Emergency situations may occur at any time during the day or year. It is beneficial to conduct drills in ways that reflect this variability. Make the drills realistic, but do so safely. For example, vary the times and conditions for drills, to include:

• Class or service changes.
• Recess, gym classes, social hours, events, and meetings.
• Arrival and dismissal times.
• Times when food service areas are occupied.
• After hours (i.e., dances, theater, athletic events, community functions).
