expected loss over a period of 12 years?
A)
$180,000
B.)
$270,000
C.)
$250,000
D.)
$360,000 Right Ans - D
Which of the following best meets the definition of"Highly Toxic" as described
in the OSHA Hazcom standard?
A.) A chemical that causes visible destruction of, or irreversible alterations in,
living tissue by chemical action at the site of contact
B.) A chemical that has a median lethal dose LD 50 of 50 milligrams or less per
kilogram of body weight when administered orally to albino rats weighing
between 200 and 300 grams each
C.) A chemical that causes a substantial proportion of exposed people or
animals to develop an allergic reaction in normal tissue after repeated
exposure to the cheiiiical
D.)A chemical that has a median lethal dose LD 50 of more than 50 milligrams
per kilogram but not more than 500 milligrams per kilogram of body weight
when administered orally to albino rats weighing between Right Ans - B
Medical records maintained under the provisions of 1910.1030 must be
retained for what period of time?
A.) 30 years
B.) Duration of employment plus 30 years C.) 5 years
D.)Duration of employment plus 5 years Right Ans - B
Wlllch of the following precautions would be the least effective against
occupational dermatoses?
A.) Frequent washing of the face and hands with an organic solvent followed
by soap and water
B) Use of good housekeeping and frequent washing with soap and water
Good hygiene practices and use of gloves
D.)Frequent washing with soap and water and the use of barrier cream.
Right Ans - A
,Which of the following techniques would be the preferred control method for
preventing exposure to a hazardous noise exposure?
A.) Control employee work hours to reduce exposure time B.) Engineer a less
hazardous environment
C.) Provide protective equipment
D.)Automate the process to reduce worker interaction Right Ans - B
Which of the following concerning dilution ventilation is correct? Dilution
ventilation is used to:
A.) Control a contaminant at its source B.) Control fumes from lead fusing C.)
Control low toxicity vapors
D.)Control asbestos fibers Right Ans - We selected answer C because:
Dilution ventilation lowers the concentration of a contaminant by adding air
to the general work area. Since the air is added to the general work area it will
not effectively control exposure to a toxic or highly toxic substance used in a
specific location.
Which of the following best describes the audiogram?
A.) A ear-cleaning machine
B.) A hearing booth and noise measuring instrument C.) A indicator of hearing
acuity
D.) A tool to detect high hazard noise areas Right Ans - We selected answer
C because:
An audiogram is a record of hearing loss or hearing level measured at several
different frequencies, normally from 500 to 6000 hertz. Hearing levels are
generally presented graphically as a function of frequency. The audiogram
measures the acuity or sharpness of hearing ability.
When respirator qualitative fit testing, required by OSHA, is conducted, which
of the following is used to perform taste threshold screening?
A.) Isoamyl Acetate B.) Isopentyl Acetate C.) Banana Oil
D.)Sodium Saccharin Right Ans - We selected answer D because:
Taste threshold screening is conducted using a solution of 0.83 grams of
sodium saccharin in water. Safety and Health Practitioners preparing for the
CHST examination should become familiar with all of the Qualitative Fit Test
Protocols required by OSHA.
, Which of the following would not be required in an OSHA mandated hearing
conservation program?
A.) Workers must be provided with hearing protection B.) Workers must be
trained and retrained annually C.) Given an audiogram within 6 months
D.) Workers must be given time off to protect hearing Right Ans - We
selected answer D because:
The OSHA requirements include provisions for insuring that the employees
are provided hearing protection, given a baseline hearing test (audiogram) in
most cases the audiogram is required within 6 months.
However requirements for removal from the industrial environment to
protect hearing is required only after a hearing threshold shift is detected.
Which of the following is not a principle benefit of a Job Safety Analysis (JSA)?
A.) Assist the supervisor in training
B.) Tool to study jobs for possible improvement C.) Instruct new personnel on
a specific job
D.)Replaces workplace procedures Right Ans - We selected answer D
because:
The principle benefits of a Job Safety Analysis (JSA) are:
Allowing the supervisor to perform training for safe, efficient operations
Allowing the supervisor or other person developing the JSA to meet and work
with employees
Instruction of new employees on specific jobs
» Instruction of current employees on the specifics ofjobs performed
irregularly
As an accident investigation tool should a mishap occur
Studying jobs to determine if improvement is possible
Which of the following is stool correct concerning the safety afforded by
building codes?
A.) Building codes ensure safety of all concerned B.) Building codes should be
considered paramount C.) Codes protect construction workers
D,) Codes represent the minimum requirements for materials and
construction Right Ans - We selected answer D because:
Building codes are designed to protect the future occupants of the building
and offer little protection for the actual construction workers. Because codes
attempt to predict the future use of the building they are considered the
absolute minimum protection requirements.
Arrange the following hazard control steps in the proper sequence: (1) guard
the hazard (2) engineer the hazard out if possible (3) educate personnel.
A.)
2,1,3
B.)
3,1,2
C.)
1,2,3
D.)
3,2,1 Right Ans - A
