When searching for victims, which two factors should be felt for?

When searching for victims, particularly in rescue scenarios, the factors that should be actively felt for include contour and weight. Contour refers to the outline or shape of potential victims, which can help rescuers determine if there are individuals trapped or entangled in debris. Identifying contour is essential because it allows rescuers to recognize areas where someone might be located without visibility.

Weight is also a critical factor, as even slight movements or shifts in weight can indicate the presence of a victim. When searching through rubble or in confined spaces, detecting weight can assist rescuers in locating individuals who may not be visibly discernable due to obstacles or darkness.

In contrast, the other choices—temperature and noise, visibility and odor, movement and breathing—are less practical or reliable for locating victims during searches. Temperature may help in assessing conditions but does not directly indicate the presence of a victim, and noise can be misleading in chaotic environments. Additionally, visibility and odor, while useful in certain contexts, may not directly aid in tactile searching, and movement and breathing are often difficult to detect unless rescuers are very close to the victim.
