The importance of Face mask,PPE to stop Coronavirus

When to use a mask?

  • If you are healthy, you only need to wear a mask if you are taking care of a person with suspected 2019-nCoV infection.
  • Wear a mask if you are coughing or sneezing.
  • Masks are effective only when used in combination with frequent hand-cleaning with alcohol-based hand rub or soap and water.
  • If you wear a mask, then you must know how to use it and dispose of it properly.
  • If you’re sick and need to be around others, properly wearing a mask can protect those around you from contracting your illness.

One 2013 study looked at how masks could help people with the seasonal flu limit spreading it when they exhale small droplets containing the virus. Overall, researchers found masks led to a more than threefold reduction in how much virus people sprayed into the air.

The best way to prevent spreading covid-19 is to avoid being exposed to this virus. However, everyday hygienic preventive actions, such as hand washing and maintaining at least 2 meters of social distancing, using the right PPE to help prevent the spread of respiratory diseases.

When and how to wear medical masks to protect against coronavirus?

  • Before putting on a mask, clean hands with alcohol-based hand rub or soap and water.
  • Cover mouth and nose with mask and make sure there are no gaps between your face and the mask.
  • Avoid touching the mask while using it; if you do, clean your hands with alcohol-based hand rub or soap and water.
  • Replace the mask with a new one as soon as it is damp and do not re-use single-use masks.
  • To remove the mask: remove it from behind (do not touch the front of mask); discard immediately in a closed bin; clean hands with alcohol-based hand rub or soap and water.

N95 Respirators and Surgical Masks (Face Masks)

N95 respirators and surgical masks (face masks) are examples of personal protective equipment that are used to protect the wearer from airborne particles and from liquid contaminating the face.

A surgical mask is a loose-fitting, disposable device that creates a physical barrier between the mouth and nose of the wearer and potential contaminants in the immediate environment. These are often referred to as face masks, although not all face masks are regulated as surgical masks. Note that the edges of the mask are not designed to form a seal around the nose and mouth.

An N95 respirator is a respiratory protective device designed to achieve a very close facial fit and very efficient filtration of airborne particles. Note that the edges of the respirator are designed to form a seal around the nose and mouth. Surgical N95 Respirators are commonly used in healthcare settings and are a subset of N95 Filtering Facepiece Respirators (FFRs), often referred to as N95s.

The similarities among surgical masks and surgical N95s are:

They are tested for fluid resistance, filtration efficiency (particulate filtration efficiency and bacterial filtration efficiency), flammability and biocompatibility.

They should not be shared or reused.
