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!

DEFPHL007 - Conduct chlorine dosing of water at the point of supply

What evidence can you provide to prove your understanding of each of the following citeria?

Prepare and conduct chlorine dosing

  1. Use, handle and store chlorine in accordance with safety data sheet and organisational procedures
  2. Establish chlorine residue level in accordance with operational field water testing procedures
  3. Determine chlorine demand by comparing chlorine residue level with ADWG and chlorine concentration
  4. Select, fit and use appropriate personal protective equipment
  5. Conduct chlorine dosing at the point of water supply, as required in accordance with ADWG and organisational procedures
  6. Monitor chlorine dosing to achieve desired chlorine residue level
  7. Identify dosing faults and carry out corrective actions in accordance with operational procedures
Use, handle and store chlorine in accordance with safety data sheet and organisational procedures
