Tips for gathering evidence to demonstrate your skills

The important thing to remember when gathering evidence is that the more evidence the better - that is, the more evidence you gather to demonstrate your skills, the more confident an assessor can be that you have learned the skills not just at one point in time, but are continuing to apply and develop those skills (as opposed to just learning for the test!). Furthermore, one piece of evidence that you collect will not usualy demonstrate all the required criteria for a unit of competency, whereas multiple overlapping pieces of evidence will usually do the trick!

  2. Valves on outlet manifold are opened and connected with flexible pipes to waste storage facility or recycling tanks for tank cleaner
  3. All hatches are opened, spray balls are placed into tanks after visually checking tank condition, and solid materials present are washed out with high pressure water, prior to starting cleaning cycle
  4. Tank is rinsed, washed with tank wash until waste is clear and recycled into a holding tank for reuse, leaving tanker tank to drain
  5. Water in holding tank is topped up, ph is tested and solution is replaced as required in accordance with workplace procedures
  6. Tank is rinsed with water in short bursts until liquid leaving tank is clear
  7. Top of tank is hosed off again with water, and spray balls are removed
  8. Tank is visually checked through hatches with a torch, for cleanliness
  9. When cleanliness standards have not been achieved, tanker is rewashed or re-rinsed as required and hatches are closed
  10. At conclusion of cleaning operations, drainage hoses are removed, manifold is checked for cleanliness, and drainage valves are closed and sealed to indicate completed process in accordance with workplace procedures
