The drawing to the left is a cut away view of a typical modern
construction house in the USA. It show a view of a wall and floor as it
would be seen if the wall and floor were simply cut off someplace in the
middle of a wall.
The point is to show the many layers and components involved in
building a wall and floor section. It also shows all the places where
liquid contamination can hide once it gets near the edge of the
flooring or carpet.
The hole drilled diagonally from the left is sometimes necessary to
inject OdorXit solution into the area between the plate at the bottom of
the wall and the subflooring. Drilling small holes through the hardwood
flooring is sometimes necessary to inject OdorXit to areas that took
urine weeks to get contaminate.
This is what a minimum quality respirator looks like. This one is
available from Sears for less than $15 and it could save your life on a
nasty, dusty rehab project.
When cleaning, sweeping, sanding, removing plaster, drywall, base
boards, door molding, carpeting and other contaminated or dusty
components, the stuff sturred up and floating in the air often contains
large quantities of mold, asbestos, lead, powdered feces, and who know
what other nasty things. This close fitting respirator may be hot to wear,
but it will filter out most of the stuff that can make you permanently
sick. Don't take chances with your health, use a respirator.
