Question: In a situation where equipment cannot be fully locked out due to continuous operation required by production, what alternative control measures are acceptable, and under what conditions?

Answer options: ✅ Only energy isolating devices or alternative methods that provide effective protection and are part of an approved written procedure are acceptable, with strict adherence to safety protocol.

• No work is permitted if the equipment cannot be fully locked out.
• Verbal instructions from a supervisor are sufficient substitute for LOTO.
• Using warning signs as the sole safety measure.

Correct answer: Only energy isolating devices or alternative methods that provide effective protection and are part of an approved written procedure are acceptable, with strict adherence to safety protocol.

Explanation: If full lockout is not feasible while maintaining continuous operation, alternative protective measures, such as interlocks, specialized safeguarding, or remote operation, must be implemented through a documented and rigorously followed alternative control procedure to maintain equivalent safety as stipulated by CSA Z460-18.
