What is the time frame for completing DHS Form 3155?

The requirement for completing DHS Form 3155 stipulates that it must be completed and submitted within 24 hours of the incident or occurrence it pertains to. This is critical for ensuring timely communication and coordination among various security entities involved in managing incidents. This time frame allows the necessary authorities to initiate appropriate responses and maintain situational awareness effectively.

While some options mention shorter time frames or suggest that not all PSOs need to complete the form, these do not align with the established guidelines for reporting incidents. The 24-hour window facilitates thoroughness in reporting while still emphasizing the urgency required in incident management protocols.
