57 www.esdnl.ca Worker Killed By Mixing Machine NARRATIVE: An employee was assigned the task of cleaning the inside of a sand mixer. The task was conducted during a break in the production cycle, caused by routine maintenance work. He did this without anyone else’s knowledge. While he was engaged in this, out of sight and hearing of the others, an electrician started the machine, killing the man inside. This plant had a written lockout procedure, training had been given, and all affected employees (including the deceased), were issued keys and locks.

58 www.esdnl.ca  What caused the death of the worker?  Do you believe there are multiple causes?  Are multiple OSHA Standard violations involved?  What could upper management have done?  What could the supervisor have done?  What could the co-workers have done?  To what extent was attitude responsible?  To what extent is a lack of written policy responsible?  To what extent is a lack of training responsible?  Do you believe there is a single cause to this accident that, if removed would have prevented it?

59 www.esdnl.ca Worker Killed By High Voltage NARRATIVE: A 13,800-volt main circuit breaker was under routine inspection. A test instrument was used to check for electrical energy. No electrical energy was detected at the primary power contacts in the circuit breaker. To verify the operation of the tester, the sensitivity was readjusted and checked against a known 120-volt receptacle. The tester was found to be operable. As the journeyman electrician approached one of the contacts with a shop towel, an explosion, engulfed him in flames. The power from the public utility company to the main circuit breaker had not been shut off.

60 www.esdnl.ca  What caused the death of the worker?  Do you believe there are multiple causes?  Are multiple OSHA Standard violations involved?  What could upper management have done?  What could the supervisor have done?  What could the co-workers have done?  To what extent was attitude responsible?  To what extent is a lack of written policy responsible?  To what extent is a lack of training responsible?  Do you believe there is a single cause to this accident that, if removed would have prevented it?

61 www.esdnl.ca 1. ENERGY CONTROL PROCEDURES 2. EMPLOYEE TRAINING 3. PERIODIC INSPECTIONS  THREE ELEMENTS TO THE PROGRAM:

62 www.esdnl.ca

63 What a typical Lock-Out / Tag-Out looks like with an equipment lock.

64 www.esdnl.ca What a typical Lock-Out / Tag-Out looks like with a personal protection lock.

65 www.esdnl.ca What a Lock-Out / Tag-Out looks like with a contractor & personal protection lock.

66 www.esdnl.ca Occasionally you may see a yellow tag without a lock on equipment that is out of service.  This machine is Tagged Out because it will not run vThe tag will tell you what is wrong with the equipment  Never attempt to operate equipment that has been tagged

67 www.esdnl.ca In order to properly block or secure any piece of mobile equipment, you must block or pin all articulation joints. Failure to properly secure articulation could result in vehicle movement when it is blocked in the raised position.

68 www.esdnl.ca Adequate Blocking?

69 www.esdnl.ca everyone working on equipment must place their own locks and tags Equipment already has a lock and tag on it. Equipment already has a lock and tag on it. Do I have to place my own locks & tags? YES!

70 www.esdnl.ca The following examples illustrate tampered lockout hasps. These hasps are easily pried open with minimal effort. The construction and design does not provide adequate protection based on policies we have set or industry standards.

71 www.esdnl.ca

72 The heavy-duty hinge-style hasp offers added pry resistance. Steel construction with 9/32" diameter shackles. This new hasp will restore lockout security. This picture illustrates the new lockout hasp. 4 lock (stock code 2060184) 8 lock (stock code 2060192)

73 www.esdnl.ca Properly plan the job. Notify all affected employees in the area of work. Shut down the equipment at the operating controls. Isolate all energy sources to equipment. Lock and tag all isolating devices Dissipate all stored or residual energy sources. Verify the isolation.

74 www.esdnl.ca Stay clear of the area as much as possible. Never attempt to assist. Never interfere or tamper with a lock or tag. Report all unusual situation to your supervisor or foreman.

75 www.esdnl.ca

76 Loose parts Deformed or missing pins Damage to outer jacket or insulation Evidence of possible internal damage Portable cord and plug connected equipment and flexible cord sets (extension cords) shall be visually inspected before use on any shift for external defects:

77 www.esdnl.ca Portable equipment must be handled in a manner which will not cause damage. Flexible electric cords connected to equipment may not be used for raising or lowering the equipment. Flexible cords may not be fastened with staples or otherwise hung in such a fashion as could damage the outer jacket or insulation. Flexible cords may not be fastened with staples or otherwise hung in such a fashion as could damage the outer jacket or insulation.

78 www.esdnl.ca A GFCI is device intended for the protection of persons that functions to de-energize a circuit.

79 www.esdnl.ca GFCIs constantly monitor electricity flowing in a circuit. If the electricity flowing into the circuit differs by even a slight amount from that returning, the GFCI will quickly shut off the current flowing through that circuit. GFCIs work quickly, so they can help protect persons from severe electric shocks and electrocution. GFCI do not require a ground.
