Modification History

Release 1

This version first released with CPP Property Services Training Package Release 15.0.

Supersedes and is not equivalent to CPPCLO3008 Mitigate carpet water damage.

Application

This unit specifies the skills and knowledge required to mitigate water damage to domestic or commercial structures and contents, including furnishings and personal effects by stopping the inflow of water, extracting water and drying out structures and contents, and making the site safe. It requires assessing the category of water ingress and applies to water ingress caused by an overflow of water from bathrooms and laundries, toilet backflows, sewerage, overflowing gutters, roof leaks, rising external waters and fire extinguishing activities. It includes removal of materials such as skirting boards, carpets and underlay, walls and sub-floors, selection of methods, equipment and cleaning agents suited to the task essential for performing the work safely and efficiently.

The unit is informed by aspects of standards set by the Institute of Inspection, Cleaning and Restoration Certification (IICRC) and relevant Australian Standards and applies to experienced technicians responding to jobs in commercial and domestic sites.

This unit is suitable for specialist cleaning industry personnel who use well-developed cognitive, technical and communication skills and a broad knowledge base to select and apply specialist methods, tools, materials and information in operational cleaning management contexts. They complete routine and non-routine activities and provide and transmit solutions to a variety of predictable and sometimes unpredictable problems.

All work must be carried out in accordance with relevant state/territory legislation and regulations, including work health and safety (WHS), and codes of practice as well as organisational procedures.

No licensing, legislative or certification requirements apply to this unit at the time of publication.

3.3

Treat work area with antimicrobial chemicals as needed by job, WHS and organisational requirements.

4

Evaluate outcomes of water mitigation activities.

4.1

Determine the need for post-remediation testing and, if required, arrange testing according to industry accepted practice and organisational procedures.

4.2

Determine further action or advice required based on evaluation or test results.

4.3

Conduct repeat water mitigation activities, as needed, according to organisational and job requirements.

5

Complete work activities.

5.1

Record site restoration and water mitigation outcomes and seek independent verification or sign-off, as required, according to job and WHS requirements.

5.2

Remove safety signage barriers, containment and engineering controls and dispose of soil and waste according to WHS and environmental requirements.

5.3

Clean and/or dispose of PPE as required by organisational standards.

5.4

Check equipment for faults, wear or damage and report in accordance with organisational requirements.

5.5

Store equipment and materials according to organisational requirements.
