Conducting site inspections.
(1)
Walk-through survey. A thorough walk-through survey should be made of
each building. Each building manager should be contacted beforehand to arrange for access into
locked spaces. The inspection normally begins in the boiler room and expands to include other
functional spaces in the same building. Lagged vertical riser pipes commonly run through
closets, storerooms, or other out-of-the-way places. If it is known that the building is to be
demolished, it would be prudent, whenever practicable, to break into chases, or walls and
ceilings to determine whether ACM is present. Crawl spaces and attics should be checked
carefully. For structures built upon a concrete slab, asbestos lagged pipe may be present in
below-slab trenches. Building maintenance personnel are often a valuable source of information
regarding the details of construction and the locations where ACM may be present. It is
important to remember that if a situation is discovered that is immediately dangerous to life or
health, the inspector should immediately notify the Safety Office.
(2)
Collection of bulk samples. Collecting a sufficient number of
representative samples of the various types of ACM is a vital part of the survey. These bulk
samples should be carefully selected from each type of suspect construction material from
locations throughout the functional space. In the case of pipe lagging, for example, the idea is to
distribute the bulk sample variants so as to include all variants of pipe lagging having different
physical appearances (e.g., changes in an outside diameter (OD), covering material, hardness, or
color). Additional information on bulk sampling and analysis are contained in chapter 8.

Army Asbestos-Containing Material Assessment Checklist
a.
The Army ACM Checklist in appendix C is divided into two parts.
(1)
Part I addresses the extent of existing damage and the potential risk of
damage to friable ACM.
(2)
Part II addresses exposure potential and associated factors that contribute
to health hazards in the occupied functional space being evaluated.
b.
Evaluating the extent of damage to the ACM or the potential for damage is an
important part of the assessment. This is because, in most cases, damaged ACM will release
more airborne asbestos fibers than undamaged ACM under identical conditions. Also, the more
extensive the damage, the greater the potential for fiber release.
c.
Assessment factors, such as physical damage, water damage, asbestos content,
and the attendant value-weighted conditions, in Part I is self-explanatory. Other assessment
factors, in Part I and II however, have additional considerations that could influence the
evaluator's choice of a value-weighted condition. The remainder of this section deals with some
additional considerations.
