What is a key factor to check for adjacent to a structure during triage?

A critical factor to check for adjacent to a structure during triage is the presence of power lines. This is important because downed or damaged power lines can pose significant hazards to both responders and residents during wildfires or other emergencies. In a triage situation, identifying power lines allows for assessing risks associated with electrical hazards, which can lead to electrocution or fires if the lines are not properly secured. Understanding the location and condition of power lines helps responders make informed decisions regarding safety protocols and evacuation strategies for affected areas.

Other factors like access roads, emergency services, and natural barriers are also relevant during triage, but they serve different purposes. Access roads facilitate entry for emergency vehicles, while emergency services availability can impact response effectiveness. Natural barriers can provide protective features against fire spread but do not present the immediate danger that downed power lines do. Thus, the focus on power lines highlights an urgent safety concern that is paramount in triage assessments.
