In the CHECK phase, which activity is included?

• A. Accident investigation
• B. Measuring performance
• C. Planning
• D. Implementing

Answer: (B)

The CHECK phase focuses on verifying how well things are actually working by measuring performance. It’s about collecting data, monitoring indicators, and comparing actual results with what was planned to see if safety objectives are being met and whether controls are effective. This is where you assess progress, audit procedures, and look for gaps or deviations so you know what needs adjusting.

For example, you would track outcomes like evacuation drill times, training completion rates, or audit findings to gauge safety performance. Accident investigation, planning, and implementing align with other phases: planning is the initial design of controls, implementing is putting those controls into action, and accident investigation is typically part of learning from incidents and feeding into improvements—often during the Act phase.
