5. 4 Determine the limits of the machine Identify the hazards Estimate the Risk Evaluate the Risk Reduce the Risk Risk Assessment /Reduction Risk Controls

6. 5 Control of Hazardous Energy LOCKOUT for all maintenance/repair work activities or ‘operational’ tasks if a worker : 1) removes or bypasses a guard or other safety device 2) requires to place any part of his or her body into an area on a machine or equipment where work is actually performed… Release of Stored Hazardous Energy moving parts – gravitational energy (electrical, mechanical, hydraulic, pneumatic, nuclear, thermal, others..) Alternative Methods to Lockout, operational tasks for minor service…or service and/or maintenance tasks carried out with ‘power on’. …… subject to risk assessment.

7. 6 Lockout Procedure Notification Shutdown Isolate energy sources Relieve/restrain stored energy Lockout energy-isolating devices Verification and clearance of personnel Perform work Inspect/check area Remove locks/re-energize Restart

8. 7 Normal Production Operation Minor tool changes and adjustments, and other minor servicing activities, which take place during normal production operations, are not covered if the are routine, repetitive, and integral to the use of the equipment for production, provided that the work is performed using alternative measures which provide effective protection.

9. 8 Major deficiencies of OSHA 1910.147 Allowing Tags in place of Locks Lack of specific requirements for ‘alternative measures’, operational tasks which are part of normal production and those tasks requiring equipment to be partially energized. Does not address design requirements for effective hazardous energy control for new machines/equipment, other than asking for “capable of being locked out”

10. 9 Major deficiencies of ANSI Z244 Allowing Tags in place of Locks Alternative methods…….. control reliability, harmonization with other ANSI standards and ISO standards.

11. 10 ISO 14118 Safety of Machinery – Prevention of unexpected start-up For new machinery only, operational requirements not included. ISO standards do typically not cover operational, work place dependent requirements. Those requirements are covered by jurisdictional occupational Health and Safety Regulations.

12. 11 Characteristics of operational tasks…routine, repetitive….. Short of duration Relatively minor in nature Occur frequently during the shift, day.. Performed by operators … Do not involve extensive disassembly Represent predetermined cyclical activities Expected to occur regularly Minimally interrupt the production process Exists even when optimal operating levels are achieved Require task specific personnel training

13. 12 Subjects Covered by Z460 Traditional Lock-out including group lock-out for maintenance and/or service of equipment Release of stored energy, a more systematic approach. Alternative methods to lock-out for partially energized equipment and operational tasks part of normal production where lock-out not possible/feasible. (Risk assessment ‘control reliability’; Review of existing “C” Standards that adopt alternative methods to lock-out).

17. 16 Risk Assessment and Hazard Abatement Establishment risk classification based on: -Frequency-Severity RISK related to the considered hazard SEVERITY of the possible harm for the considered hazard is a function of PROBABILITY OF OCCURRENCE of that harm -frequency and duration of exposure -probability of occurrence of hazardous event -possibility to avoid or limit theharm and

18. 17 S -Severity of injury S1-Slight injury - first aid only S2-Serious injury - greater than first aid only E -Exposure frequency E1-Low - less than or equal to once per day E2-Medium - greater than once per day or equal to once per hour E3-High - greater than once per hour P -Possibility of avoiding a hazard P1-Possibility under specific conditions P2-Scarcely possible Risk Assessment and Hazard Abatement Matrix References

19. 18 B 1 2 34 Starting point for risk estimation for the safety related part of the control system. S1 S2 E2 E1 E3 P1 P2 Increasing reliability of components Increasing redundancy and/or monitoring Preferred categories Possible categories which require additional measures Over-dimensioned measures for the relevant risk Risk Assessment and Hazard Matrix

20. 19 INSIGNIFICANT LOW MODERATEHIGH EXTREME RISK Concept of risk reduction using protective measures including safety functions. Risk before pro- tective measures are applied. Tolerable risk Residual risk Increase in risk due to failure of Safety Related Parts SRP of Control Systems control reliability (integrity) MINIMUM RISK REDUCTION FROM ALL PROTECTIVE MEASURES
