Here are the recommended steps for properly cleaning up after working with ceramic fiber thermal insulation board:
Contain work area
Completely seal the work area with plastic sheeting on floors, walls and any surfaces.
Mist during cutting
Use an encapsulant spray to mist surfaces as you cut or shape the board to bind loose fibers.
Wipe surfaces
Use wet rags or paper towels to wipe down all surfaces and tools within the containment area, picking up any loose fibers or dust.
Remove excess boards/scrap
Carefully place cutoffs or scraps into sealed bags, misting if needed.
Remove protection
After wiping, roll up used plastic sheeting from the inside out to avoid releasing fibers. Seal in bags.
Wash exposed areas
Wash your exposed skin (arms, face) before removing protective clothing to remove any fibers.
Remove PPE
Take off disposable coveralls, gloves, respirator last and seal in bags with the trash.
Wet clean floor
Mop floors thoroughly within containment area to pickup settled fibers.
Seal waste
Tightly seal all bags containing used rags, plastic, tools and PPE for safe disposal.
Ventilate
Ensure negative air pressure and allow the area to fully dry before re-entry without PPE.
Proper cleanup prevents exposure to loose ceramic fibers after insulation work is complete.
