Operational control is a Safety Management System component that borders much on implementation
of safety strategies and tactics. This study focused on three key operational control elements viz: Scheduled inhouse inspections; Proper display of safety/ caution signs; and Resident Safety Officer at sites and the results show t-values of -7.790, -8.667 and -11.040 respectively. Whereas a regular monitoring and accountability are necessary to ensure effective operational control (Barrick Gold Corporation, 2010), a typical Nigerian construction company measures below the critical t-value of 1.99 on Scheduled in-house inspections; Proper display of safety/ caution signs; and Resident Safety Officer at sites. During site walk-around of this study, it
was observed that supervisors and project managers moved round the site to monitor work progress but it was obvious that they hardly had an eye on safety.
