Which of the following statements is true with regard to worksite safety inspections?
a.Unbiased inspections are best conducted by personnel who only have a generalist's knowledge of
the subject area being inspected.
b.The most useful findings come from scheduled inspections.
c.Inspections, by design, should always be generically oriented in nature.
d.Inspectors are independent entities who do not have a direct affiliation with the organization or
entity undergoing inspection. - ANSWER D
Effective worksite safety inspections are usually conducted by inspectors who are independent
entities that do not have a direct affiliation with the organization or entity being inspected and are
likewise typically conducted by personnel who have expert-level knowledge, training, and/or
experience within the subject area(s) being inspected. Furthermore, inspections can either be
unscheduled or scheduled, but unscheduled inspections typically provide better insights than
scheduled ones.
A robust incident reporting system typically includes which of the following facets?
a. Mechanisms for filing "lessons learned"
b. Remote electronic access capabilities in the field
c. Clear direction on how to differentiate and properly distinguish among incident severity categories
d. Established processes for commencing worker compensation claims - ANSWER C
A robust incident reporting system (IRS) typically includes reporting mechanisms for properly
differentiating and distinguishing between and among incident severity categories.
,Which of the following is a major advantage that is characteristic of undergoing an external versus
internal audit?
a. Benchmarking of audit findings against those of competitors
b.Higher levels of subsequent managerial engagement in response to findings
c.More rapid initiation of corrective actions in response to discovered findings
d.Direct national certification opportunities (e.g., International Organization for Standardization [ISO]
and ANSI) are more readily available via external audit corrective action measures - ANSWER D.
A major benefit that usually results from undergoing an external audit is the attainment of
benchmarking information (per audit findings) against that of industry competitors who have
undergone similar audits
Which of the following is often associated with frostbite of the fingers or toes?
a.Absence of pain
b.Fibromyalgia
c.Chilblains
d.Localized capillary damage to the hands and feet from high blood pressure - ANSWER 4.
A
Frostbite is a dangerous condition that can occur as a result of prolonged exposure to extreme cold.
It manifests when the temperature of body tissues falls below the freezingpoint of those tissues
(essentially below the freezing point of water). In such instances, tissue damage usually occurs and
can potentially lead to the loss of damaged toes or fingers in severe cases (digital frostbite). In
addition, the victim may or maynot feel pain associated with the onset of such a condition and
likewise may also encounter skin that turns gray or white in color. In contrast, chilblains are another
type of health hazard that can occur from overexposure to cold; however, these usually result from a
combined exposure to cold and humidity and are typically depicted by toe redness, inflammation,
itching, and occasional blistering.
Besides lead, which of the following is also typically utilized as a robust shielding material for
protection against gamma or X-ray radiation?
a.Aluminum
b.Water
,c.Lithium
d.Beryllium - ANSWER B
Light metals such as aluminum, lithium, and beryllium are typically not employed as effective
shielding materials for protection against exposure to gamma or X-ray radiation. The best shielding
materials against these types of ionizing radiations include lead, concrete, uranium, and water.
Which of the following is often a typical means by which hazards can arise during the conduct of
maintenance activities?'
a. Maintenance procedures are being followed in too literal of a fashion.
b. Manufacturer recommendations are regularly superseding internally driven mandates.
c. Maintenance schedules are not adhered to.
d. Over-allocation of resources is selected for maintenance items - ANSWER C:
Workplace hazards may arise in a number of different ways during the conduct of maintenance
activities, including not adhering to consistent maintenance schedules; utilizing incorrect or outdated
maintenance schedules; using poorly written maintenance procedures that do not clearly convey
necessary step-by-step protocols; and executing work functions on systems that are not of a user-
friendly design for maintenance (e.g., limited access or service locations).
The tangent of angle ∠ABC (note: drawing is notto scale) is equal to:
a.b/a
b.c/b
c.a/b
d.a/c - ANSWER A
The tangent of angle ∠ABC is by definition equal to b/a, which is the opposite side over the adjacent
side.
Which of the following is NOT a widely employed method used in industry for reducing hazardous
noise levels?
a. Using sound-absorbent materials in building construction
b. Decreasing vibrational frequencies
c. Employing white-noise background sources for dilution
d. Decreasing flow rates - ANSWER C
, Several methods can be deployed in the workplace for significantly reducing hazardous noise levels;
such strategies can include the use of double-barrier hearing personal protective equipment (PPE),
whereby both earplugs and earmuffs are worn byworkers, and installation of sound-absorbent
materials, decreasing vibrational frequencies and sound flow rates and redirecting sound sources
away from workers. Attempting to integrate white-noise (background) sources within a noisy work
environment can actually add to gross ambient noise levels and is thus not recommended
9. What type of glove material is widely used for protecting the hands against welding
sparks?a.Neoprene
b.Polyester
c.Leather
d.Polyethylene - ANSWER C
Gloves made from leather or cowhide material are conventionally used for effective protection
against welding sparks. Gloves made from other (synthetic) materials (e.g., neoprene or rubber) are
widely used for protection against chemical agents
What is the statistical medianof the following data set (6, 13, 15, 15, 18, 24, 28, 33, 51, and 66)?
a.26.9
b.18 and 24
c.21
d.36 - ANSWER C
The number 21 is the statistical medianof the data set: 6, 13, 15, 15, 18, 24, 28, 33, 51, and 66. If
there is an even number of values in a data set (such as 10 for this case), themedian is the average of
the two middle values of the set. Thus, (18+24)/2 = 21. If there were an odd number of values, the
median would be the value that has the same number of values that are both above and below it.
For instance, if the data set instead consisted of the following nine values—6, 13, 15, 15, 18, 24, 33,
51 and 66—the median would be 18 because it has four values that are greater and four values that
are lesser.
What is typically regarded as the MOST difficult challenge associated with the generation of a cost-
benefit analysis?
a.The performance of associated cost-benefit analysis risk assessments
b.Determining how much a human-life is "worth" from a financial perspective
c.Accurately determining potential long-term cost savings of a proposed safety enhancement
d.Substantiating design-basis criteria - ANSWER B
Determining how much monetary value to place on a human life is usually regarded as the most
difficult challenge associated with the rendering of a cost-benefit analysis. Other facets such as the
