True or False: Portable lighting is not required at every fire scene.

The statement that portable lighting is not required at every fire scene is considered true. Portable lighting is not a mandatory requirement at all fire scenes; however, its use is often determined by various factors, including the size of the scene, the time of day, and the specific needs of the investigation.

In adverse conditions, such as during nighttime or in enclosed spaces where natural light is limited, portable lighting can be crucial for ensuring safety and facilitating comprehensive visual assessments. However, in scenarios where visibility is adequate, and the area is safe to navigate without additional lighting, it may not be deemed necessary.

While the other options suggest conditions under which portable lighting might be required, they do not change the fact that it is not an absolute necessity at every scene. Therefore, determining the need for portable lighting is based on the specifics of the situation rather than a blanket requirement.
