Which elements are identified during initial size-up after arriving on scene?

• A. Identify life hazards and locate the fire only
• B. Determine access and egress solely
• C. Identify life hazards, locate the fire, determine access/egress, and anticipate hazards and tactical needs
• D. Establish water supply and interior attack strategy

Answer: (C)

The main concept tested is that initial size-up on arrival is a quick, multidimensional assessment that shapes your immediate actions. You must identify life hazards, locate where the fire is and how it’s likely to spread, determine how you and others will enter and exit the structure, and anticipate hazards and tactical needs that could affect safety and resources. Life hazards focus on occupants who may need rescue and on the safety of crews, as well as potential structural or utility-related dangers. Locating the fire gives you a sense of its size, location, and likely paths it may take, which informs search priorities and exposure considerations. Determining access and egress identifies the best entry points, travel routes, and escape paths, which is essential for safe and efficient progression. Anticipating hazards and tactical needs means picturing what could go wrong (collapse, flashover, backdraft, hidden fires, utilities) and what actions the incident will require (ventilation, forcible entry, search, rescue, additional resources, water supply planning). Together these elements provide a complete, actionable picture for the initial response. Focusing only on life hazards and locating the fire misses key aspects of how you’ll operate safely, focusing solely on access/egress ignores hazards and the fire’s behavior, and concentrating on water supply or interior attack strategy after arrival bypasses the broader assessment that guides those tactical choices.
