After we schedule a date to start the project, we must file a "Notification
of Abatement" with the State, postmarked no less than 10 days in advance
of the start of the project. On the day of the project, our technicians
will arrive between 8:00-8:30 AM, depending on traffic, distance from
our office, and other circumstances. All moveable objects will need to
have been removed from work areas prior to our arrival. We will also need
to have unobstructed, clear access to the work area.
After
our equipment and supplies are unloaded, we will proceed to set up the
decontamination chamber, which serves as the entrance and exit to the
actual work area. The decon allows workers to decontaminate the equipment
and themselves as they exit the work area. All critical barriers (windows,
doors, and other openings to the work area) will then be sealed with two
layers of thick plastic sheeting. �Asbestos Warning� signs
will then be posted at all project entrances. The Microtrap, a
sophisticated filtration device, will be set up either in the work area
or immediately adjacent to it. The microtrap filters out asbestos as well
as any other types of fibers that may be airborne before, or during the
abatement process. The purified air is exhausted outside of the work area,
at the same time creating a vacuum, which assures that the airflow is
always moving from outside the work area into the work area. This prevents
any fibers from escaping back into the living areas.
All
horizontal surface areas within the workspace will then be cleaned with
a Hepa Vacuum, which, like the Microtrap, filters out the smallest
of particles. The containment, which consists of two layers of thick
plastic which are placed on all walls and floors, will then be constructed.
All plastic seams are then sealed with duct tape. When the containment
is completed, the microtrap's negative pressure is checked and then actual
asbestos removal begins. All Asbestos material is wetted down with amended
water, which helps to minimize the chance that asbestos fibers will become
airborne.
The Asbestos is placed into 6mil thick asbestos bags, double bagged,
sealed, labeled, and then removed from the work area. All abated
surfaces along with the plastic containment and equipment are then
cleaned. A special "lock down" is applied, which secures any fibers
that may remain on the plastic. When completed, the area will be
ready for the final inspection and clearance for reoccupancy. The
independent, State Licensed, and Certified hygienist will inspect
the project and sample the air, which is then analyzed under a microscope.
Upon clearance, a �Certification of Clean Air/Clearance for Re-Occupancy�
Certificate is issued by the Hygienist, all plastic is removed and
the area undergoes a final cleaning.
