During instances of poor air high quality, many people choose to cover their mouth and nose to protect themselves from breathing in wildfire smoke. Nonetheless, not all masks and facial coverings really protect the lungs from the harmful respirable particles present in wildfire smoke. Right here’s a breakdown of the supposed use and stage of protection offered by each:
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’re 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 don’t seem to be designed to forestall the inhalation of respirable particles present in smoke. Although they may look the same, dust masks aren’t respirators and shouldn’t be used for that purpose.
N95s and P100s: These respirators have sets of straps and type a tight seal to the face. The entire respirator is made of filtering material. N95s are the commonest, with P100s being more protective (similar to a HEPA filter). Each types can usually be found in hardware stores and different retail outlets. These respirators are certified 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 appropriately, these respirators are efficient at filtering out the small respirable particles present in wildfire smoke. However, they do not filter out fumes and gases; for that, see the subsequent type of respirator listed.
Half-face or full-face respirator: In contrast to N95s and P100s, which are disposable, half-face and full-face respirators offer a decent-fitting, versatile facepiece with exchangeable filter cartridges. N95 particulate filters or purple (P100 or HEPA) filter cartridges will protect in opposition to particulates in wildfire smoke. When used with a combination filter that has an natural vapor cartridge, these respirators would additionally protect in opposition to harmful fumes and gases. However, neither these respirators nor N95s provide oxygen.
Steps for Utilizing an N95 or P100 Respirator Appropriately
Place the respirator over your nose and under your chin, with one strap below the ears and one strap above. In case you’re wearing a hat, place it over the straps.
Pinch the metal nose clip tightly over the top of your nose.
Replace the respirator when it turns into damaged, soiled or more troublesome to breathe through. It could be needed to make use of a recent respirator daily.
For a respirator to provide protection, it should type a tight seal across the mouth and nose. Facial hair doesn’t enable a decent fit, so wearers must be clean-shaven. Respirators can improve risk for other medical situations because it’s more tough to breathe by means of them. When you really feel dizzy, lightheaded or nauseous, first tell someone, then go to a less smoky space, remove your respirator and search medical attention.
