Respiratory protection

Select for the hazard, never by appearance

Full mask guide

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.

Yellow phase — complex project

Framing, decks and assembled structures

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.

Homeowner can always

  • Measure, photograph, inventory and document existing conditions.
  • Compare products, unit prices, quantities, rentals and delivery or disposal charges.
  • Verify permits, licences, insurance, references and schedule before signing.
  • Protect belongings, prepare access and keep a daily work log.
  • Observe inspection points without modifying or commissioning a regulated system.

Competent DIY if allowed

  • Perform only non-regulated tasks you understand and that the local authority permits homeowners to do.
  • Follow manufacturer sequence, products and limits without improvising substitutions.
  • Complete a limited test before treating the entire surface or system.
  • Stop before concealing any interface that has not been photographed, tested or inspected.

Qualified trade, permit or inspection

  • Structural design, load sizing and modification of load-bearing elements.
  • Electrical, gas, combustion, refrigerant or regulated connections where required.
  • Permitted or inspected work reserved by the jurisdiction for a contractor or qualified trade.
  • Assessment and remediation of hazardous materials, extensive contamination or structural damage.
  • Foundations, house attachment, guards, stairs, beams, spans or loads requiring design or permit.
Before starting

Questions for the contractor

  1. What exact method do you propose for “Install or replace deck boards” and why does it suit existing conditions?
  2. Which products, models, thicknesses, quantities and accessories are included?
  3. Who obtains permits, schedules inspections and provides reports?
  4. Which concealed conditions would trigger a change and how will it be priced?
  5. Which work will be concealed and when can I photograph or inspect it?
  6. Which tests and measurements will be delivered at acceptance?
  7. Which exclusions, allowances, mobilization, delivery and disposal charges are not in the price?
  8. What labour warranty applies and who manages the manufacturer warranty?
  9. What is the milestone schedule and which delays are plausible?
  10. How will you protect the home, occupants and adjacent surfaces?

Milestone payments

  • Tie each payment to an observable milestone, not only a date.
  • Do not pay for concealed work before applicable photos, tests and inspections.
  • Retain a meaningful final amount until deficiencies are corrected and documents delivered.
  • Verify provincial rules governing deposits, holdbacks, liens and payments.

Change orders

  • No non-emergency change should begin without a written description of the cause and revised scope.
  • Price should separate labour, materials, equipment, schedule impact and credit for deleted work.
  • Request photos or evidence of the unforeseen condition before it is concealed.
  • Compare the minimum compliant option, recommended option and any optional upgrade.
  • Keep authorization, date and cumulative budget and schedule impact.
Final file

Documents to receive

  • Detailed invoices and proof of subcontractor payment where relevant.
  • Closed permits, inspection reports and test results.
  • Data sheets, warranties, serial numbers, colours, lots and spare materials.
  • Plans or photos identifying concealed elements, services and access points.
  • Operating, maintenance, winterization and inspection schedule.
  • Written list of corrected deficiencies and final acceptance date.
After the work

Maintenance and monitoring

  • Inspect the project after its first service season and after a major weather event.
  • Keep touch-up products, spare parts, lot numbers and documents.
  • Record any leak, crack, movement, noise, odour or performance change and act early.
  • Follow the manufacturer schedule for cleaning, filters, seals, protection or winterization.
  • Do not hide a recurring defect with sealant, paint or a temporary adjustment.
