Workshop ventilation: dust, fumes and solvents

Design source capture, make-up air, filtration and separation from the dwelling around actual activities.

VERT / GREEN

Inventory processes, products and contaminants before choosing a fan.

JAUNE / YELLOW

Welding, sanding, painting and wood dust do not have the same capture or filtration needs.

ROUGE / RED

Toxic fumes, flammable solvents, combustible dust or exhaust into the home: stop and have controls designed.

Interactive triage

This triage helps choose the next step; it does not replace design, permitting or professional diagnosis.

Welding/cutting
Provide local fume extraction and assess other process hazards. Frequent sanding/woodworking
Use source capture and dust control, not just a wall fan. Solvents/painting
Verify flammability, ventilation and suitable equipment before use. Occasional light work
Keep the area clean and prevent transfer into the dwelling.
