Losing the olfactory sense of taste or smell can indeed present challenges when conducting respirator fit testing, particularly if you are using qualitative fit testing methods that rely on the wearer's ability to detect test agents by taste or smell. While it is a relatively rare condition, anosmia (the loss of the sense of smell) or ageusia (the loss of the sense of taste) can occur due to various factors, including medical conditions, medications, aging and has been widely reported as a symptom of COVID-19. Here are some concerns and considerations when fit testing individuals with these conditions:
In conclusion, while the loss of olfactory sense of taste or smell can pose challenges during respirator fit testing, there are alternative methods like quantitative (QNFT) fit testing and considerations that employers can employ to ensure the safety and protection of workers in such cases. The key is to prioritize accurate fit testing and to adapt to the specific needs and conditions of each individual while maintaining a commitment to workplace safety.
