TFD Engine Captains
Who shall be responsible for:
- Repairing 5” supply hose in accordance with the guidelines set forth in this document
- Replacing hose in accordance with the guidelines set forth in this document
- Ensuring there is an adequate supply of 1-¾” hose at Station 2 for emergency replacement when Station 2 personnel are not available
TFD Station 2 personnel
TFD Captains shall assign personnel to test at least annually all of the following hose carried by his/her company to increase the reliability of hose performance at an emergency incident:
a. 1” wildland hose
b. 1 ¾” hose
c. 2 ½” hose
d. 5” hose
Service test pressures shall be:.
a. 300 psi for attack lines
b. 200 psi for 5” supply lines
All TFD hose testing shall be conducted using an approved hose testing machine.
True or false?
True.
Fire engine pumps shall not be used for hose testing.
The maximum amount of hose to be tested at one time is _______.
300 feet.
Hose testing shall be conducted in an area without hazards that may endanger personnel or damage hose and that:
a. Is large enough to lay 300 feet of hose in a straight line without bends or kinks
b. Has a dedicated water source
The stabilization period for hose testing shall be not less than _______.
one minute per 100 feet of hose in the test layout.
A hose shall be considered to have failed testing if:
a. There is coupling slippage during testing
b. The test layout does not hold for three minutes without leaking
TFD personnel shall to what when hose testing?
a. Wear proper PPE at all times while testing hose
b. Wash and place back on the apparatus all hose that passes testing
c. Remove hose from apparatus and reload it so that folds occur at different positions to prevent damage to hose lining
d. Mark and tag with an explanation all hose sections that fail testing
e. Remove hose sections that fail testing from service and send to Station 2 for repair or replacement
f. Document hose testing on FIR 308 and in the Apparatus Log Book
How much hose shall be available at Station 2 for emergency replacement in the event that Station 2 personnel are unavailable.
Four 100-foot sections of 1 ¾” hose
TFD Engine Captains shall maintain:
a. Hose inventory (FIR 334) on apparatus assigned to his/her station
b. Company hose testing schedule
c. Company records related to hose testing (FIR 308)
i. Copies of the FIR 308 shall be maintained in the company file for the life of the hose
Approved hose testing machines are available from:
a. Station 2
b. Station 8
c. TFD Training Center
When the hose pressure exceeds _______ during testing, all TFD personnel shall clear the hose testing area except for those required to perform the remainder of the hose testing procedure.
45 psi
TFD personnel shall not stand:
a. In front of the free end of the hose
b. On the right side of the hose
c. Closer than 15 feet on the left side of the hose
Some lesser known steps in the hose testing process:
Secure the hose directly in back of the test cap to avoid whipping or other uncontrolled movement in the event of a hose burst.
a. Two 100 foot bundles of 2-½“ hose or equal is recommended
With the hose at 45 psi, check for leakage at each coupling.
Raise the hose pressure slowly, at a rate not to exceed 15 psi per second, until service test pressure is attained and maintained for the duration of the stabilization period (one minute per each 100 feet of hose).
After the stabilization period, hold the service test pressure in the hose layout for another three minutes without further pressure boosts.
Example: 300 feet of hose will require 3 minutes of stabilization and 3 minutes of service test pressure.
Check for coupling slippage after the layout has been drained.
- Forward the copies of the FIR as follows: a. Original (white) copy to the Station 2 Captain b. Pink copy in the company file.
How do you mark damaged areas on hose?
Use a grease pencil, not rags, to mark the damaged area(s).
Fill out a repair tag with the following information:
a. To: Station 2
b. From: Company sending hose in for repair or replacement
c. Brief description of the problem
d. Date problem was detected
Affix the repair tag to the damaged hose.
Send damaged or failed hose, with repair tag attached, to Station 2 as follows:
a. Attack hose via messenger
b. 5” supply hose via the requesting company
How is hose repaired?
- Repair only 5” hose by removing the damaged sections and installing couplings.
- Do not patch small diameter hose.
