Which option is NOT a common exposure pathway to biological hazards?

• A. Sound waves
• B. Air
• C. Water
• D. Vectors

Answer: (A)

Exposure to biological hazards happens when a medium that can carry pathogens brings them into contact with a person. The common routes are through air, which allows inhalation of infectious aerosols or droplets; through water, which can transmit pathogens via ingestion or contact; and via vectors, living organisms like mosquitoes or ticks that transfer pathogens from one host to another. Sound waves, on the other hand, are a form of energy that travels through a medium but does not carry biological agents to people. They don’t serve as a carrier for pathogens, so they are not a typical exposure pathway for biological hazards.
