Respirator Masks – Have at least a good N95 mask, not just a simple dust mask. A mask will prevent germs carried in the air to enter your body. Keep in mind a mask is only as good as the seal it creates around your nose and mouth. I recommend that you change your N95 mask daily. N95 is a rating provided by NIOSH (National Institute of Occupational Safety and Health) which is a division of the CDC, and it means that 95% of all particulates that are .2 microns or larger will not penetrate the mask. An N100 rating means the respirator will prevent 100% off all particulates that are .2 microns or larger from passing through the respirator. One major issue to consider with any mask or respirator is that over a period of a few days you will have build on the outside of the mask that can slough off onto your clothes. So change your masks regularly.
Facemasks and N95 respirators are devices that may help prevent the spread of germs (viruses and bacteria) from one person to another. They are one part of an infection-control strategy that should also include frequent hand washing and social distancing.
Facemasks and N95 respirators should not be shared. Facemasks and respirators may become contaminated with germs (viruses and bacteria) that can be spread between people.
The following provides basic information about facemasks and N95 respirators.
Facemasks
A facemask 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. Facemasks may be labeled as surgical, laser, isolation, dental or medical procedure masks. They may come with or without a face shield.
Facemasks are made in different thicknesses and with different ability to protect you from contact with liquids. These properties may also affect how easily you can breathe through the facemask and how well the facemask protects you.
If worn properly, a facemask is meant to help block large-particle droplets, splashes, sprays or splatter that may contain germs (viruses and bacteria) from reaching your mouth and nose. Facemasks may also help reduce exposure of your saliva and respiratory secretions to others.
While a facemask may be effective in blocking splashes and large-particle droplets, a facemask, by design, does not filter or block very small particles in the air that may be transmitted by coughs, sneezes or certain medical procedures. Facemasks also do not provide complete protection from germs and other contaminants because of the loose fit between the surface of the facemask and your face.
Facemasks are not intended to be used more than once. If your mask is damaged or soiled, or if breathing through the mask becomes difficult, you should remove the facemask, discard it safely, and replace it with a new one. To safely discard your mask, place it in a plastic bag and put it in the trash. Wash your hands after handling the used mask.
N95 Respirators for Use by the Public
An N95 respirator is a respiratory protective device designed to achieve a very close facial fit and very efficient filtration of airborne particles. In addition to blocking splashes, sprays and large droplets, the respirator is also designed to prevent the wearer from breathing in very small particles that may be in the air.
To work as expected, an N95 respirator requires a proper fit to your face. Generally, to check for proper fit, you should put on your respirator and adjust the straps so that the respirator fits tight but comfortably to your face. For information on proper fit, refer to the manufacturer’s instructions.
The ‘N95’ designation means that when subjected to careful testing, the respirator blocks at least 95% of very small test particles. If properly fitted, the filtration capabilities of N95 respirators exceed those of face masks. However, even a properly fitted N95 respirator does not completely eliminate the risk of illness or death.
N95 respirators are not designed for children or people with facial hair. Because a proper fit cannot be achieved on children and people with facial hair, the N95 respirator may not provide full protection.
People with chronic respiratory, cardiac, or other medical conditions that make it harder to breathe should check with their healthcare provider before using an N95 respirator because the N95 respirator can require more effort to breathe. Some models have exhalation valves that can make breathing out easier and help reduce heat build-up.
ALL FDA-cleared N95 respirators are labeled as "single use", disposable devices. If your respirator is damaged or soiled, or if breathing becomes difficult, you should remove the respirator, discard it properly, and replace it with a new one. To safely discard your N95 respirator, place it in a plastic bag and put it in the trash. Wash your hands after handling the used respirator.
FDA has cleared the following N95 respirators for use by the general public in public health medical emergencies:
3M™ Particulate Respirator 8670F
3M™ Particulate Respirator 8612F
Pasture Tm F550G Respirator
Pasture Tm A520G Respirator
These devices are labeled "NOT for occupational use.”
N95 Respirators in Industrial and Healthcare Settings
Most N95 respirators are manufactured for use in construction and other industrial type jobs that expose workers to dust and small particles. These respirators are evaluated for effectiveness by the National Institute for Occupational Safety and Health (NIOSH), which is part of the Centers for Disease Control (CDC). These are labeled "For occupational use.”
N95 respirators cleared by FDA for use in the healthcare setting are called surgical N95 respirators. These devices meet some of the same performance standards as surgical face masks and are also NIOSH certified to meet the N95 respirator performance requirements.

To increase the protection of your N95 masks. Mix up a protective spray using essential oil ans distilled water. Spray your face and then put on your mask and then spray the out side of your mask. Use caution to avoid spraying your eyes.
Swine flu is very dangerous disease. Its almost fatal. Like its is said, "Prevention Is Better Than Cure", one should cover face with mask to protect from swine flu virus. The N-95 masks are popular. It is basically a surface for entrapment of the virus from outside, so one should wash the mask on a regular basis followed by washing one’s hands and face.

ReplyDeleteA vaccine for Bird Flu is not available. A vaccine against SARS has not even been produced, and it's been over two years since SARS first struck. Think about it logically - according to the medical establishment, even a cure for the common cold has eluded medical science.
