Mask classification

There are several types of masks on the market that can be divided:

A For civil use

B For medical use

C For surgical use

 

A For civil use

They can be produced and placed on the market without any certification and must not comply with any filtering standard.

B For medical use

They must be certified and comply with EN14683

These masks are tested in the sense of exhalation. from the inside out. The tests evaluate the effectiveness of bacterial filtration and allow to establish the compliance of the masks with the following regulations:

  • European standard EN 14683: based on this standard, the level of effectiveness of a mask can be of four types: type I, type II, type IR and type IIR.
  • Type I: bacterial filtration efficiency greater than 95..
  • Type II: bacterial filtration efficiency greater than 98..
  • Type R: European legislation also provides for a test of resistance to projection, according to which the masks can be of type IR and IIR. IIR masks are the most resistant ones.

C For surgical use

They must be certified and comply with the EN14683 standard. All that is said for the medical sector and STERILITY is added.

To proceed with the sterilization it is necessary to use a Pasteurization system that keeps the masks at a temperature of 72 for at least 90 minutes..

The masks can also be sterilized chemically using Ethanol oxide and keeping the masks in drying for at least 15 days.

Sterile packaging requires that the mask be packaged one at a time. 

 

Proper Use

There are some precautions to be taken when wearing a surgical or protective mask. Here are the most important:

  • Remove the mask from the packaging and place it on your face and stretch it, depending on the model, by pulling only on the elastics or laces.
  • Check that the orientation of the mask is correct: the mask generally has an internal finger that must be placed and shaped around the bridge of the nose. The markings affixed by the manufacturer, on the other hand, are generally found on the external surface of the mask. If there are no markings, rest the most padded part of the mask on the face..
  • Open the mask well, rest it on the face so that it covers the nose, mouth and chin, and fix it by passing the elastic bands or laces behind the top of the head and the nape.
  • In the case of protective masks, to check if the mask has been put on correctly, just cover the filter with your hands and inhale slowly: if the mask adheres to the face, it means that it is well positioned, while if it does not adhere, it means that you do not create a air gap, which the air continues to filter inside, and which has therefore not been put correctly.
  • Once the mask is worn, it will no longer need to be moved or re-positioned until it is removed.
  • As for disposal, the disposable masks must be immediately deposited in the appropriate containers, immediately after being removed.
  • Change mask regularly: at least every 3 hours for surgical masks, or sooner if you have received splashes of bioligamic liquids; every 3-8 hours for protective masks.
  • Wash your hands before and after putting on the mask.
