Safety Engineering Midterm Question
and answers verified to pass 2025
1. What means has society used to reduce safety and health risks resulting
from technological advances? - correct answer ✔Society has responded to
the safety and health risks placed on them by technology, primarily through
regulation and litigation.
What is the one common reason for state engineering registration laws? -
correct answer ✔The one justification for engineering registration laws is
"protecting public health, safety, and welfare." This concept assumes that
those who appropriate education and experience and are able to sit for and
pass an examination are qualified to provide the protection expected by the
public. Engineers must also work with other professionals to achieve and fulfill
challenges given by those laws for the protection of society.
What is the one reason used to justify state laws that establish registration for
engineers? - correct answer ✔All states have laws governing the registration
or licensing of certain professionals, such as engineers, architects, lawyers,
and physicians. The one justification found in each of these laws is protection
of the safety, health, and welfare of the public.
What are the three major reasons for safety? - correct answer ✔·
Humanitarianism- moral basis for safety
· The law- minimizes differences in standards for right and wrong; formalizes
standards
· Cost- determines the actual value of property, human capabilities, and life.
Measured in avoidance of expenditures/the values of lost abilities and
property
, What is Heinrich's 4:1 ratio? What is important about it? What are its
limitations? - correct answer ✔· The 4:1 ratio says that the total cost
associated with accidents is much higher than the direct expenses.
· Indirect costs are the major expenses related to incidents, but they are
difficult to assess.
· The limitation is that the ratio varies for different companies and different
types of operations.
1. What is Heinrich's 300 :29 : 1 ratio? What is important about it? What are its
limitations? - correct answer ✔· Heinrich's 300:29:1 ratio says with 330
accidents, 300 will result in no injuries, 29 will result in minor injuries, and 1
will result in major lost, time injury.
· This ratio is a concept that says preventative actions should focus on
accidents and their causes, such as, unsafe acts and unsafe conditions.
There are many opportunities to implement these actions before minor or
major injuries occur.
· The limitation is that it only accounts for injuries and nothing else. In another
study, Bird and Germain included prevention of damage-causing accidents.
Distinguish between hazard and risk. - correct answer ✔· Risk is a measure
of both the likelihood and the consequences of all hazards of an activity or
condition. It is a subjective evaluation of relative failure potential. It is the
chance of injury, damage, or loss.
· A hazard is the potential for an activity, condition, circumstance, or changing
conditions, or circumstances to produce harmful effects. A hazard is an
unsafe condition.
What is the energy theory? Identify at least 5 strategies for incident prevention
based on the energy theory. - correct answer ✔Energy theory is a theory that
suggests that quantities of energy, means of energy transfer, and rates of
transfer are related to the kind and severity of injuries.
· Prevent the marshaling of energy
