STEP ONE: Assessment and Survey
The first step of the Asbestos Management Program is to do an asbestos survey to
assess the location, identify the type of asbestos, the condition of the asbestos and
identify a maintenance record. This asbestos inventory or assessment is usually carried
out by an independent consulting firm. This assessment or survey will include:
1. Identification and location of
the Asbestos Containing Materials (ACM)
2. Assessing the condition of asbestos and its accessibility.
3. Preparing a long term plan to outline the corrective action(s) to
be taken and the immediate and long-term costs associated with the corrective action(s).
STEP TWO: Notification
Once the assessment or survey is completed, this will allow the building
manager to implement the second step of the program, which includes notifying tenants,
custodial and maintenance staff, building maintenance and service contractors. This
notification includes identifying the location of the asbestos containing materials.
STEP THREE: Worker Training
A Health and Safety Training
Program should be established including an inspection policy and employee training
program. Employees who are most likely to come into contact or work with asbestos should
be included. Good communication is vital. All sub trades
and maintenance contractors should
STEP FOUR: Corrective Measures - Correction and
Where the survey or assessment has identified
Asbestos Containing Materials (ACM) which are severely damaged or deteriorated, the
building manager then decides which of the following three methods of corrective or
remedial measures are going to be used.
1. Removal By Type 1, Type 2, or Type 3 Operational Procedures
As a rule, removal will initially be the most expensive method. However, depending
on the circumstances, in the long run, asbestos removal can be an economically preferred
option. Removal of asbestos is the only permanent solution.
most cases, where Asbestos Containing Materials (ACM) are removed, an appropriate
substitute material must be reinstalled. Fibreglass pipe covering is a widely used product
and the costs associated with supplying and installing this new material are relatively
Type 3 Operational Procedures, an eight chamber Decontamination Structure is installed. A
Dirty Area Room, Garbage Storage Area and Clean Area & Room with airlocks are
temporarily installed. These Decon's have filtered showering facilities. The water is
filtered through a .05 micron filter collected into 45-55 gallon drums for testing prior
to any discharge.
Type 3, the area is kept constantly under negative pressure. HEPA Filtered Negative Air
Pressure Units are installed strategically and vented outside. All electrical equipment,
HEPA Vacuums, temporary lighting and Negative HEPA Air Units are hooked up to temporary
Ground Fault Interrupt (GFI) panels. The area will have electrical lockouts where
Encapsulation is a successful option in dealing with asbestos and involves
covering the asbestos with a sealant.
Containing Materials (ACM), all piping, elbows, boilers and all mechanical insulation
covered with ACM and asbestos are HEPA vacuumed and covered with a canvas fire-rated
adhesive sealant (encapsulation). Depending on the application, there are a number of
types of sealant.
sealant's function is to enclose and prevent the asbestos fibres from breaking away from
the material. In the case of asbestos pipe insulation, elbows or trees, a canvas with a
fire retardant lockdown adhesive lagging is applied to cover and provide a
requires periodic inspections, quarterly or annually, to monitor the condition of the
Asbestos Containing Materials.
The Enclosure method permanently closes the asbestos. The enclosure must
be completely airtight and this method is best used only where access to electrical,
plumbing or ventilation services are not required.
