Respirators refer to devices designed and used for protection against inhalation of harmful air or airborne particles such as fumes, dust, gasses, and vapors. N95 respirators are one of the many varieties of respirators on the market. They are meant for general use. They can be used by the public, health workers, industrial workers, or in workplaces that require workers to protect themselves against harmful substances and gasses. There are other brands that are more suited for use by military personnel and other heavy users.
N95 is a non-reusable air filtering respirator capable of filtering small airborne particles with diameters of up to 0.1 microns. Their filter efficiency is very high at approximately 95 percent. Instructions on usage must be followed to ensure that the protection gained from the item is high enough. For example, one should only get into a work area after they have confirmed that the item fits properly on the face and is air tight along the sealing surface.
Most manufacturers specify dressing procedures and necessary seal checks that one must do. Not all products from different manufacturers are the same or have the same donning or seal check procedures hence one should not assume. Making such assumptions can lead to exposure to the very substances one is trying to protect themselves from. Items that become difficult to breathe through due to damages or soiling should be replaced immediately.
There are many different settings in which these devices can be employed. Animal handlers, researchers, and health practitioners are some of the users. All work places with contaminants capable of being blocked using the devices are the major places of application. Employers may also demand wearing of this safety gear by their employees. In such as case, the workers have to go for the fit test and training program held annually in the United States.
Such trainings can be undertaken online without having to visit the training facilities. After taking the online training, one can call an inspector to come and conduct a fit test. Since these devices are meant to be used only once, they must be discarded immediately they are removed. It is an offence to re-use the item under certain jurisdictions.
Certain limitations are associated with these devices and users should know about them. One of the limitations is that they do not provide protection against chemicals. The efficiency of the device is sometimes reduced by facial hair. The hair prevents the sealing surface from forming a tight seal. Protection against certain hazards like silica, lead, and asbestos is not possible.
There are also certain concentration levels beyond which the device should not be used. For example, if the infectious substance has a concentration ten times the specified limit, the equipment cannot be of any use. In cases where exposures do not exceed the lowest limit for which the equipment must be worn, the employee may decide to wear it voluntarily.
After leaving the site of contamination, the exterior of the device should not be touched. This is because the fabric of the device may be containing contaminants. One should wash their hands properly with the necessary detergent after leaving the work area.
