What is olfactory fatigue?

• A. Loss of taste sensation after continuous exposure
• B. Loss of smell sensation after continuous exposure
• C. Loss of hearing after continuous exposure
• D. Loss of sight after continuous exposure

Answer: (B)

Olfactory fatigue refers specifically to the diminished ability to detect odors after prolonged exposure to a particular scent. This phenomenon occurs when the receptors in the nasal cavity become desensitized due to continuous stimulation by an odorant. As a result, individuals may find that they cannot perceive the smell even though the odor is still present in the environment. This is particularly important in hazardous materials situations, as it can lead to a failure to recognize the presence of dangerous fumes or chemicals once the person has been exposed for a period of time. Recognizing olfactory fatigue is vital for safety awareness and taking necessary precautions in environments where hazardous materials are present.
