Question

In a qualitative fit test, a challenge agent is used outside the respirator to see if the wearer of the respirator can detect it. One of the agents used is ____________.

a) Strawberry scent
b) Banana oil
c) Mint flavor
d) Lavender aroma

Answer 1

Banana oil, also known as isoamyl acetate, is a common challenge agent used in qualitative fit testing for respirators to test the seal and effectiveness.

Step-by-step explanation:

In a qualitative fit test, a challenge agent is used outside the respirator to determine if the wearer can detect its presence, thereby testing the respirator's seal and fit. One such agent commonly used is banana oil (isoamyl acetate), which has a distinctive and recognizable smell. If the wearer can detect the smell of the challenge agent, this indicates that the respirator may not be providing an adequate seal against potential airborne hazards. It is known to soothe skin, slow down hair loss, moisturize scalp, prevent dandruff and provide the skin a protective shield against pollution and UV rays.
