MANAGEMENT OF OCCUPATIONAL
HEALTH AND SAFETY EXAM
QUESTIONS AND ANSWERS
Engineering control - Answer- Modification of work processes, equipment, and materials
to reduce exposure to hazards
Machine guarding - Answer- Protection for workers from the hazards and energies
created by moving machinery
Kickback - Answer- Action of having a work piece suddenly thrown backward into the
operator
Administrative - Answer- Management involvement, training of employees, rotation of
employees, environmental sampling, and medical surveillance to protect individuals
Preventive maintenance - Answer- The orderly, continuous, and scheduled protection
and repair of equipment and buildings
Confined space - Answer- Any space that is enclosed or partially enclosed and restricts
entrance and exit by the location and size, and is potentially deficient in oxygen or could
contain toxic gases
Physical agents - Answer- Sources of energy that may cause injury or disease
Ambient - Answer- All-encompassing conditions associated with a given environment,
being usually a composite of inputs from sources all around us
Early warning change - Answer- A deterioration of hearing in the upper frequency-the
earliest detectable sign on noise induced hearing loss
Vasoconstriction - Answer- Process of causing a constriction of the blood vessels
Hyperreflexia - Answer- The condition of unusually quick reaction by the nerves to some
external stimulus
Attenuated - Answer- Reduction of noise at one location compared to another farther
from the source
Segmental vibration - Answer- Vibrations that affect only parts of the body
Whole-boy vibration - Answer- Vibrations that affect the whole body as a unit
, Necrosis - Answer- Death of decay of tissue
Decalcification - Answer- Loss of lime salts (calcium) in the bones
Resonance - Answer- The effect that occurs when an object reacts strongly to some
particular frequency
Homeostasis - Answer- The balance of heat generation
Conduction - Answer- Heat transfer occurring when two surfaces are in contact
Convection - Answer- Heat transfer occurring when one surface adds heat to the
surroundings
Radiation - Answer- Heat transfer occurring when energy is transmitted by
electromagnetic waves
Biohazards - Answer- Hazards created by exposure to infectious microorganisms,
proteins, or nucleic acids
Chemical agents - Answer- Hazards created by exposure to chemicals
Agents - Answer- Any substances- chemical, biological, or physical- to which a human
may be exposed at work or at home
Chain of infection - Answer- The process and conditions by which biological agents are
spread from one host to another
Reservoir - Answer- The home or environment where the biological agent grows and
multiples
Portal of exit - Answer- The path by which a biohazards agent leaves its host
Mode of transmission - Answer- The means or channel by which an agent is carried
from one host to another
Portal of entry - Answer- The path by which a biohazards agent gains access to a new
host
Susceptible host - Answer- An individual or animal that becomes infected with a
biohazards agent
Toxicity - Answer- Ability to cause injury to human biological tissue
