Course: Tanker operations in water supply

Session Reference: 1-1

Time Required: 3 Hours

Materials Required: Engines, tankers, various water sources, portable water tanks,

Motivation:

It is important for companies able to obtain water from sources other than hydrants at the fireground, and operate a tanker shuttle to provide adequate water supply for firefighting operations. This skill is not limited to rural applications, and may be necessary to supplement hydranted areas where there is inadequate water supply.

Objective (SPO): 1-1

Given information from discussions, handouts, and reading materials demonstrate the operation of rural tanker water supply operation according to the standards of the authority having jurisdiction.

Overview:

Tanker operations in rural water supply

  1. Selecting Water Sources

  2. Tanker Features

  3. Selecting Tanker Travel Routes

  4. Tanker Fill and Dump Station operation

  5. Calculating and Meeting Water Flow Requirements

  6. Increasing Water Amounts

Enabling Objectives: 1-1

1-1-1

Choose the best water source available to support a fireground operation.

1-1-2

Identify the features of a tanker that aid in delivering water to the fireground.

1-1-3

Select a route of travel for tankers involved in the shuttle operations.

1-1-4

Setup and operate a tanker fill station and dump station.

1-1-5

Determine the water flow that can be sustained on the fireground while the tanker shuttle is operational.

1-1-6

Make recommendations for increasing the amount of water available at the fireground if necessary.

1-1-7

Demonstrate tanker operation in practical evolutions

         Note: areas used for practical drill will likely have to be established prior to class start by

         instructors/officers. Have students share knowledge on these selections as the class progresses,

         for improvements

 

I. Selecting Water Sources

A. Types of water sources

  1. Hydrants

  2. Ponds/lakes

  3. Streams

  4. Rivers

  5. Swimming Pools

  6. Others

B. Items to consider when selecting a water supply source

  1. Accessibility of the source

      a. Accessible all year?

      b. Water always available (does stream dry up in summer?)

  2. Distance from the fire

  3. Route of travel

  4. Time required to travel route

  5. Easy access for multiple tankers

 

II. Tanker Features

A. Tank size

  1. Large volume tank

  2. Minimum tank size established by local AHJ.

  3. Easy to fill quickly

      a. Direct fill to tank

      b. Tank properly vented

B. Methods for offloading water

  1. Direct to tank gravity dumps

  2. Jet dumps

  3. Pump off

C. Other equipment

  1. Drafting sleeves

  2. Portable dump tank(s)

  3. Portable pump capable of drafting

 

III Tanker Travel Routes

A. Distance to water source

B. Road type/conditions

C. Can route be established so tankers do not pass each other? (circular route)

D. Intersections

E. Traffic volume on roads

F. Obstructions (restricted bridges, low clearances, etc)

G. Time required to complete full route

H. Weather

 

 

IV. Tanker Fill and Dump Station Operations

A. Tanker fill site

  1. General considerations

      a. Easily accessible by all tankers

      b. Large enough to support operation

      c. Safe from other traffic

      d. Reasonable distance from fireground/dump site

  2. Operations

      a. Allow room for draft pumper if necessary

      b. Establish multiple lines to fill tankers

      c. Fill only one tanker at a time

      d. Have adequate personnel available to safely manage fill site responsibilities

            1. Pump operator

            2. Hose handlers

            3. Traffic control

B. Tanker dump site

  1. General considerations

      a. Easily accessible by all tankers

      b. Large enough to support operation

      c. Safe from other traffic

      d. Does not block access to fireground for other apparatus

C. Operations

  1. Allow room for fireground supply pumper

  2. Allow room to store water on the scene
