Under what condition can the number of required watchpersons at a construction site be reduced?

The requirement for watchpersons at a construction site is primarily rooted in ensuring safety and security, especially in the absence of direct supervision. When an alarm or video monitoring system is implemented, it serves as a technological substitute for the physical presence of watchpersons. These systems can provide constant monitoring, alerting appropriate personnel in case of emergencies or unauthorized access.

The presence of an alarm system or video surveillance can deter potential intruders or identify incidents as they occur. This technology can effectively reduce the need for multiple watchpersons, as these systems can often handle security functions that would traditionally require human oversight. Consequently, sites with such technological measures can demonstrate that they maintain an adequate level of security, thus allowing for a potential reduction in the number of watchpersons required.
