LABORATORY BIOSAFETY - Answers IT IS PROTECTION FOR WORKERS
LABORATORY BIOSECURITY - Answers PROTECTION FOR MICROORGANISM OR PATHOGENS
LABORATORY BIOSAFETY - Answers are containment principles, technologies, and practices
implemented to prevent unintentional exposure to pathogens and toxins, or their unintentional release
BIOSECURITY - Answers are protection, control and accountability for valuable biological materials
within laboratories, in order to prevent their unauthorized access, loss, theft, misuse, diversion or
intentional release
RISK GROUP 1 - Answers Unlikely to cause harm or disease on healthy individuals
RISK GROUP 2 - Answers •Can cause disease but moderate or less serious hazard
•Preventive measures and medications available
RISK GROUP 3 - Answers •Can cause serious disease but not ordinarily spread
•Preventive measures and medications available
RISK GROUP 4 - Answers •NO MEDICATIONS, causes serious disease and easy mode of transmission
Pathogenicity of the organism
Mode of transmission, host range, immunity, vectors and environment
Local availability of preventive measures
Local availability of effective treatment - Answers Classification of risk groups may vary from one country
to another depending on:
Biosafety Level 1 - Answers suitable for work involving not known to cause disease; minimal potential
hazard to laboratory personnel
Biosafety Level 2 - Answers similar to Level 1; moderate potential hazard
Biosafety Level 3 - Answers done with indigenous or exotic agents which may cause serious or
potentially lethal disease after inhalation
Biosafety Level 4 - Answers work with dangerous and exotic agents that pose a high risk of aerosol-
transmitted laboratory infections; may cause severe to fatal disease in humans, vaccines or other
treatments are not available
HIGH EFFICIENCY PARTICULATE AIR FILTERS - Answers DEFINITION OF HEPA FILTER
HEPA FILTER - Answers Remove particles,including microorganisms, from the air
, Biological safety cabinet - Answers it use hepa filter to treat air --inflow / exhaust
class 1 , 2, 3 - Answers 3 types of biological safety cabinet
Class I - Answers provide worker and environmental protection, but no product protection. exhaust air
filtered
Class II - Answers filter both exhaust and intake air to protect the worker and the environment from the
contamination as well as to protect product in the cabinet. suitable for micoorganisms assigned to bio-
safety level 1, 2, 3..
Class III - Answers gas tight provides the highest attainable level of protection to personnel and the
environment.
