Q

What are the DOUBLE-jacketed RUBBER lined hoses on the department? What PSI are they tested at?

A
  • Handlines: 1”, 1 1/2”, 1 3/4”, and 2 1/2” : 400 psi

- By-passes and Soft Suctions: 300 psi

17
Q

What are the SINGLE-jacketed synthetic nitrile rubber lined hoses on the department? What PSI are they tested at?

A
  • 2” high rise, 2 1/2” high rise pigtails and 3” ladder pipe hose: 300 PSI
  • 4” supply lines : 250 PSI
18
Q

What re the SINGLE- jacketed THERMAL PLASTIC line hoses on the department? What PSI are they tested?**

A
  • brush hose: 300 PSI
    • Due to its light weight construction, recommended hose be tested on grass or light fuel bed surfaces to prevent damage to outer jacket.
19
Q

What is the duration of the hose testing?

A

5 minutes

20
Q

What is done to determine if coupling or collar have slipped during testing?
