Final answer:
It is False that security guards should leave empty spaces in their duty notebooks for later additions. Records should be kept in a continuous manner, and any additional information should be added in the next available space with appropriate cross-referencing.
Step-by-step explanation:
The statement is False. In the context of security work, a duty notebook is an important document used to record all relevant activities, incidents, and observations made during a shift. Leaving empty spaces could lead to alterations or additions that may call into question the integrity and chronological accuracy of the records. Instead, security guards should write entries in a continuous manner, without leaving gaps, and any mistakes should be crossed out with a single line, initialed, and the correct information written nearby. If additional information needs to be added later, it should be done in the next available space with a reference to the relevant entry so the records stay chronologically intact.
