Throughout occasions of poor air quality, many individuals choose to cover their mouth and nostril to protect themselves from breathing in wildfire smoke. However, not all masks and facial coverings really protect the lungs from the harmful respirable particles found in wildfire smoke. Right here’s a breakdown of the supposed use and degree of protection offered by every:
Paper dust masks: Additionally called surgical masks, these loose-fitting masks have only one strap and don’t form a tight seal to the wearer’s face. They are designed to stop liquid droplets and aerosols popping out of the wearer’s mouth, not filter the air coming in. With no filter and no facial seal, they aren’t designed to forestall the inhalation of respirable particles found in smoke. Although they may look the same, dust masks are not respirators and should not be used for that purpose.
N95s and P100s: These respirators have two sets of straps and kind a decent seal to the face. Your complete respirator is made of filtering material. N95s are the commonest, with P100s being more protective (just like a HEPA filter). Both types can usually be found in hardware stores and other retail outlets. These respirators are licensed by the National Institute for Occupational Safety and Health (NIOSH), so search for “NIOSH” and the designation “N95” or “P100” on the respirator.
When worn accurately, these respirators are effective at filtering out the small respirable particles present in wildfire smoke. Nevertheless, they don’t filter out fumes and gases; for that, see the following type of respirator listed.
Half-face or full-face respirator: Not like N95s and P100s, which are disposable, half-face and full-face respirators supply a tight-fitting, flexible facepiece with exchangeable 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 towards dangerous fumes and gases. However, neither these respirators nor N95s provide oxygen.
Steps for Using an N95 or P100 Respirator Appropriately
Place the respirator over your nose and under your chin, with one strap beneath the ears and one strap above. In the event you’re wearing a hat, place it over the straps.
Pinch the metal nose clip tightly over the top of your nose.
Change the respirator when it becomes damaged, dirty or more tough to breathe through. It might be needed to use a fresh respirator daily.
For a respirator to provide protection, it should type a good seal around the mouth and nose. Facial hair doesn’t allow a decent fit, so wearers needs to be clean-shaven. Respirators can improve risk for different medical circumstances because it is more tough to breathe by means of them. For those who really feel dizzy, lightheaded or nauseous, first tell somebody, then go to a less smoky area, remove your respirator and seek medical attention.
