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!

Steam clean a tanker

  1. The vehicle is earthed to prevent sparks and explosions

  3. All access points, including vents and washing points, are opened and heat-sensitive auto fill probes removed in accordance with workplace procedures
  4. Where the tank has held oil/diesel, a wash consisting of detergent wash and hot water rinse is carried out followed by the application of steam
  5. Where the tank has only held petrol, a steam clean only is carried out in accordance with workplace procedures
  6. After the wash, the unit is left to drain until liquid ceases to drain from the outlet valves and steam stops leaving the vents on the top of the tank
  7. All vents and valves are closed and the auto fill probes reconnected
  8. Plastic seals are placed on valves to signify the completed cleaning of the tanker where required in accordance with workplace procedures

Clean a tanker using water and detergent

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