Study Notes
Turbo Draft Overview
- Standard drafting is preferred for its larger water volume availability.
- Turbo Draft is utilized when standard drafting access is inadequate.
- It operates up to 200 feet away and can generate water flows of 670 gallons per minute (gpm).
Equipment Requirements
-
Turbo Draft Equipment:
- 3” hose (up to 200 feet)
- 5” hose (up to 200 feet)
- Spanner wrenches (large and small)
- Buoy or roof ladder (for open water use)
-
Turbo Draft CS Specific Equipment:
- 6” hard suction hose and strainer (for field well use)
- Well pipe (for field well use)
- Rubber mallet (for sealing connections)
Riding Positions on Suppression Apparatus
- #1: Unit Officer-in-Charge (OIC)
- #2: Driver/Operator (D/O)
- #3: Firefighter (FF) behind D/O
- #4: FF behind Unit OIC
Drafting Evolution Procedure
-
Arrival:
- OIC evaluates the best location for Turbo Draft.
- D/O positions apparatus as close as possible to the water source.
- FFs check for obstacles impeding drafting.
-
Set Up (Open Water Use):
- Buoy Deployment:
- Maintain parallel hose layout to prevent appliance shifting.
- Deploy Turbo Draft in 2 to 3 feet of standing water or 1 to 1.5 feet of moving water.
- Roof Ladder Deployment:
- Preferred for steep embankments; provides better control during placement.
- Buoy Deployment:
-
Field Well Use with Turbo Draft CS:
- Ensure hoses are parallel to maximize flow.
- Properly seal connections to avoid air leaks, using a rubber mallet if needed.
Establishing the Draft
- Engage pump and open tank-to-pump valve.
- Maintain 175 PSI engine discharge pressure to ensure adequate water supply.
- Monitor and adjust connections to prevent kinks in hoses.
Pumping Operations
- Maintain pressure on the Turbo Draft 3” hoseline.
- Monitor the supply line flow closely to prevent collapses, especially with Aerial and Ladder trucks.
Clearing the Strainer
- Close other discharges except the Turbo Draft line.
- Back up water flow in the strainer by slowly closing the ball intake valve (BIV) to clear debris.
Tandem Turbo Draft Setup
- Set up two Turbo Draft units for enhanced flow rate.
- Charge the second unit's supply line from the first.
Maintenance Best Practices
- After use, flush all components with clean water.
- Remove debris and ensure the screen is unobstructed to maintain function.
Turbo Draft Location
- Currently carried by units: E04, E37, L46, E55, E57, E58, E61, E65, L66.
- Turbo Draft CS locations include units: E05, E06, E16, E43, WT16, T52, T60.
