CPPCLO4105 — Apply odour control to structures and contents

1 Inspect and assess structures and contents affected by odour.

• 1.1Clarify site access, areas to be restored and scope of work with building owner, client, insurer or supervisor.
• 1.2Select, check for fit and serviceability, and use personal protective equipment (PPE) according to WHS and job requirements.
• 1.3Identify site hazards, risks and contamination and determine control measures, including containment and engineering controls required, according to WHS requirements.
• 1.4Determine the origin and type of odour according to job requirements.
• 1.5Investigate materials and construction of affected structure and contents to determine if disposal is required or restoration is viable.
• 1.6Seek specialist advice, where required, according to job, organisational and legislative requirements.
• 1.7Document condition of area to be restored and advise client, building owner or insurer of the results of the assessment, proposed remediation methods, risks and likely outcomes and seek approval to proceed according to organisational requirements.

2 Prepare to apply odour control.

• 2.1Determine odour control methods, equipment and sequence of tasks according to job requirements.
• 2.2Position safety signage, barriers, containment and engineering controls and confirm that area is safe to access and work in according to WHS and job requirements.
• 2.3Select the required odour counteractants and appropriate equipment and check for correct operation for safe use according to manufacturer instructions.
• 2.4Determine sequence of tasks for maximum hygiene and efficiency of odour removal.

3 Apply odour control treatment.

• 3.1Pre-clean by removing as much of the source of the odour as possible, including unsalvageable debris that contributes to odour generation and recontamination of cleaned and deodorised areas, according to WHS and job requirements.
• 3.2Clean salvageable surfaces and items in order to physically remove odour-causing residue according to WHS and job requirements.
• 3.3Seal salvageable surfaces to encapsulate odour and prevent progressive recontamination according to WHS and job requirements.
• 3.4Treat remaining odour with an odour counteractant according to manufacturer instructions and WHS requirements.
• 3.5Create a deodorising fog or gas that seeks out and combines with smoke-related odour-causing substances according to manufacturer instructions and job requirements.
• 3.6Assess outcome of odour removal activities and repeat action when odour has not been removed sufficiently to meet job requirements.

4 Complete work activities.

• 4.1Record odour treatment and outcomes and seek independent verification or sign-off, as required, according to job and WHS requirements.
• 4.2Remove safety signage barriers, containment and engineering controls and dispose of soil and waste according to WHS and environmental requirements.
• 4.3Clean and/or dispose of PPE as required by organisational standards.
• 4.4Check equipment for faults, wear or damage and report according to organisational requirements.
• 4.5Store equipment and materials according to organisational requirements.

What does an assessment tool for CPPCLO4105 need to cover?

To satisfy the Principles of Assessment and Rules of Evidence, an assessment for CPPCLO4105 needs to address all 103 unit components: 4 elements with 22 performance criteria, 6 performance evidence requirements, 75 knowledge evidence requirements, and the foundation skills. A coverage matrix mapping each question and task to these components is what an auditor looks for.

How does Auditori generate an assessment tool for CPPCLO4105?

Auditori pulls the current release of CPPCLO4105 from training.gov.au and generates a complete package: candidate assessment, assessor guide with model answers and observation criteria, and a coverage matrix mapping every component. A suitably qualified person then reviews and approves the draft in a built-in workflow — consistent with ASQA's guidance on AI use in VET — before export as branded PDF and editable Word.

Is the first assessment tool really free?

Yes. Every new account includes one free credit — enough to generate the complete assessment tool for CPPCLO4105 — with no card and no subscription required. After that it's pay-as-you-go per unit.

Can I check my existing CPPCLO4105 assessment instead of generating a new one?

Yes — upload your existing assessment or learner guide and Auditori maps it against every element, performance criterion, PE and KE of CPPCLO4105, showing exactly what's covered and what's missing. Mapping costs a quarter of a credit.
