  8. ON OFF SYSTEM CONTROL SWITCH CIRCUMSTANCES OF INJURY REASONS FOR EQUIPMENT NOT BEING TURNED OFF • Afraid of Slow Down in Production. • Afraid It Would Take Too Long. • Not Required by Company Procedure. • Worker Didn't Know Power Was on. • Worker Didn't Know How to Turn Off. • Did Not Think It Was Necessary. • Task Could Not Be Done With Power Off.

  9. ON OFF SYSTEM CONTROL SWITCH CIRCUMSTANCES OF INJURY REASONS FOR EQUIPMENT BEING TURNED ON • Accidentally Turned on by Injured Employee • Co-Worker Accidentally Turned Equipment On • Equipment Moved When Jam-up Cleared • Equipment Unexpectedly "Cycled" • Parts Still in Motion (Coasting)

  10. CASE STUDY #1 KILLED BY THE MOVING PARTS OF A SAW Narrative: An Employee Was Cleaning the Unguarded Side of an Operating Granite Saw.

Adequate Notice to the Employee Who Applied The Device, of the Removal of the Device BeforeThat Employee Returns to Work.

  42. OUTSIDE CONTRACTORS MUST: • Inform Representatives of the Facility Of Their LO/TO Procedures and Devices. • COMPANY REPRESENTATIVES MUST: • Inform the Contractor of Internal LO/TO Procedures and Devices. • Ensure That the Contractor(S) Are Following LOTO Procedures. CONTRACTOR SAFETY REQUIREMENTS

  43. TIPS FOR USING CONTRACTORS • Remember, You Control Your Facility! • Review Their Procedures With Them Before Starting the Job! • Determine Their Safety Performance Record! • Determine Who Is in Charge of Their People! • Determine How They Will Affect Your Employees! • Ensure Your Data on Your Facility Is Accurate!

  44. KEY ELEMENTS TO AN EFFECTIVE PROGRAM 1. Develop and Strictly Adhere to LO/TO Procedures. 2. Establish and Enforce Safe Work Practices. 3. Ensure Proper Training and Supervision. 4. Strengthen and Modify Present Policies. 5. Understand the Relationship Between 29 CFR 1910.147 And the Business or Industry Involved.

  45. EQUIPMENT REQUIREMENTS DEVICES AND TAGS MUST BE: 1. Durable 2. Standardized 3. Identifiable 4. Substantial DEVICES AND TAGS ARE: 1. Designed to Prevent Accidental Energization. 2. Not Designed As a Substitution for Security.

  46. CASE STUDY #1 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.

  47. DANGER LOCKED OUT DO NOT OPERATE This Lock/Tag may only be removed by NAME: _______________ DEPT : _______________ EXPECTED COMPLETION DATE: ________________ TIME: _________________ QUESTIONS TO BE CONSIDERED • 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?

  48. CASE STUDY #2 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.

  49. DANGER LOCKED OUT DO NOT OPERATE This Lock/Tag may only be removed by NAME: _______________ DEPT : _______________ EXPECTED COMPLETION DATE: ________________ TIME: _________________ QUESTIONS TO BE CONSIDERED • 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?

  50. CASE STUDY #3 WORKER KILLED BY STORAGE MECHANISM NARRATIVE: A stock handler entered a computer controlled storage and retrieval area apparently to perform stock inventory. While performing this work he was crushed between the robot retrieval vehicle and a third level post, when the vehicle responded to an electronic command. It was found that even though there were a number of disconnect switches on the vehicle and main console none had been used. The plant had no written lockout procedure and workers had not been trained or advised regarding entry into this area.
