Control of Hazardous Energy - Lockout and Other Methods

Scope of Work

1. Consider expanding Standard scope to include energy derived from radioactive isotopes (i.e., nuclear energy).
    
2. Review and update reference documents.
    
3. Review definitions and terminology.
    
4. Proposal (based on Z244.1) that maintenance activities not be considered separately from routine and repetitive tasks.
    
5. Simplify the explanation and process to use when conducting Risk Assessments associated with Lockouts. Consider risk of remote start-ups (remotely-control systems).
    
6. Review need for approval from RAHJ for complex group lockout.
    
7. Criteria for selection of and examples of other control methods.
   1. Proper positioning of Approved Safe Work Procedures under Other Methods. Current wording does not accurately position all of the needs for ASWPs in the work place.
   2. Sanction the use of “Approved Isolation Procedures”, where the devices used for your protection are under your direct control therefore there is no chance of “Inadvertent Re-energization”.
   3. Quantify the difference between “Inadvertent Re-energization” vs “Inadvertent Contact” (includes unintentional energization of a system thought to be isolated or controlled).
8. Expand on the requirements and examples provided in the Annex for what a sound Lockout Program would involve in a more complex Industrial/Construction settings where the use of Complex Group Lockout is not attainable.
9. Review of specifications for verifying secure isolation, absence of stored energy, verification of true lockout (especially on complex, remotely controlled equipment).
10. Connect Z460 with the new Z767 Standard on Process Safety Management by providing guidance on applying Z460 to chemical processes (CSA Z767) – primary (energy release) and secondary (evolution of hazardous materials) hazards.
11. Add references to new CSA Z463 (Electrical Maintenance) and Z1010 (Work in Extreme Conditions) standards.
12. Expand on the requirements and examples provided in the Annex for Device/Equipment Nomenclature, expounding on its importance in ensuring the Correct Equipment and associated Isolating Devices have been utilized for isolation (labelling and identification).
13. Expand/Promote the use of supporting software the creation of Master Equipment Listings (MEL) using the agreed to Nomenclature from which the software then creates Equipment Labeling, and then subsequently creates all of the Lockout Isolation Forms and Lockout Tags so that the subsequent forms and tags all utilize the same nomenclature as will then be found on the field devices to ensure Correct Component Verification. (Annex material)
14. Expand on the requirements and examples provided in the Annex for system drawings, flowsheets, electrical schematics, single-line process flow drawings for use in the design of accurate isolation when working in more complex industrial settings (power plants, refineries, hospitals, etc.).
15. Expand on the requirements (body criteria) and examples provided in the Annex for Mobile Equipment (including high-voltage batteries).
16. Consider adding a specific section in the Standard dealing with unique needs of construction sites, providing guidance on things like Meggering, Shooting LOOPs, doing Point to Points, Isolating Generators, Man Lifts, and UPUPs.

17.  Develop a new Annex for work on Alternative Energy Generation equipment (solar, wind, etc.)
