SECTION II. INTRODUCTION

Method of Instruction: Conference / DiscussionInstructor to Student Ratio is: 1:18Time of Instruction: 0 hrs

Media: Group-paced Instruction

MotivatorThe ability of the water treatment specialist to properly shut down the TWDS hoseline is a very important step prior to dismantling and preparing the TWDS formovement.

TerminalLearningObjective

NOTE: Inform the students of the following Terminal Learning Objectiverequirements.

At the completion of this lesson, you [the student] will:

Action: Shut down the TWDS, perform after-operations PMCS, makeappropriate entries on DA Form 2404 and correct any deficiencies,and observe environmental considerations.

Conditions: Given a demonstration, a training site, POL, a TWDS, DA Form2404, a GO/NO GO checklist, a hands-on practical exercise, andTM 10-4320-303-13.

Standards: In accordance with TM 10-4320-303-13.

SafetyRequirements

1. Exercise extreme care and safety in handling the TWDS. Carelessness inhandling the system could result in damage to the equipment and injury to

personnel.

2. When handling equipment, always remove rings, bracelets, wrist watches, andany other jewelry prior to working with the system. Jewelry can catch onequipment and cause injury or may short circuit across electrical circuits andcause burns or electrical shock.

3. The exhaust system on the pump engine can become very hot duringoperations. Be careful not to touch it with bare hands.

4. The radiator also gets extremely hot during operations. Let it cool down beforechecking fluid.

5. To prevent injury, be careful not to short out the batteries on the pump. Do notsmoke or use open flames near batteries or fuel tank.

6. To prevent air compressor assembly from rolling or sliding, securely lock theparking brakes.

7. Do not operate engine around open fuel.

8. Never refuel hot or running engines. Avoid overfilling the fuel tank.

9. Wear hearing protection when within 50 feet of operating air compressor.

10. The hypochlorination unit weighs over 200 pounds. At least four people areneeded to lift it to prevent personal injury or damage to the equipment.

11. Hypochlorite solution is toxic to skin and eyes. If calcium hypochlorite comes

into contact with skin or eyes, flush right away with water. Seek medical help.

12. Store calcium hypochlorite in a cool, dry place. Keep container closed.

13. Do not allow calcium hypochlorite to mix with any other materials, such asfuels, oils, paint products, or ammonia. This may cause fire or hazardousgases. Mix only in accordance with directions for use.

14. The hypochlorinator contains water under high pressure during and afteroperation. If this pressure is not relieved before working on the unit, seriousinjury may occur.

15. If hypochlorinator stops working properly or residual test does not give

satisfactory reading, immediately shut down operation of distribution point,notify your supervisor, and take corrective action.

16. Portable radios will be required for communication and safe set-up.

EnvironmentalConsiderations

Army Regulation 200-1 delineates TRADOC responsibilities to integrate

environmental requirements across DTLOMS and ensure all training procedures,materials, and doctrine include sound environmental practices and considerations.The Army's environmental vision is to be a national leader in environmental andnatural resource stewardship for present and future generations as an integral partof all Army missions. This Training Support Package meets this standard.

EvaluationRefer students to the Student Evaluation Plan.

InstructionalLead-In

The ability to shut down the TWDS hose line, combined with the ability to lay outand operate the TWDS hose line, is essential for the water treatment specialistwhen utilizing the TWDS hose line to store, distribute, and transport potable water.
