Preventive Maintenance Questions

Overview

BC Crane Safety is providing these self-planned inspection questions to educate crane stakeholders for a better understanding of their health and safety responsibilities to comply with WorkSafeBC’s Occupational Health and Safety Regulation and relevant CSA standards.

This set of questions has been developed in conjunction with WorkSafeBC's Crane/Mobile Equipment Team. It is recommended that crane employers and owners refer to these questions to improve their company or site safety management systems.

Act - Post-Inspection Discussion

Continuous Improvement Next Steps

During the post-inspection discussion, please encourage the worksite representatives to act on the key learnings or areas of improvement.

If unsure, help them to identify 1-2 measures that need to/must be corrected, changed, eliminated or modified to improve worker and worksite safety.

The Act stage of the Plan-Do-Check-Act process is where the worksite representative/superintendent implements an improved baseline of operations and remeasures implementation to ensure improvements/corrections. By measuring implementation i.e., identifying a lower level of risk, reducing hazard severity/frequency, the worksite is taking positive action towards improved health and safety.
