Final answer:
An N95 respirator is not recommended for workers with asthma due to its tight fit and the difficulty it can present in breathing. A PAPR is a better option for those with respiratory issues. Surgical masks and full-face respirators also have their limitations in terms of protection and breathing resistance.
Step-by-step explanation:
The type of respirator that is not good for workers with asthma is the N95 respirator. This is because an N95 respirator can make it more difficult to breathe due to its tight fit and the effort required to pull air through the filter material. Workers with asthma or other respiratory conditions may find it challenging to use these respirators.
A PAPR (Powered Air-Purifying Respirator) is often a better choice for those with respiratory issues, as it does not require the same level of effort to breathe. The device uses a battery-powered blower to pull air through filters.
A surgical mask does not provide the same level of protection as a respirator because it is loose-fitting and is primarily designed to protect others from the wearer's respiratory emissions rather than protecting the wearer from external particles.
A full-face respirator with a tight seal may also be difficult for someone with asthma, as it needs a snug fit to be effective, which can make breathing more difficult for those with respiratory issues.
