BIOSAFETY IN A MICROBIAL LABORATORY

What is the primary goal of biosafety in a microbiology laboratory?

• Enhancing the growth of microorganisms

• Protecting laboratory personnel and the environment

• Promoting the use of hazardous chemicals

• Ensuring efficient data collection

Which of the following is NOT an example of a biosafety practice or measure in a microbiology laboratory?

• Biosafety cabinets

• Personal protective equipment

• Vaccination of laboratory personnel

• Lab notebooks

Biosafety levels (BSL) are used to:

• Classify microorganisms based on their size

• Determine the optimal temperature for microbial growth

• Establish guidelines for handling microorganisms safely

• Rank microorganisms based on their economic importance

What is the highest biosafety level (BSL) reserved for?

• Low-risk agents

• Moderate-risk agents

• High-risk agents with limited treatments available

• Highest-risk agents posing a severe threat to human health

Why is proper containment and disposal crucial in biosafety?

• To protect laboratory personnel from chemicals

• To prevent accidental release of infectious agents into the environment

• To save costs on waste management

• To improve laboratory aesthetics

In a BSL-2 laboratory, what design requirements are typically present?

• Hand washing sinks, eye washing stations, and automatic-locking doors

• Sealed enclosures for all experiments

• Isolated zones within a larger building

• No specific design requirements are necessary for BSL-2.

What is the significance of biosafety levels for research and diagnostics?

• They limit the types of microorganisms that can be studied

• They ensure that laboratory personnel are always vaccinated against all known pathogens

• They enable important research and diagnostic work to be conducted safely

• They prioritize economic interests over safety

Which of the following is an example of a bio-incident related to biosafety?

• A researcher develops a new vaccine in a BSL-4 laboratory

• An outbreak of a common cold in a research facility

• An accidental infection of an epidemiologist with Ebola in a BSL-4 lab

• Routine experiments conducted in a BSL-1 laboratory

Which biosafety level (BSL) is appropriate for handling microorganisms that may cause diseases with limited treatment options?

• BSL-1

• BSL-2

• BSL-3

• BSL-4

Why is training and education of laboratory personnel crucial in maintaining biosafety?

• To increase the cost of running the laboratory

• To reduce the amount of paperwork in the lab

• To ensure that personnel are aware of potential hazards and safe practices

• To encourage laboratory staff to wear stylish lab coats
