lockout devices. Tag out device A prominent Danger Tag such as a tag and a means of. attachment which can be securely fastened to an energy isolating device or. source of systems containing hazardous materials in accordance with an.

6 STEPS OF PROCEDURE,6 1 SAFETY PRECAUTIONS DURING OPERATION WORK IN A. CONVEYOR BELT,6 1 1 Belt sway Belt Tracking, 1 Do not wear loose clothing or jewelry near the conveyor belt. 2 Do not put your hands on a moving conveyor belt,3 Provide proper illumination at the working zone. 4 Insure the OK condition of pull cord and emergency stop switch. of the conveyor belt, 5 Keep one skilled person with walky talky near the pull cord. 6 Communicate with control room before aligning tracking the. running belt, 7 Move the trainer idler by pushing pulling its frame from the ends.
8 Do not try to move any damaged jammed trainer idler. 6 1 2 Spillage recovery cleaning, 1 Do not wear loose clothing or jewelry near the conveyor belt. 2 Do not put your hands on a moving conveyor belt,3 Do not stand walk on the belt. 4 The spillage material accumulated below the return side belt or. on the deck plate should be cleaned by hand scrappers only. 5 The spillage material should be collected in bucket and it should. not throw down from conveyor gallery, 6 Throw the collected spillage material on belt only from those. positions where the safety guards are provided on belts as per. safety standard SS ENG 18, 7 Never heap up the spillage material at the tail end of the. 8 If the spillage material is in large amount more than one ton. the conveyor, 9 Should be taken in local operation mode Start the belt in.
empty condition Keep one person at pull cord Communicate with. control room and start throwing the collected spillage material by. bucket on the running belt from the safety guard positions only or. station made for this purpose,Note Uncontrolled once printed Page 7 of 53. Document Name, The Tata Power Company Ltd Conveyor Belt Safety Procedure. Document Ref No Date of Issue,TPSMS GSP CONV 002 REV 01 30 06 2016. 6 1 3 Start Stop of belt, 1 If a conveyor belt needs stopping it should never be stopped in. load condition except emergency, 2 If the high speed coupling in the drive is a fluid coupling the.
number of start stop of the conveyor belt should not be more than. 4Nos Hr at the same time there should be a minimum gap of 15 to. 20 minutes between two consecutive start stop, 6 2 SAFETY PRECAUTIONS DURING MAINTENANCE WORK IN A. CONVEYOR BELT,6 2 1 Conveyor drive, 1 Stop the conveyor belt when it is empty Never stop. the belt in load, 2 Do the positive isolation of all the electrical power. sources of conveyor system, 3 Before changing replacing of any component of the. drive coupling gearbox or motor do the positive, isolation of potential energy source take up unit of.
the belt by holding it with a pair of suitable chain. blocks Select the chain blocks from table1 To hold. take up lift it by 6 8 inches to take GTU load by chain. blocks It is also desirable although not a must to. place the I beam channel at correct position under the. gravity take up Internal inspection of gearbox,components should be done through the provided. inspection cover only and its top cover should not be. opened at site,Note Uncontrolled once printed Page 8 of 53. Document Name, The Tata Power Company Ltd Conveyor Belt Safety Procedure. Document Ref No Date of Issue,TPSMS GSP CONV 002 REV 01 30 06 2016. 4 Whenever the gearbox or and motor is required to. change the factor of safety for the gearbox should not. be less than 2 0 Attention should be given at,design selection phase.
5 The oil level in fluid coupling should be maintained. as per mentioned quantity in its manual The slip in. fluid coupling should be less than 3,6 In the pin bush and gear couplings the minimum. gap between the flanges should be maintained as per. the recommended value according to their size, All the moving rotating components of the drive should be. covered by standard safety guards,6 2 2 Counter Weight. 1 Stop the conveyor belt when it is empty Never stop the. belt in load, 2 Do the positive isolation of all the electrical power sources. of conveyor system, 3 Spillage material accumulated on counter weight should be.
removed on regular interval, 4 A counterweight and its pulleys suspended above the floor. or ground in an area where an employee could walk shall. have an enclosure around the area of impact or a catch pan. under the counterweight of such strength and design to hold. the counterweight and pulley from dropping to the ground. floor or platform, 5 The concrete slab type counter weight should be replaced. by box type closed counter weight, 6 The rope of the counter weight should be checked on. regular interval for its strands condition and bulldog grip. When two wire ropes hang the counter weight the wire ropes. should be of opposite hands This will avoid twisting of counter. weight about its vertical axis,6 2 3 Chute Receiving or discharge chutes. 1 Stop the conveyor belt when it is empty Never stop the belt.

non impact wall The inspection window can be used for. dislodging the jammed material on impact walls or inspection of. inside condition of chute, 8 To protect the mother plate of a chute the hard faced liner or. wear resistant liner plate should be fixed at the impact zone of. chute walls, 9 Before executing the welding or gas cutting job in chute the. belt below the chute must be covered by a fire resistant cloth. 10 There must be proper clearance between the pulley. discharge pulley or tail pulley end face and the inside wall of. If the dust content in the material handled is high a dry fog or. vacuum cleaning system should be installed at the receiving. 6 2 4 Belt joint Vulcanized or mechanical, 1 Stop the conveyor belt when it is empty Never stop the belt in. 2 Do the positive isolation of all the electrical power sources of. conveyor system, 3 Fix the jam angle with deck plate stringer at a sufficient free. length 3 m to 5 m from the joint towards head end of the. conveyor belt, 4 To pull the loose belt it should be clamped with a pair of.
angles also called as pulling angles at a distance of 3 to 5 m.
