Biosafety levels are used in Risk Management, true or false
True
52
A microorganism that is unlikely to cause human or animal
disease.
Risk Group 1 (no or low individual and community risk)
53
A pathogen that can cause human or animal disease but is
unlikely to be a serious hazard to laboratory workers, the
community, livestock or the environment. Laboratory exposures
may cause serious infection, but effective treatment and
preventive measures are available and the risk of spread of
infection is limited.
Risk Group 2 (moderate individual risk, low community risk)
54
A pathogen that usually causes serious human or animal disease
but does not ordinarily spread from one infected individual to
another. Effective treatment and preventive measures are
available.
Risk Group 3 (high individual risk, low community risk)
55
A pathogen that usually causes serious human or animal disease
and that can be readily transmitted from one individual to another,
directly or indirectly. Effective treatment and preventive measures
are not usually available.
Risk Group 4 (high individual and community risk)
56
Infectivity is indirectly proportional to biosafety measures. true or false
false it should be direct
57
Host range, Dissemination in the community, Infectivity, and Effectiveness of prophylactic measures are all indirectly proportional to biosafety measures. true or false
False, only the Effectiveness of prophylactic measures is indirect
58
The greater the severity, the higher the biosafety levels or
precautions to undertake.. true or false
true
59
RISK GROUPS are based on
Pathogenicity, MOT, effective preventative measures, and effective treatment

→ Action
→ Interrogate
74
Process of identifying the hazards/threats and evaluating the risks
associated with biological agents and toxins, taking into account the
adequacy if any existing controls, and deciding whether or not the risks are acceptable
assessment
75
The actual process of determining the likelihood (probability) and
consequence (severity) of a particular risk within a Risk Assessment
Risk Characterization
76
A crucial intermediary step between Risk Characterization and taking
active steps toward mitigating risk
* It is the process of determining, subjectively, whether a risk is high or low,
and whether it is acceptable or not
Risk Evaluation
77
Measures of control that will help you to lessen the risk that has been
assessed
mitigation
78
The most effective way to mitigate risks rely on the combination of the
measures and observance of proper utilization.
Personal Protective Equipment
79
there is no systematic way for evaluating risk and
determining risk acceptability. This will depend on the perceptions of
individuals, institutions, and the community. true or false
true

Hierarchy of Biorisk
bottom to top
Inadequate biorisk management - Near miis - harmful incidents
