Energy Control Review
An Energy Control Review is a formal, documented audit and validation of a facility's hazardous energy control program, including lockout procedures, devices, training, and field practice. It verifies effectiveness, compliance with standards like CSA Z460 and OSHA 1910.147, and adherence by authorized workers. This structured process ensures energy sources are isolated and controlled before maintenance, aligning with WorkSafeBC OHSR Part 10 requirements.
On a manufacturing shop floor in BC, an Energy Control Review is implemented as a recurring inspection program covering all machines with hazardous energy (electrical, mechanical, hydraulic, etc.). It involves observing real tasks requiring lockout or approved alternatives like control system isolating devices (CSIDs). The review verifies steps: preparation for shutdown, isolation, lockout application, zero-energy state verification, safe work performance, and release from lockout. Documentation includes machine identification, date, employees, inspector, deviations, and corrective actions. It integrates with WorkSafeBC approvals for CSIDs, ensuring procedures remain aligned with approval letters and design changes are evaluated.
- Energy Control Reviews not performed at required frequency or scope, such as semi-annual audits per CSA Z460, leading to degraded lockout practices and difficulty demonstrating due diligence.
- Audits focus only on paperwork, ignoring field practice and worker understanding, missing direct observation of lockout activities and interviews about responsibilities, as required by CSA Z460.
- Uncontrolled changes to equipment or procedures invalidate WorkSafeBC approvals or risk basis, such as modifications to control systems without updating procedures or checking impact on performance levels, risking non-compliance.
How often must an Energy Control Review be performed in a BC manufacturing facility following CSA Z460:20?
Under CSA Z460:20, the facility must develop and document a formal compliance audit of lockout and other energy control procedures at least semi-annually, and an authorized management employee must perform annual audits. The volume of audits must adequately represent the size of the plant and the number of authorized employees.
What minimum information must be recorded in an Energy Control Review to be CSA-compliant?
CSA Z460 requires documentation including: identification of the machine, equipment, or process; date of inspection; employees included; person performing inspection; evidence that the audit is designed to correct deviations (e.g., findings and corrective actions); and, where lockout is used, a review between inspector and each authorized employee of their responsibilities.
During an Energy Control Review, how is 'verification of effective lockout' assessed against WorkSafeBC Part 10?
WorkSafeBC OHSR requires that before work, a worker must verify all energy sources are effectively locked out. The auditor must confirm workers identify all energy sources (not just electrical), apply lockout to all required isolating devices, and use a test or try procedure (e.g., attempt start, check zero pressure) to confirm isolation before starting work.
