Respiratory protection

Select for the hazard, never by appearance

Full mask guide

Possible hazards

  • task-specific dust or products to confirm
hazard assessment first

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

  • Choosing a respirator by appearance or colour is not a selection method.

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

Pool, spa and basin

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.

Understand the system

Layers and interfaces to watch

  1. 1

    Layout, barriers and secure access

  2. 2

    Base, structure and drainage

  3. 3

    Circulation, filtration and water treatment

  4. 4

    Electrical, bonding and heating as required

  5. 5

    Commissioning, cover and maintenance

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.
  • Excavation, structure, electrical, equipotential bonding, gas, heating and permanent connections.

  5. Coordinate structure, hydraulics, barriers and electrical safety before backfill or filling.
  6. 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

Excavation, structure, electrical, equipotential bonding, gas, heating and permanent connections.

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

Verify zoning, permits, setbacks, barriers, electrical, gas, plumbing and insurance

A check before putting tools away allows small defects to be corrected.

Substeps

  1. Verify zoning, permits, setbacks, barriers, electrical, gas, plumbing and insurance.
  2. Inspect from several angles and lighting conditions, then gently test stability or operation.
  3. Photograph hidden areas, products, lot numbers and useful measurements.
  4. Clean up, remove protection at the proper time and record required maintenance.
  5. Coordinate structure, hydraulics, barriers and electrical safety before backfill or filling.
  6. Photograph this point and record product, measurement or result before proceeding.
