8/8/2019 Abestos Abatement Decision

1/17

INTRODUCTION

A knowledge-Based System that aims at assisting the

project manager of Asbestos-testing and consulting firm

in deciding on an asbestos abatement recommendation for a

building in a light of existing strategic, legal and

social concerns. The system again helps in solving the

many demand for experts and constrains facing the

industry.

The system is based on five major factors;

1. Strategic and Operational Business

2. Condition of Asbestos

3. Type of Asbestos

4. Legal Factors

5. Degree of Social Pressure

The system is based on the following five key

factors; Strategic and Operational Business,

Condition of Asbestos, Type of Asbestos, Legal

Factors, Degree of Social Pressure.

Recommendations

The recommendations that the system make are:

Removal, Encapsulation, Enclosure, and No action

At this point, the recommendations to be included

in the prototype system are deliberately limited

to the following four:

Removal: Removal is the most widely

recommended abatement procedure.

Removal eliminates the asbestos source and the

need for special operations and maintenance

programs. It is also the most expensive

recommendation to carry out, in some cases

requiring a shutdown of facilities.

A removal recommendation is made if the strategic

and operational business considerations are long-

term, if the condition of the asbestosis poor, if

the type of asbestosis rated high or medium, if

the legal factors are high, and if the degree of

social pressure is high.

Encapsulation: Encapsulation involves coating

asbestos with a sealant that binds the asbestos

fibers together to create some resistance to

physical and mechanical damage. Encapsulation is

recommended if the strategicand operational

business considerations are short-term, if the

condition of the asbestosis fair or poor, if the

type of asbestosis rated medium, if the legal

factors are low, and if the degree of social

pressure is low.


16/17

Enclosure: Enclosure involves constructing

airtight walls and ceilings around the asbestos-

containing material. This reduces exposure in the

area outside the enclosure. Initial costs of

enclosure are lower than those associated with

encapsulation or removal; but long-term costs can

be higher, since enclosure does not eliminate or

alter the condition of the source of asbestos.

Enclosure is recommended if the strategic and

operational business considerations are short-

term, if the condition of the asbestos is fair,

if the type of asbestosis rated low, if the legal


pressure is low.

No action: The recommendation to take no

action may be made when the asbestos-containing

material is in good condition and has no chance

of being disturbed. If abatement action were

taken in such a situation, it might cause a more

hazardous condition than previously existed.

Periodic inspections to ensure the integrity and

soundness of the asbestos containing material in

question remain necessary when this

recommendation is adopted. No action is

recommended if the strategic and operational

business considerations are short-term or long-

term, if the condition of the asbestosis good, if

the type of asbestosis rated low, if the legal

pressure is low.
