AND ANSWERS SURE A+
✔✔Liabilities extend to the final user of the product, regardless of how many times it
changes hands. The liability extends to wholesalers, retailers, and to the final user and
is known as vertical privity. - ✔✔True
✔✔Quasi contracts - ✔✔one party would be enriched unjustly if permitted to enjoy
something received from another party.
✔✔Which of the following controls is the method of choice because of their ability to
isolate or eliminate hazards?
(Hint: a ventilation system is an example) - ✔✔Engineering controls
✔✔Where do industries set their regulatory limit for chemical exposures? - ✔✔In the
Doses Causing No Effect region, well below the NOAEL
✔✔Ergonomic stressors are human psychological and physiological injuries or illnesses
with repetitive and causative trauma, fatigue, and exertion. - ✔✔True
✔✔You walk into a facility and smell gasoline. What is the route of exposure? -
✔✔inhalation
, ✔✔Biological stressors include all of the following: ionizing radiation, non-ionizing
radiation, noise, and temperature - ✔✔False
✔✔Regarding the classification of toxic materials, which of the following is an example
of a physical form of toxic materials? - ✔✔Gases
✔✔Regarding the classification of toxic materials, which of the following is an example
of a chemical form of toxic materials? - ✔✔Alcohols
✔✔Regarding the classification of toxic materials, which of the following is an example
of a physiological classification? - ✔✔Mutagens (example: X-rays)
✔✔When two or more substances are taken into the body, what is an interaction that
may take place? - ✔✔All of the above
✔✔No matter which mode of entry a toxin takes, the health effects can either be local or
systemic. Systemic effects occur in the target sites of the body, which are not the initial
contact locations, but which, because of their affinity for that particular substance,
readily absorb it. - ✔✔True
✔✔When focusing on body position, which of the following is NOT a general guideline
for eliminating ergonomic factors? - ✔✔Keep arms outstreched whenever possible
✔✔Ergonomics is a multidisciplinary field that involves psychology, anthropology,
engineering, and chemistry - ✔✔True
✔✔Dynamics and statics are the two major biomechanical measurements - ✔✔True
✔✔Maintaining the position of a body part in order to hold something in place describes
what operational category of movement? - ✔✔Static movement
✔✔What is the physiological category of movement where the movement of a joint
decreases the angle between the bones? - ✔✔Flexion
✔✔What is tendinitis? - ✔✔The most frequently diagnosed CTD, results from
inflammation of tendons due to excessive use
✔✔What is the physiological category of the movement of a body part toward the center
plane of the body? - ✔✔Adduction
✔✔Operational classification systems examine the way body parts move - ✔✔False
