Size-Up Matters: Recognizing Hoarding Conditions Before You Commit

Every fireground starts with a size-up. The decisions made in the first few minutes determine everything that follows. We spend countless hours teaching firefighters to identify lightweight construction, recognize collapse indicators, and read smoke. Yet one of the most overlooked hazards on today's fireground is the hoarding environment.

Hoarding conditions are becoming more common across North America, and they present a unique challenge to firefighters. These homes contain significantly higher fuel loads, limited access, compromised structural integrity, hidden fire extension, and restricted escape routes. The problem is that many of these hazards can be recognized before firefighters ever force the front door — if they know what to look for.

The size-up of a hoarding fire starts before the apparatus stops.

Firefighters often focus on smoke conditions during the approach, but the exterior of the building can tell an equally important story.

One of the first clues is excessive storage outside the home. Look for piles of furniture, appliances, boxes, shopping carts, bicycles, scrap metal, or miscellaneous belongings stacked against the structure. Many occupants simply run out of room inside and begin storing possessions outside.

Overgrown vegetation can also indicate neglect. Bushes covering windows, grass several feet high, or trees growing into the structure may suggest the property has received little maintenance.

Pay attention to windows. Are they completely blocked by belongings? Covered with blankets, cardboard, plywood, or aluminum foil? A home with very little visible interior through the windows deserves a closer look.

The driveway can provide additional clues. Multiple disabled vehicles, trailers filled with contents, overflowing trash containers, or piles of discarded items often indicate that storage has become a significant issue.

None of these clues confirms hoarding by themselves, but when several appear together, firefighters should immediately begin adjusting their expectations.

A thorough 360 becomes even more important when hoarding conditions are suspected.

Look for blocked exterior doors, additions built without permits, enclosed porches packed with contents, or storage extending under decks and around exits.

Ask yourself:

• Can occupants actually escape through these doors?
• Can firefighters realistically advance a hoseline through this entrance?
• Are there alternative access points if conditions deteriorate?
• Is fire already involving exterior storage that could compromise egress?

The answers should influence your tactical plan before crews are committed inside.

One of the most valuable tools during size-up isn't a thermal imager or a drone — it's communication.

Neighbors often know more about the home than anyone arriving on the apparatus.

Simple questions may reveal critical information:

• Has anyone been seen coming out today?
• Does the homeowner have difficulty walking?
• Is the house filled with belongings?
• Are doors normally blocked?
• Where does the occupant usually sleep?
• Are there pets or additional occupants inside?

Law enforcement, EMS, utility workers, postal carriers, and code enforcement officers may also have previous knowledge of the property.

A thirty-second conversation can dramatically improve situational awareness.

Once the front door is opened, confirmation usually comes quickly.

Instead of open floor space, firefighters may encounter narrow pathways winding through floor-to-ceiling piles of belongings. Ceilings may disappear behind stacked contents. Furniture may be buried. Rooms may no longer resemble their intended purpose.

Travel becomes slow and exhausting. Advancing a charged hoseline requires significantly more effort. Visibility is reduced further because firefighters cannot sweep large areas with a flashlight or thermal imager.

Even locating victims becomes far more complicated.

One of the biggest mistakes departments make is treating hoarding fires like ordinary residential fires.

The increased fuel load creates enormous fire potential. Fire spread becomes unpredictable because flames travel through concealed voids created by stacked belongings. Heat release rates increase dramatically. Structural members may already be overloaded from years of accumulated weight before fire even begins attacking them.

At the same time, firefighters lose mobility. Simple tasks — advancing a line, searching a bedroom, rotating crews, or removing a victim — take considerably longer.

These realities should immediately affect risk versus reward calculations.

Recognizing hoarding conditions isn't simply about identifying a hazard. It should drive operational decisions.

Consider requesting additional companies early rather than waiting until crews become overwhelmed. Expect longer hose stretches. Anticipate slower searches. Improve accountability. Maintain strong communications between interior crews and command.

Closely monitor air consumption because navigating cluttered environments dramatically increases firefighter fatigue.

Rapid intervention crews should recognize that rescuing trapped firefighters inside a hoarding environment will likely require additional personnel and equipment.

One challenge with hoarding environments is that rescue profiles remain high.

Many occupants are elderly, live alone, or have mobility limitations. They often sleep in small pathways surrounded by combustible materials.

This creates difficult tactical decisions. The rescue profile may justify aggressive action, but firefighters must balance that against rapidly deteriorating structural conditions and limited escape routes.

Good command decisions depend on accurate information gathered during size-up.

Firefighters spend countless hours studying building construction and fire behavior. Departments should invest similar effort into recognizing hoarding conditions.

• Use photographs during company drills.
• Discuss size-up indicators during tabletop exercises.
• Walk neighborhoods with code enforcement personnel.
• Review previous incidents involving excessive storage.

The goal is simple: firefighters should recognize these clues instinctively before making entry.

The most dangerous surprises on the fireground are often the ones we fail to recognize during size-up.

Hoarding conditions rarely develop overnight. They leave clues for anyone willing to observe them.

Every firefighter should slow down long enough to read those clues, ask the right questions, and adjust tactics accordingly.

A good size-up isn't just about identifying where the fire is. It's about understanding the environment you're about to enter.

When firefighters recognize hoarding conditions early, they gain something invaluable on the fireground: time to think, time to plan, and time to put the right resources in the right place before committing crews inside.

That awareness can improve efficiency, increase firefighter safety, and ultimately make the difference between a controlled operation and one that rapidly turns into a mayday.
