standpipe

Question 1

Where are standpipe systems primarily found?

Answer 1

• High-rise buildings
• Large area buildings
• Bridges
• Tunnels
• Parking garages

Standpipe systems can also be found in various structures to facilitate fire suppression.

Question 2

What should you look for to identify standpipe connections?

Answer 2

Markings or labeling

Standpipe connections and sprinkler connections may look similar and can be grouped together.

Question 3

What type of buildings may have standpipe systems?

Answer 3

• Large open space office buildings
• Two-story buildings

These systems can make moving lines easier than deploying from the apparatus.

Question 4

What are the two types of standpipe systems mentioned?

Answer 4

• Dry systems
• Wet systems

Dry systems are commonly used in facilities open to the weather.

Question 5

When operating at structures with separate Fire Department Connections (FDC), what should be pumped first?

Answer 5

Standpipe

This ensures that the standpipe system is operational before the sprinkler system.

Question 6

What is the recommended hose size to supply a Siamese FDC?

Answer 6

21⁄2” supply hose

Both supply inlets should be fed with this size hose.

Question 7

What is the purpose of a standpipe pack?

Answer 7

To perform standpipe operations

A standpipe pack should be brought into standpipe equipped structures on every alarm.

Question 8

What are the three classifications of standpipe systems?

Answer 8

• Class I
• Class II
• Class III

Each class has different connections and intended users.

Question 9

What is the main feature of Class I standpipe systems?

Answer 9

21⁄2” connections for heavy streams

Designed solely for use by trained fire suppression personnel.

Question 10

What do Class II standpipe systems provide?

Answer 10

• 11⁄2” connections
• Outlets for building occupants
• Racks or reels of hose

These systems are commonly referred to as “House Lines.”

Question 11

What components are included in a Warwick Fire Department standpipe pack?

Answer 11

• Bag
• 2 1⁄2” slow-close valve
• 8’ x 2 1⁄2” leader line
• High-rise wye with gauge
• Two spanner wrenches
• 6” vice grips
• Aluminum pipe wrench
• 2 1⁄2” to 1 1⁄2” coupling reducer

These components are essential for effective standpipe operations.

Question 12

When deploying a standpipe pack for a fire, where should it be connected for floors above grade?

Answer 12

One floor below the fire floor

This allows for optimal positioning of the hose line for the attack.

Question 13

What should be done with the fire floor attack stairwell door during operations?

Answer 13

Chocked in the full open position

This keeps the stairwell clear for other tactics.

Question 14

What is the first step in supplying and pumping an FDC?

Answer 14

Lay a supply line from the hydrant to the FDC location

This is crucial for establishing water supply for fire operations.

Question 15

What should be checked after removing caps from the FDC?

Answer 15

Check for damaged threads or debris

This ensures a proper connection for pumping operations.

Question 16

What pressure should be produced at the discharge of a solid bore nozzle during standpipe operations?

Answer 16

50 psi

This is a standard requirement unless specific pressure restrictions are posted.

Question 17

True or false: Car fires in parking garages require at least two Engine Companies.

Answer 17

TRUE

One Engine Company advances a handline off a standpipe riser while another pumps the system.

Question 18

What is a potential issue when pumping dry standpipe systems in parking garages?

Answer 18

Water flowing unchecked

This can occur if standpipe discharge valves are open, stealing water and pressure from needed areas.
