BIOSAFETY Flashcards
These are measures employed when handling biohazardous materials
to avoid infecting oneself, others or the environment

“PROTECTING PEOPLE FROM BAD BUGS”
BIOSAFETY
How is biosafety implemented
The containment principles, technologies and practices that are implemented to prevent unintentional exposure to pathogens and toxins or their accidental release (WHO, 2006)
These are measures employed to protect biohazardous materials, or critical relevant information, against theft or diversion by those who tend to pursue intentional misuse
BIOSECURITY
How is biosecurity implemented
The protection, control and accountability for valuable
biological materials within laboratories in order to prevent unauthorized
access, loss, theft, misuse, diversion or
intentional release (WHO, 2006)
• risk associated to biological toxins or infectious agents
BIORISK
a system or process to control safety and security risks associated with the handling or storage and disposal
of biological agents and toxins in
laboratories and facilities (CWA 15793:2011)
BIORISK MANAGEMENT
• The International Standard for any organization that tests, stores, transports, works with, or disposes of hazardous biological materials
ISO 35001:2019
The biorisk management system
is based on a________ approach, which enables an organization to effectively identify, assess, control, and evaluate the biosafety and biosecurity risks inherent in its activities
management system
The model is an iterative process used by organizations to achieve continual improvement of processes and products.
PDCA
• : establish objectives, programs, and
processes necessary to deliver results in accordance with the organization’s biorisk management policy;
• : implement the processes as planned;
• : monitor and measure activities and
processes about the biorisk management policy and objectives, and report the results;
• : take actions to continually improve the biorisk management performance to achieve the intended outcomes.
Plan
Do
Check
Act
• The intentional release or threat of release of biologic agents (viruses, bacteria, fungi or their toxins) in order to cause disease or death among human population or food crops and livestock to terrorize a civilian population or manipulate the government (CDC)
BIOTERRORISM
may be the first to identify an unusual organism or cluster of isolates that may signal a bioterrorism event

Biosafety Levels
RITM
Microbes are dangerous and exotic, posing a high risk of aerosol-transmitted infections, which are frequently fatal without treatment or vaccines.
Few labs are at this level.
BSL 4
Biosafety Levels
Microbes are indigenous or exotic and cause serious of potentially lethal diseases through respiratory transmission.
BSL 3
Biosafety Levels
Microbes are typically indigenous and are associated with diseases of varying severity.
They pose moderate risk to workers and the environment.
BSL 2
Biosafety Levels
Microbes are not known to cause disease in healthy hosts and pose minimal risk to workers and the environment.
BSL 1
Biosafety Levels
Ebola and Marburg viruses
4
Biosafety Levels
M. tuberculosis
BSL 3
Biosafety Levels
SAU
BSL 2
Biosafety Levels
E. coli
BSL 1
Easily disseminated and/or transmitted from person to person
Can result in high mortality rates with a major public health impact
Might cause public panic
Category A
Moderately easy to disseminate
Moderate morbidity and low mortality
May require enhanced
CDC diagnostic capacity
Category B
Availability
Ease of production and dissemination
Potential for high morbidity and mortality
Category C
