What is one key responsibility of the watchperson at construction sites?

One key responsibility of the watchperson at construction sites is to secure all entries and exits. This duty is vital for maintaining the safety and security of the construction site. By monitoring and controlling access points, the watchperson helps to prevent unauthorized individuals from entering the site, thus protecting the equipment, materials, and personnel involved in the construction project. This is particularly important in ensuring that only trained and authorized personnel are present, which reduces the risk of accidents or potential theft.

In contrast, although overseeing vault construction, monitoring employee work shifts, and managing materials storage are important tasks within the construction environment, they do not specifically fall under the primary responsibilities of a watchperson. The watchperson's role is focused more on security and safety measures rather than the operational or logistical aspects of construction management.
