High-Rise Firefighting Operations: Strategy, Logistics, and Common Mistakes

High-rise firefighting is a different animal. Everything that is straightforward on a residential fire becomes complicated when you stack it vertically. Your water supply depends on standpipe systems that may or may not work properly. Your access is limited to stairwells and elevators, and both present hazards. Your attack crews are exhausted by the time they climb to the fire floor with their equipment. Your communication is degraded by concrete and steel. And your incident command structure needs to expand rapidly to manage operations on multiple floors simultaneously.

If your department protects any buildings over 75 feet, and that is the general threshold where most codes define a high-rise, you need to train specifically for high-rise operations. The skills that make you effective on a single-family house fire are necessary but not sufficient. High-rise firefighting requires additional knowledge of standpipe systems, elevator operations, stairwell management, staging logistics, and multi-floor coordination.

NFPA at nfpa.org publishes NFPA 1 Fire Code, which includes specific requirements for high-rise buildings including standpipe systems, fire alarm systems, emergency voice communication, fire command centers, and elevator recall. Understanding these code requirements helps you know what should be present in a high-rise building and how to use those built-in systems to your advantage.

Standpipe Operations

In a high-rise fire, you are not stretching hoseline from the engine to the fire. You are connecting to the building's standpipe system and stretching from the standpipe outlet to the fire apartment or floor. This means your water supply depends entirely on the standpipe system functioning correctly.

Standpipe systems in older buildings are frequently problematic. Pressure-reducing valves may be set too low, giving you inadequate flow at the nozzle. Caps on standpipe outlets may be painted shut or corroded. The system itself may not have been tested or maintained in years. In some older buildings, the standpipe system is a dry system that requires the fire department to supply it from a fire department connection at street level.

Before you connect to a standpipe outlet, know what you are working with. Check the pressure at the outlet. If the building has pressure-reducing valves, you may need to adjust them or remove them entirely. Carry a standpipe kit that includes a 2.5-inch to 1.5-inch reducer, a pressure gauge, wrenches for the outlet connection, and extra gaskets.

Connect on the floor below the fire. This is the standard for standpipe operations. You connect one floor below and stretch up the stairwell to the fire floor. This keeps your connection point in a tenable environment while you operate on the fire floor above.

The Stairwell Problem

Stairwells in a high-rise building serve multiple critical functions simultaneously, and managing them is one of the biggest challenges of high-rise operations. The stairwells are your primary access route for fire attack crews climbing to the fire floor. They are the primary evacuation route for building occupants coming down. They are your staging area for equipment and personnel. And they are your emergency egress route if conditions deteriorate.

That is a lot of competing demands on a narrow stairwell. If you do not manage stairwell usage deliberately, you end up with exhausted firefighters climbing past panicking occupants, equipment getting stuck on landings, and nobody able to move efficiently in either direction.

The solution is stairwell designation. Assign specific stairwells for specific functions. The attack stairwell is used by fire attack crews to access the fire floor. Ideally, this is the stairwell closest to the fire apartment. The evacuation stairwell is used by building occupants to exit the building. This should be the stairwell farthest from the fire or the one that provides the cleanest air and most direct path to the exit.

If the building has only two stairwells, which is common, you may need to share the attack stairwell between crews ascending and occupants descending. In this case, establish a traffic pattern: crews ascending stay to the inside of the stairwell, occupants descending stay to the outside. It is not ideal, but it is manageable with discipline.

Staging and Logistics

High-rise fires are won or lost on logistics. You can have the best attack crew in the world, but if they arrive on the fire floor without enough air, without the right tools, and without water flowing from the standpipe, they are ineffective.

Establish a staging area two floors below the fire floor. This is where additional crews assemble, equipment is stockpiled, and crews rotating off the fire floor can rehabilitate. The staging officer manages this area and sends crews to the fire floor as needed by the attack team leader.

Everything the attack crew needs must be carried up the stairs or sent up by elevator. This includes high-rise hose packs, usually 150 feet of 1.75-inch or 2-inch hoseline in a compact bundle, forcible entry tools, extra SCBA bottles, and the standpipe kit. Each crew member should carry their own equipment plus one additional item.

The logistics of getting equipment to the fire floor is physically demanding. Climbing multiple flights of stairs in full gear with a hose pack and tools is exhausting, and the crews that arrive on the fire floor need to be able to work. Build in rest periods. Rotate crews frequently. Do not send a crew to the fire floor if they are already gassed from the climb. They will not be effective, and you will be adding to the rescue problem rather than solving the fire problem.

Elevator Use

Elevators can dramatically reduce the physical demands of high-rise operations, but they present their own hazards. The general rule is to use elevators only to transport personnel and equipment to the staging floor, never to the fire floor itself.

Before using an elevator, confirm that it is operating under fire department recall. Most modern high-rise buildings have Phase I recall, which sends all elevators to the ground floor when the fire alarm activates, and Phase II firefighter service, which allows firefighters to operate an individual elevator car using a special key. Only use elevators in Phase II firefighter service mode.

Never take an elevator to the fire floor. If the fire is on the 14th floor, take the elevator to the 12th floor and walk up. Elevator shafts act as vertical channels for heat and smoke, and an elevator car that opens its doors on a fire floor can expose occupants to immediately untenable conditions. There have been multiple incidents where firefighters died after an elevator opened on the fire floor.

Check the elevator shaft for smoke before entering the car. If you see smoke in the shaft or feel heat at the elevator doors, do not use that elevator. Take the stairs.

Communication Challenges

Radio communication in high-rise buildings is notoriously difficult. Concrete floors, steel reinforcement, and the sheer distance between the command post at street level and crews operating on the 20th floor can degrade radio signals to the point of uselessness.

Many high-rise buildings have in-building radio amplification systems, sometimes called BDA systems or bi-directional amplifiers. These systems are required by code in newer buildings and some jurisdictions have required retrofitting in older buildings. If the building has one, use it. If it does not, you need a backup communication plan.

One common solution is to position a firefighter on the floor below the fire as a communication relay point. This person receives radio traffic from the attack crew on the fire floor and relays it to the incident commander. It is not ideal, but it works when direct radio communication fails.

Fire command centers in modern high-rises often include public address systems, telephone communication systems, and annunciator panels that show the status of fire alarms and sprinklers throughout the building. Use these systems. They are there for exactly this situation.

Common Mistakes in High-Rise Operations

Several mistakes recur in high-rise operations, and all of them are preventable with training and discipline.

Failing to establish water supply before sending crews to the fire floor. If the standpipe system is not charged and flowing before the attack crew connects their hoseline, they are operating without water. Confirm water supply at the fire department connection and verify flow at the standpipe outlet on the floor below before committing to the attack.

Sending too many people to the fire floor. The fire floor is a confined operating space. More people does not mean more progress. It means more air consumption, more congestion, and more potential victims if conditions deteriorate. Send only the crews needed for the current tactical assignment.

Failing to control building HVAC systems. Heating, ventilation, and air conditioning systems in high-rise buildings can move smoke throughout the structure. The HVAC system should be shut down or managed by the building engineer in coordination with the incident commander to prevent smoke spread to uninvolved floors.

Neglecting rehab for crews. The physical demands of high-rise operations are extreme. Climbing stairs in full gear, operating in high-heat environments, and the extended incident duration combine to create significant risk for heat exhaustion and cardiac events. Establish a rehab area and enforce mandatory rest periods for crews rotating off the fire floor.

High-rise firefighting demands planning, training, and operational discipline that goes beyond normal structure fire operations. If your district has high-rise buildings, your department needs to train specifically for this environment. Walk the stairwells. Inspect the standpipe systems. Practice your hose stretches. Know the building before the fire.
