How Often Should You Change Your particulate respirator? Disposable respirators are called face piece. However,it’s different from the normal face piece in a way that it can provide more respiratory protection coverage. While the normal single-strapped respirator can provide general dust protection such as during leaf blowing or household dust protection,the n95 respirator can protect airborne particles as small as 0.3 microns. Normal the mask don’t provide a perfect fit to the face as well thereby limiting its protective abilities.
NIOSH has established a guideline which says that dust mask can be reused given that the person is exposed to dust levels less than 200 mg in the span of 8 hours and if the person isn’t working on a biosafety lab. This leads us to the question of how often a person should change his/her respirator. Conditions requiring disposable respirator replacement you usually know by instinct when it is time to replace your dust mask. But if you’re not sure,here are the situations that call for a worker to change his/her dust mask.
Over time,the continuous use ofdisposable respirator can lead to it being soiled or contaminated. When then95 dust mask have become soiled enough,it can hinder with the ability of theparticulate respirator to block off the incoming dust. Moreover,it can also make breathing become difficult since less clean air will be able to pass through the filter.
Respirators usually become easily soiled when the user just puts theface mask down anywhere when not in use. Damagedmask can easily become damaged due to its poor frame integrity. When thedust mask are not properly taken care of,it could become deformed. Holes in the disposable respirator can contribute greatly to its ineffectiveness to provide full protection to its wearer since it can easily allow dirty air to go through the mask and into the nose which it can easily be breathed in.
Broken straps on the dust masks are also an indication that the particulate respirator need replacing. Even if you try fixing it,it’s the ability to completely protect you becomes compromised. It’s better to change it than to risk getting airborne diseases.
Shared dust mask is one of the biggest no-no’s when it comes to ineffectiveness. Germs from other people can easily cling on to the surface of the respirator and it could easily get transferred to you. Even if you’re okay with sharing dust masks with other people,NIOSH strongly discourages you to do this. dust mask used for 8-10 hours straight even if the mask isn’t dirty,if you used it for 8 to 10 hours straight,you should consider changing it. Chances are,a lot of invisible germs may have clung to it without you knowing.
