noise of an industrial motor vehicle is 80 dBA at a distance of 40 feet, what
is the sound pressure level at 10 feet?
• Question 2
What
are the substances called that are capable of damaging the liver, such as
carbon tetrachloride, chloroform, tannic acid, and trichloroethylene?
• Question 3
Asbestos
fibbers and silica dust may cause a what effect in the lung tissue?
• Question 4
Using
current Occupational Safety and Health Administration (OSHA) standards, if a
worker's noise exposure is 85% after five hours and 25 minutes of noise
exposure, and assuming conditions remain constant, what would the exposure be
after eight hours?
• Question 5
Which
of the following would be the hardest to remove during decontamination?
• Question 6
As a
general rule, power presses are best protected by fixed guards that enclose the
danger areas. When guards are not possible or practical, safeguarding devices
may be used to protect workers from point-of-operation hazards where moving
parts actually perform work on stock. Which type of safeguarding device
requires adjustment for each individual operator?
• Question 7
In
testing chemicals in the laboratory, toxicologists have learned that many
chemicals act together in certain ways on biological systems. When the exposure

doubling the dose of either one alone, such as isopropyl alcohol and
chloroform, what is this called?
• Question 8
What is
the term for chemicals or substances that cause damage or death to a developing
fetus, but the damage cannot be passed on to further generations, as it does
not affect the genetic code?
• Question 9
A
direct reading instrument indicates a concentration of 1.5% for hazardous
material that has a permissible exposure limit (PEL) of 150 ppm, an immediately
dangerous to life and health (IDLH) of 1500 ppm, and a lower explosive limit
(LEL) of 15,000 ppm. You have been assigned the task of respirator selection
for entry into this atmosphere. Which of the following statements is the most
correct?
• Question 10
A
__________ is a toxic agent or substance that inhibits, damages, or destroys
the cells and/or tissues of the kidneys.
• Question 11

disease. Some people have no problems or symptoms yet become carriers of the
virus. Which of the following represents the proper acronym for hepatitis B
