A safety manager at a factory wants to measure the usage rate of protective gear that employees wear during daily tasks to identify areas for improvement. Which data collection method is best for gathering actual day-to-day usage while workers assemble parts?
Watching how employees manage gear while they operate equipment
Reviewing employee safety incident reports
Requesting feedback from employees through a written questionnaire
Looking up worker safety statistics from an external database
Watching how employees manage gear while they operate equipment is a form of direct observation that captures data in real time. This method reduces the possibility of inaccuracies associated with self-reporting from surveys or reliance on external data sources. Surveys can overlook subtle factors that employees do not report, and external databases contain generic data not specific to the factory. Reviewing incident reports only provides data on safety failures, not on routine, daily usage.
