Which Incident Type necessitates utilizing one or two single resources with up to six personnel?

The correct answer is Type 5. Type 5 incidents are characterized by their minimal complexity and resource needs. In this type, response efforts typically involve one or two single resources, which can include units such as an engine company or a small crew, to manage the situation effectively. The personnel involved in a Type 5 incident generally do not exceed six individuals.

This classification is essential in the National Incident Management System (NIMS) framework, as it allows for a clear understanding of the resources and organizational structures required to manage various incidents. Type 5 incidents are often local emergencies or incidents that can be controlled with basic resources and a small team. Understanding this helps responders to allocate resources appropriately and to ensure that response efforts are commensurate with the incident's complexity and needs.

In contrast, the other types—Type 4, Type 2, and Type 3—represent increasingly more complex scenarios with greater resource demands and personnel involvement, making them unsuitable for the characteristics described in the question.
