Environmental and Occupational Influences on Health Flashcards
define hazard
something with potential to cause harm
define risk
the likelihood of harm occurring
define risk factor
something which increases the risk of harm
define protective factor
something which decreases the risk of harm
define susceptibility
influences the likelihood that something will causeharm
give examples of types of hazards
Physical Chemical Mechanical Biological Psychosocial
give examples of routes of exposure
Skin
Blood/sexual
Inhalation
Ingestion
factors that influence the degree of risk include:
how much a person is exposed
how the person is exposed
conditions of exposure
what does risk combine?
the probability that a particular outcome will occur and the severity of the harm involved
what 3 principles govern the perception of risk?
Feeling in control
Size of the possible harm
Familiarity with the risk
how does feeling in control influence perception of risk?
Involuntary risks (situations where we believe we have little control) are perceived as having greater risk
Voluntary risks (situations we believe we have some control over) are perceived as less risk
how does the size of the possible harm influence the perception of risk?
Risks that involve greater possible harm are perceived as greater than those involving less harm
Even if the less harmful events are more likely
how does the familiarity with the risk influence the perception?
Risks that are less familiar are perceived as being greater than more familiar risks
individual variables in risk perception
Previous experience, attitudes towards risk, values, beliefs, Socio economic factors personality, demographic factors
the environment: direct pathological effects examples
Physical Ionising and non-ionising radiation Noise and Vibration Chemical Pesticides VOCs (volatile organic compounds) Biological Infectious agents Allergic substances
