Respiratory protection
Full mask guideSelect for the hazard, never by appearance
Possible hazards
- wood, gypsum, fibre or debris dust
n95 or better if assessedhepa capture
Priority controls
- Eliminate or reduce dust/vapour at the source before relying on a respirator.
- Use appropriate wet methods, HEPA capture, local exhaust and isolation.
- Read the SDS and exact product instructions.
What is not sufficient
- The respirator does not replace source extraction and HEPA cleanup.
Stop if
- Stop if the contaminant is unknown, air is inadequate, a seal is impossible or symptoms occur.
Final selection depends on contaminant, concentration, SDS, fit and the applicable program. An air-purifying respirator does not supply oxygen.

Complex interior fit-out
Yellow describes technical complexity, not legal permission. Verify permits, inspections and trade requirements in your province, territory and municipality before starting.
Important limit
This guide helps prepare and oversee the project. Required plans, permits, inspections, manufacturer instructions and professionals prevail.

Permit and inspection questions
Controlled sequence
Detailed stages and hold points
Each stage states who may act, what to verify and what evidence to retain.
1
Before work
Define scope, permits and responsibilities
A verifiable scope prevents surprise exclusions and uninspected concealed work.
Substeps
- Photograph initial conditions, damage, interfaces and access before any demolition.
- Write down scope, exclusions, exact materials, method and acceptance criteria.
- Confirm permits, utility locates, notifications and inspections before ordering or demolition.
- Measure walls, floors, ceilings, openings, appliances and services; record variations.
- Confirm loads, anchors, clearances, access and interaction with electrical or plumbing systems.
- Approve sample, colour, layout, joints and hardware before fabrication or cutting.
Homeowner role
Prepare measurements, photos, questions, comparisons and administrative checks.
Qualified role
Confirm method, technical details, inspections and responsibility limits.
Quality check
Contract, plans, products, inspections, exclusions and acceptance criteria are identifiable.
Hold point
Do not order non-returnable products or demolish before this validation.
Stop if
The quote does not describe method, products, permits or unforeseen conditions.
Evidence to keep
Signed scope, plans, emails, permit or written authority confirmation.
2
Execution
Inventory stored items, weight, dimensions and access frequency
A clear scope prevents wasted purchases and rework.
Substeps
- Inventory stored items, weight, dimensions and access frequency.
- Read the exact product data sheet and note limits, wait times and application conditions.
- Measure existing conditions in more than one location and record variations before buying.
- Allow for waste, accessories, delivery, disposal and a modest contingency.
- Dry-fit and confirm alignment, operation and access before permanent fastening.
- Photograph this point and record product, measurement or result before proceeding.
Homeowner role
The homeowner can generally prepare, measure, document and verify, provided no regulated system is opened or modified.
Qualified role
Load-bearing wall, regulated service, hazardous material surface or specialized fabrication.
Quality check
Scope, quantities and sequence are written down before work starts.
Hold point
Do not conceal or pay this milestone before verification and photos if this work will become hidden.
Stop if
Stop if the scope affects structure, a regulated system or an unevaluated suspect material.
Evidence to keep
Overall photo, close-up detail, product used and relevant measurement or test.
3
Execution
Locate framing, hidden services and clearances for doors, vehicles, appliances
A starting error repeats across the entire installation.
Substeps
- Locate framing, hidden services and clearances for doors, vehicles, appliances and exits.
- Measure each dimension at least twice and verify square, level or slope as appropriate.
- Mark reference lines independent of walls that may be irregular.
- Dry-fit the first pieces and adjust the layout to avoid an overly narrow final piece.
- Dry-fit and confirm alignment, operation and access before permanent fastening.
- Photograph this point and record product, measurement or result before proceeding.
Homeowner role
The homeowner can generally prepare, measure, document and verify, provided no regulated system is opened or modified.
Qualified role
Load-bearing wall, regulated service, hazardous material surface or specialized fabrication.
Quality check
Marks are visible, consistent and confirmed by a second measurement.
Hold point
Do not conceal or pay this milestone before verification and photos if this work will become hidden.
Stop if
Stop if variations exceed what the product or method can accommodate.
Evidence to keep
Overall photo, close-up detail, product used and relevant measurement or test.

Execution
Preassemble, level and anchor
Most finishes follow substrate defects rather than hiding them.
Substeps
- Preassemble, level and anchor; load gradually and check deflection.
- Check with a straightedge, level or string lines suited to the project scale.
- Correct small areas and feather gradually into existing surfaces.
- Repeat measurements after compaction, drying or fastening.
- Dry-fit and confirm alignment, operation and access before permanent fastening.
- Photograph this point and record product, measurement or result before proceeding.
Homeowner role
A competent DIYer may perform this step only if the scope remains non-regulated, the substrate is sound and the exact instructions are understood.
Qualified role
Load-bearing wall, regulated service, hazardous material surface or specialized fabrication.
Quality check
Variations are within product tolerance and intended slopes direct water properly.
Hold point
Do not conceal or pay this milestone before verification and photos if this work will become hidden.
Stop if
Stop if correction would require structural changes or conceal an active cause.
Evidence to keep
Overall photo, close-up detail, product used and relevant measurement or test.
