Renovation is occupational dust exposure visited on households: silica from cutting, plaster-and-drywall fines, old-house surprises — at concentrations weekend enthusiasm rarely respects.

The home-project protection standard.

Key Takeaways

  • Silica cutting is occupational-disease territory — control it like one.
  • Sheet-and-zip containment protects the whole house cheaply.
  • Capture at the tool beats every downstream measure.
  • Pre-1980s materials: test before disturbing — the one absolute.

The Dust Problem Set

The hazard roster: SILICA (concrete-tile-stone cutting's crystalline dust — the occupational-disease class demanding real controls), DRYWALL-and-plaster fines (the everything-coating nuisance with gypsum's irritant edge), WOOD dusts (sensitising species included), and OLD-HOUSE surprises — pre-ban materials where ASBESTOS-and-LEAD protocols override everything (pre-1980s-class renovations test-first; disturbance without survey is the chapter's one absolute stop). Dose scales with power tools: cutting-and-sanding aerosolise what hand-work merely chips.

Containment Protocols

The site-control layer: PLASTIC-SHEETING zones with zipped doorways (the containment the pros bill for — tape-and-sheet economics protecting the whole house), NEGATIVE-PRESSURE where serious (window fan exhausting the work zone — flow INTO the mess), HVAC isolation (registers sealed, systems off during dusty phases — ducts distribute what they ingest per the duct chapter's construction-debris case), and TOOL-side capture (shrouded grinders, vacuum-attached sanders, wet-cutting methods — the source control that out-performs every downstream measure).

PPE That Works

The personal layer: FFP2/N95-class FITTED respirators as the floor (silica-and-serious work escalating to FFP3/P100 — the fit-and-class rules of the occupational chapter at home), eye protection against the irritant fraction, and the clothing-boundary habit (work clothes OFF at the zone's edge — dust commutes on fabric). Household-protection corollary: sensitive members (asthma, pregnancy, infants) relocated for the dustiest phases.

Post-Project Cleanup

The closure protocol: settle-time before teardown (hours, not minutes), HEPA-vacuum everything before any dry sweeping (brooms re-launch the project), damp-wipe sequencing walls-to-floors, filter changes post-project (HVAC filters loaded by renovations retire), and the containment coming down LAST. The air clears when the cleanup method says so, not when the eye does.

Renovation verdict: contain the zone, capture at the tool, fit the respirator — and let pre-1980s houses be tested before touched.

Frequently Asked Questions

Is DIY renovation dust actually dangerous?

Dose-dependent and real: silica-and-fine dusts at power-tool concentrations warrant genuine controls — containment, capture, fitted respirators — not bandanna optimism.

What mask do I need for sanding and cutting?

Fitted FFP2/N95 as the floor; FFP3/P100-class for silica-heavy cutting-and-grinding. The seal and the class together make the protection.

How do I clean up renovation dust properly?

HEPA-vacuum first (never dry-sweep), then damp-wipe top-down, change HVAC filters after, and drop containment last — the sequence prevents re-launch.
