Throughout times of poor air high quality, many individuals select to cover their mouth and nose to protect themselves from breathing in wildfire smoke. However, not all masks and facial coverings really protect the lungs from the dangerous respirable particles found in wildfire smoke. Right here’s a breakdown of the supposed use and level of protection offered by each:
Paper dust masks: Also called surgical masks, these loose-fitting masks have only one strap and don’t form a good seal to the wearer’s face. They are designed to cease liquid droplets and aerosols coming out of the wearer’s mouth, not filter the air coming in. With no filter and no facial seal, they don’t seem to be designed to stop the inhalation of respirable particles present in smoke. Though they could look the same, dust masks are usually not respirators and shouldn’t be used for that purpose.
N95s and P100s: These respirators have sets of straps and form a tight seal to the face. The entire respirator is made of filtering material. N95s are the most typical, with P100s being more protective (just like a HEPA filter). Both types can typically be present in hardware stores and different retail outlets. These respirators are licensed by the National Institute for Occupational Safety and Health (NIOSH), so look for “NIOSH” and the designation “N95” or “P100” on the respirator.
When worn appropriately, these respirators are effective at filtering out the small respirable particles found in wildfire smoke. However, they do not filter out fumes and gases; for that, see the following type of respirator listed.
Half-face or full-face respirator: Unlike N95s and P100s, which are disposable, half-face and full-face respirators provide a decent-fitting, versatile facepiece with substituteable filter cartridges. N95 particulate filters or purple (P100 or HEPA) filter cartridges will protect against particulates in wildfire smoke. When used with a combination filter that has an natural vapor cartridge, these respirators would also protect in opposition to dangerous fumes and gases. Nevertheless, neither these respirators nor N95s provide oxygen.
Steps for Using an N95 or P100 Respirator Correctly
Place the respirator over your nose and under your chin, with one strap under the ears and one strap above. For those who’re wearing a hat, place it over the straps.
Pinch the metal nostril clip tightly excessive of your nose.
Substitute the respirator when it becomes damaged, soiled or more difficult to breathe through. It might be crucial to make use of a fresh respirator daily.
For a respirator to provide protection, it must kind a decent seal across the mouth and nose. Facial hair doesn’t permit a decent fit, so wearers should be clean-shaven. Respirators can improve risk for other medical circumstances because it is more tough to breathe by means of them. When you really feel dizzy, lightheaded or nauseous, first inform somebody, then go to a less smoky space, remove your respirator and search medical attention.
