Recently, there have been many misconceptions about various respirators, especially N95 and P2 masks. The variations in respirator regulations and their uses have been identified and explained.
How Similar Are N95 and P2 Masks?
Yes. Although a P2 grade is generally seen as acceptable and secure, what does it actually mean? P2 has to do with the AUS/NZ 1716:2012 standard for respiratory protection equipment ratings in New Zealand and Australia. The respirator (or face mask) must meet the N95 standard, also known as NIOSH-42CFR84, in order to protect the user from at minimum 95% of particles in the air. The masks are frequently used to lessen exposure to infection, coal dust, asbestos, silica, and wildfire smoke.
How Safe Is a Valved P2 Respirator?
Yes, P2 respirators with expiration valves make it easier to exhale while limiting moisture build-up for the user. These respirators are ideal for prolonged use and strenuous working conditions. It is crucial to highlight that valved P2 face piece are not advised for medical use since there is a higher risk of disease transmission through the exhalation opening if the wearer is affected.
How frequently should a P2 Respirator be replaced?
The question of whether and how frequently to replace your P2 respirator is unclear. As a general rule, you should change your P2 mask if inhaling becomes challenging or if you detect a change in smell or taste through the filter.
This will depend on the user, usage, and environmental factors. Be aware that the presence of oil or oil droplets reduces the filter’s effectiveness. They have a pre-shaped nose cushion, a contoured face seal, and twin straps for a secure fit in difficult circumstances. They are made to be comfortable for extended periods of time.
Differences Between a Cup & Flat Fold P2 Mask
There isn’t much of a functionality difference between P2 cup and flat fold respirators apart from cosmetic variations. With a flat fold, the storage size will be smaller, which makes them perfect for stowing inside a glove box or helmet. It all comes down to what you personally favour. Because there is more room between the masks and the wearer’s face with cup respirators, some individuals prefer them
Any respirator’s filtration rating is based on how well your face and the mask seal together.
The degree of safety that a mask can provide will be significantly reduced if it is worn over untrimmed facial hair. Without being screened, particles will indeed be able to pass through the opening between the hair and the mask.
Respirators with a pliable silicone face piece establish a tighter seal against unfiltered materials reaching the airways by moulding to facial features.
Can I Use N95 Masks in Australia?
The AS/NZS used in Australia and the NIOSH used for face masks in the USA are extremely comparable. To make sure you are appropriately protected and the items are being supplied through legitimate means, it is advised that you utilize products authorized in the specific country or region in where you are located.
Some countries are permitting the use of masks that have been certified to equivalent criteria during the COVID-19 issue (e.g., EN, NIOSH, AS/NZS). You should never use a mask that doesn’t have accreditation or standards marks on the device or package.
