Which document is used to record a PSO's time of arrival and departure?

The correct selection, which is the DHS form 139, serves as a time and attendance record specifically designed for Protective Security Officers (PSOs). This form is utilized to accurately document the arrival and departure times of PSOs during their assignments. Recording these times is essential for maintaining accountability, ensuring proper staffing, and tracking work hours for payroll and operational efficiency.

In the context of the other forms mentioned, they serve different purposes. For instance, DHS form 1103 is associated with vehicle inspections and authorization, while DHS form 3155 is typically related to incident reporting or situational assessments. The DHS form 3155 continuation is an extension of the aforementioned reporting document but does not pertain to time tracking. Understanding the specific purpose of each form helps ensure that PSOs effectively manage their documentation responsibilities while on duty.
