Company Drill: Standpipe Operations

 

This is a great drill from a great Brother and friend, Lance Peeples of the Webster Groves Fire Department in St. Louis County.  Look for more great material from Lance in the future.

 

 

Daily Drill 1: Standpipe Operations

 

“The Daily Drill” is designed to spark discussion about operational issues in YOUR fire department.  To do this we use photographs or videos depicting fire operations in other fire departments.  We do not know the exact circumstances in which our Brothers in these fire departments are operating.  Photos or videos are not intended to embarrass our BROTHERS and SISTERS but rather are intended to provide US with learning opportunities relevant to OUR specific operational framework.  DON’TFOCUSONWHAT THEY’RE DOING…FOCUS ON WHAT YOU WOULD DO!  Stay safe!

 

Watch the video below and answer the following questions:

 

 

1.  Using the National Fire Academy Fire Flow Formula, what gpm would be required to extinguish a completely involved 500 square foot apartment fire?

How large of an undivided floor area is often found in high rise office buildings and what fire flow would be required there?

 

2.  Under previous editions of NFPA 14 what was the minimum psi required to flow 500 gpm at the most remote riser?

 

3.  What is the target gpm you are attempting to flow from your standpipe hose and nozzle combination?  What psi must be available at the standpipe operation to supply that hose and nozzle combination in order to flow your desired attack flow?

 

4.  The operation depicted showed using 4” supply line into the fire department connection.  What is the working pressure limit of LDH used in your department?  What is the elevation head pressure in a 30 story building?  Are standpipe operations usually high flow or high pressure operations?  Is using large diameter hose in FD standpipe connections a good idea?

 

 

 

 

 

 

5.  What is the diameter of hose used in your standpipe pack?  Is it an automatic/constant flow fog/smooth bore tip?  What nozzle psi is required for its designed flow?

 

6.  Will rust, scale, and other debris commonly found in standpipe systems pass through an automatic fog nozzle?  Will rust, scale and other debris usually pass through an 1 1/8” smooth bore tip?

 

7.  Can fire department pumpers ALWAYS be used to increase available pressure on the fire floor?  What about damaged or missing FD connections?  Pressure reducing and restricting valves?  Missing piping or excessive head pressures?

 

8.  At the One Merdian fire in Philladelphia on February 23, 1991 what was the length, diameter, and nozzle type (including psi/flow requirements) of the standpipe kits used by the fire department?  Did this setup work?  Why or why not?

 

9.  What were the names of the Brothers that died at One Merdian that tragic day?
