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!

Prepare to use portable gas detection device.
|
|
The need to initiate gas detection is identified by OHS requirements and established procedures. Completed |
Evidence:
|
The gas or vapour to be detected is established from plant/site records or consultation with relevant personnel. Completed |
Evidence:
|
Gas detection device(s) for the gas/vapour to be detected is/are checked for calibration and response in accordance with manufacturer instructions. Completed |
Evidence:
|
Gas detection devices are checked for factors that could nullify the Ex rating. Completed |
Evidence:
|
Note: |
|
Completed |
Evidence:
|
This would include damaged casing, use of incorrect batteries and/or chargers, use of incorrect spare parts and accessories. |
|
Completed |
Evidence:
|
Establish safety of the area with regards to the presence of gases or vapours.
|
|
OHS policies and procedures relating to gas/vapour detection are followed. Completed |
Evidence:
|
Gas detection device is used in accordance with manufacturer instructions and with regards to environmental conditions. Completed |
Evidence:
|
Observations of gas detection readings are recorded in accordance with established procedures. Completed |
Evidence:
|
Safe-to-work is determined from gas detection reading and then clearance to work is issued in accordance with established procedures. Completed |
Evidence:
|
Monitor gas detection devices for the presence of gases/vapours.
|
|
The frequency of monitoring is determined from the nature of gas/vapour and the effect of environmental and local conditions (e.g. ambient temperature rise, density of gas/vapour, flash point, dew point and detector position). Completed |
Evidence:
|
Others are instructed in procedures to carry out monitoring and these instructions are documented. Completed |
Evidence:
|
Follow procedures to maintain gas detection devices.
|
|

Evidence:
|
Gas detection devices are formally checked and calibrated periodically in accordance with established site requirements and instrument accuracy. Completed |
Evidence:
|
Storage, use and calibration record of the gas detection devices is maintained, in accordance with the established procedures. Completed |
Evidence:
