Medical Surveillance Program*
DESCRIBE the health hazards of asbestos. (Reference Navy Occupational Safety and
Health (NAVOSH) Program Manual for Forces Afloat, OPNAVINST 5100.19 Series
a. Characteristics of Asbestos
(1) Fibrous mineral which may contain iron, magnesium, calcium or sodium.
(2) Fireproof.
(3) Acid resistant.
(4) High Tensile Strength.
(5) Good heating and electrical insulation properties.
(6) Moderate/good chemical resistance.
(7) Flexible properties.
(8) Heat Resistant from 500 - 1500 degrees Celsius
b. Two types of asbestos containing materials.*
(1) Friable - can be crumbled, pulverized or reduced to powder by hand pressure.*
(a) Acoustic Insulation*
(b) Pipe Lagging*
(c) Sheet gasket material used in high temperature applications.*
(2) Non-friable - cannot be crumbled, pulverized or reduce to powder by hand pressure.*
(a) Brake and clutch linings*
(b) Floor tiles and adhesives*
(c) Gaskets**
c. Physical Conditions in which Asbestos Becomes a Health Hazard.
(1) Asbestos insulation or other asbestos-containing materials in good condition are generally not a health hazard when properly secured and unlikely to be disturbed.
(2) Bound asbestos materials, such as gaskets, floor coverings, and cements are not generally a health hazard unless work activities destroy their matrix.
(3) Specific work activities that disturb the make-up of asbestos materials:
(a) Punching
(b) Grinding
(c) Sanding
(d) Machining
(4) Normal deterioration - Asbestos fibers are released into the air. The loosely bound fibers are pulverized or easily crumbled creating microscopic contaminants that have been identified as a health hazard. (friable:))
LIST the diseases resulting from asbestos exposure. (Reference Navy Occupational
Safety and Health (NAVOSH) Program Manual for Forces Afloat, OPNAVINST
5100.19 Series).
