A respirator is a mask that you wear over your face and can be used to filter the air you breathe. They are generally used during operation under conditions where there are harmful pollutants in the air. It is the most common fan and can also be used once or even reused.
The first thing to do is get a proper test. There are many qualified people who will make sure that your fan fits correctly, making sure that there is no gap around your mask and that it fits comfortably on your face and therefore will not restrict your work. Then, contact your local hospital or Pandemic Pal to find the location of the occupational medicine clinic closest to you. The ventilator can then be placed in the nose and mouth to ensure that the belt is snug but comfortable.
Do a seal test. You should do this every time you put on the fan to make sure contaminants don’t seep around your face. When doing this while wearing a reusable respirator, you should initially cover the exhalation port while breathing out forcefully.
You should not feel the presence of a little air escaping around your face. After that, you can cover the filter cartridges with a deep, strong breath. You should have a hard time breathing and you will not feel the air surrounding your face. With a fan, you can simply cover the entire mask with your hands and inhale and exhale forcefully to make sure there are no air leaks around your face.
You can work as usual. When used correctly, the ventilator should not obstruct your breathing and should not obstruct your vision. If this happens, configure it to have a different respirator.
If you need a special respirator, you can simply choose a half-mask respirator to meet your specific needs.
Check the respirator frequently before and after use. It must be free of cracks, tears and abrasions and the filter must be clean in place. After that, replace the fan filter cartridges regularly. It can be every working day if you use the fan in dirty conditions.
