Question 1

Which biological agent is classified as a Category A bioterrorism agent by the CDC due to its high mortality and potential for widespread impact?

Accepted Answer

Bacillus anthracis

Answer

Bacillus anthracis (anthrax) is a CDC Category A agent because it can be easily disseminated, causes high mortality, and requires special public health preparedness.

Question 2

What does the term 'zoonosis' refer to in the context of occupational biological hazards?

Accepted Answer

Diseases transmissible between animals and humans

Answer

A zoonosis is any infectious disease that can be transmitted between vertebrate animals and humans, a significant concern for agricultural and veterinary workers.

Question 3

Which engineering control is most effective for preventing airborne biological hazard exposure in a clinical microbiology laboratory?

Accepted Answer

Biosafety cabinet (BSC)

Answer

A biosafety cabinet (BSC) provides HEPA-filtered, inward and exhausted airflow specifically designed to protect workers from aerosols generated during microbiological work.

Question 4

What exposure assessment tool is used to estimate airborne concentrations of mold in indoor air quality investigations?

Accepted Answer

Spore trap sampling analyzed by direct microscopy

Answer

Spore trap air sampling (e.g., RCS, Burkard, Air-O-Cell) collected on sticky media and analyzed by direct microscopy is commonly used for total airborne fungal spore counts.

Question 5

Under OSHA's Bloodborne Pathogens Standard, which items must be included in an Exposure Control Plan?

Accepted Answer

Exposure determination, implementation schedule, and procedures for evaluating exposure incidents
