Sample D: Monitoring Practice For Dump Tank Water   

Written practice for:

Maintaining and monitoring dump tank water for apples coming out of cold storage

Who needs to do it:

Workers responsible for task

How often it should be done:

Initially before using the dump tank water and several times during the day

Why you are doing it:

To ensure chlorine levels are sufficient to maintain water quality

Tools and equipment used

(if applicable):
  • 12% sodium hypochlorit
  • pH test stripFree chlorine test strips

Step-by-step instructions:
  1. Fill dump tank with water.
  2. Add 1 L sodium hypochlorite for 1,000 L of water (to create 120 ppm solution) and mix well.
  3. Test for free chlorine:
    • Initially when you first make up the solution you will have to dilute the sample due to limitations on the free chlorine test strip.  Remove 1 mL of chlorinated water and dilute with 9mL distilled water.  (Note: a 1:100 dilution may be necessary for the initial testing.)
    • Using dry hands, dip the chlorine test strip into the water.  Compare it to the colour chart and record the free chlorine level.
  1. Test for pH:
    • Dip a new pH test strip for 1-2 seconds in the dump tank water and then compare it to the colour chart.  Record the pH.  It should be between 6.0 and 7.5.)  If the pH is too high, add acid.

 Throughout the day:

  1. Use dump tank water that is slightly warmer than the cold storage temperature for the apples.
  2. Test and record the level of free chlorine halfway through the day OR when the product is unusually dirty.
  3. Add sodium hypochlorite as required to maintain a level of at least 25 ppm free chlorine.

    b) Subcutaneous injection: Use ½-¾" x 18-20 gauge needles for pigs less than 4.5 kg (10 lbs); ¾-1" x 16-18 gauge needles for pigs over 4.5 kg. (10 lbs).
  2. Follow the instructions on the label of the medication being injected.
  3. Restrain pigs prior to and during injection using your hands, a sorting board or a snare, depending on the size of the animals.
  4. Apply alcohol to disinfect the injection sited.
  5. Inject medication in the neck in the area behind the ear and in front of the shoulder.
  6. After each injection, inspect the needle for damage and change it if it is bent, dull or contaminated with manure, or at least after injection of every litter or every ten pigs.
