Lab Risks Flashcards
Safety sign symbols: what does it mean when the geometric shape is a red circle with a diagonal bar?
Prohibition
Safety sign symbols: what does it mean when the geometric shape is a blue circle?
Mandatory action
Safety sign symbols: what does it mean when the geometric shape is a yellow equilateral triangle with radiused outer corners?
Warning
Safety sign symbols: what does it mean when the geometric shape is green square
Safe condition
Safety sign symbols: what does it mean when the geometric shape is a red square
Fire equipment
What does PPE stand for?
Personal Protective Equipment
What is donning?
Putting on PPE
What is doffing?
Taking off PPE
Rearrange this in the correct donning procedure:
a. Lab gown/coat
b. 1st layer of gloves
c. 2nd layer of gloves
d. Face mask
e. Safety glasses
b, a, d, e, c
Rearrange this in the correct donning procedure:
a. Lab gown/coat
b. 1st layer of gloves
c. 2nd layer of gloves
d. Face mask
e. Safety glasses
b, a, d, e, c
It is the actions and measures that are used to lessen or eradicate the risk harbored by biological agents or toxins
Biorisk Management
Rearrange the following from most effective to least effective:
a. Engineering controls
b. Administrative controls
c. Elimination
d. PPE
e. Substitution
c, e, a, b, d
Refers to the work environment that reduce or prevent exposure to hazards
Engineering controls
Can be in the form of policies, standards and guidelines used to control the risk
Administrative controls
Used to effectively reduce risks
Practices and Procedures
Worn by the person to shield themselves from hazardous agents in the laboratory
PPE, or personal protective equipment
Identify which risk group is the following based on the description:
- no or low individual and community risk
- a microorganism that is unlike to cause human or animal disease
Risk group 1
Identify which risk group is the following based on the description:
- moderate individual risk, low community risk
- A pathogen that can cause human or animal disease but is unlikely to be a serious community hazard
- treatment and prevention are available and spread of infection is limited
Risk group 2
Identify which risk group is the following based on the description:
- high individual risk, low community risk
- 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
Identify which risk group is the following based on the description:
- high individual and community risk
- a pathogen that usually causes serious human or animal disease and can be transmitted from one individual to another, directly or indirectly
- treatment and prevention are not usually available
Risk group 4
Identify the biosafety level: Microbes not known to consistently cause disease in immunocompetent adult humans or minimal potential hazard to laboratory personnel and the environment
BSL-1
Identify the biosafety level: Microbes pose moderate potential hazard to personnel and the environment
BSL-2
Identify the biosafety level: Indigenous or exotic microbes that may cause serious or potentially lethal disease via inhalation
BSL - 3
Identify the biosafety level: Exotic agents that pose a high risk of aerosol-transmitted lab infections and life threatening disease that’s often fatal for which there are no vaccines/treatment
BSL - 4
Identify the biosafety level based on lab type: deals with those well-characterized agents which pose minimal potential hazard to lab workers and the environment
BSL - 1
Identify the biosafety level based on lab type: used to study the moderate-risk infectious agents or toxins to personnel and environment, dangerous if swallowed, inhaled or exposed to the skin
BSL - 2
Identify the biosafety level based on lab type: used to study the organisms that can cause serious and potentially lethal disease via inhalation route
BSL - 3
Identify the biosafety level based on lab type: used to study those microorganisms that are aerosol-transmitted and can cause severe to fatal diseases in humans for which there are no vaccines or treatments
BSL - 4
The intentional release of toxic biological agents to cause illnesses or death in people, animals, or plants
Bioterrorism
