The incident type that is limited to one operational period is Type 5 in the Incident Command System (ICS).

Direct answer

In ICS, a Type 5 incident is the least complex and is typically handled within a single operational period (no shift changes or extended operations). It usually does not require a written Incident Action Plan (IAP) and is managed with just a few single resources, with Command and General Staff only involved if really needed.

Quick context for exam-style question

If you see a multiple-choice question like:

“Which incident type is limited to one operational period, does not require a written Incident Action Plan, involves Command and General Staff only if needed, and requires several single resources?”

the correct choice is Type 5 incident.

Other types generally involve:

  • Type 4: May last into a second operational period and is slightly more complex.
  • Types 3–1: Involve multiple operational periods, more resources, and written IAPs.

TL;DR: For “which incident type is limited to one operational period,” the answer is Type 5.
