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.
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.
