CSST Exam
Why was asbestos added to construction materials ?
It provided: insulation properties, strength and durability from weathering, made spray on products
easier to apply, and does not conduct electricity.
What are the three types of asbestos and their associated species?
Chrysotile : Serpentine , Amosite and Crocidolites : amphiboles.
What is the predominant color and structure of Chrysotile asbestos?
white , long , curly , hollow
What is the predominant color and structure of Amosite asbestos ?
brown / tan ; long and straight
What is the predominant color and structure of Crocidolite?
blue ; long and straight
,What is the definition of a Surfacing material ?
A sprayed on troweled on or otherwise applied to structural surfaces EX: acoustic / decorative ceilings,
fire proofing, textured paints and plasters.
what is the definition of Thermal Systems Insulation?
applied to pipes, fittings, tanks, other structural, components etc. , to prevent heat loss or gain. EX: pipe
insulation, elbow mud, block insulation, air cell, asbestos paper wrap, preformed halves, magnesium
silica, etc
what is the definition of Miscellaneous products:
material that is not TSI or surfacing but applied to structural components.
Define Friable vs non friable.
Friable asbestos will crumble , pulverize or otherwise release dust by applying hand pressure.
What agency does not use the term friable ? why?
OSHA - because tools that are used by workers can easily make non friable materials friable
Primary type of asbestos used in the U.S ?
Chrysotile.
,List three building materials / locations where ACM is likely to be found
fire doors, fume hoods, felt under roofs or siding, amosite sheeting, kiln bricks and cement, lab
equipment, fire safety and equipment, auditorium curtains, gaskets, vibration joints, etc.
What are the 3 major illnesses related to asbestos exposures ?
Asbestosis, Lung Cancer, Mesothelioma
What is a latency period ? What is the latency period for asbestos related illnesses ?
the time between exposure and symptoms / sign of illness. 10-40 years.
Why does cigarette smoking increase chances of getting an asbestos related illness ?
Paralyzes Cillia in lung.
What asbestos related disease normally appears only after long, large, occupational exposure to
asbestos ?
Asbestosis
, what asbestos related disease primarily affects those exposed to asbestos who smoke cigarettes?
lung cancer - increases chances over 50 times.
who must participate in a medical surveillance program
-Employees who conduct Class I, Class II, and Class III work for more than thirty days.
-Employees who are exposed over the PEL for thirty or more days in a year.
When are asbestos medical surveillance physical exams required ?
- Before doing the work (pre employment, pre placement)
- Annually
- Upon termination (Cal OSHA requirement)
What should be performed at an asbestos medical surveillance exam ?
Occupational History Exam, Chest X ray, Pulmonary Function Test, stool sample
Is there a safe level of asbestos exposure?
no
