Flashcards

Standpipe-equipped buildings

Larger buildings (typically over 75ft tall or with more than 2 stories and over 20,000 sq ft per floor) often have standpipes for firefighting.

Standpipe operations

Fighting fires in standpipe-equipped buildings involves a specific plan that differs from typical hose-stretching methods.

Pre-fire planning

Knowing which buildings have standpipes before a fire helps firefighters prepare a strategy.

Identifying standpipes

Determining if a building has standpipes is crucial in fire response planning.

Fire response plan

A plan that details precisely how to fight a fire based on building characteristics (e.g., standpipes vs. no standpipes).

Standpipe use at fires

Using a standpipe at a fire is not always necessary and can be slower than using a fire truck's hoseline directly.

Ground floor fires

For ground-floor fires, stretching a hoseline from the fire truck may be faster and more efficient than using the standpipe.

Handline operations

Using a regular hoseline, called a handline, often involves a faster setup compared to standpipe connections.

Fire access points

Evaluating how close the fire is to access points, such as doors or windows, is vital for choosing the best hose line setup.

Standpipe assessment

Determining how a standpipe will factor into firefighting strategy requires a thorough assessment of the fire's position and accessibility.

Standpipe system advantage

Using a standpipe system in firefighting often allows the attack team to reach the fire more easily even though they have to pass the fire, as it simplifies the hose layout and saves time.

Standpipe location for fire above the second floor

For fires situated above the second floor, connecting to the standpipe system is often a faster and more efficient way to reach the fire due to reduced hose length and friction losses.

Standpipe verification before deployment

Before deploying a hose, the attack team should confirm the precise fire location and assess if the standpipe hose is long enough to reach the fire.

Standpipe hose length assessment

The fire location, distance, and the building's layout dictate the required hose length, which can be determined rapidly by evaluation of the ladder crew or the hoseline officer.
