Always wear antibacterial soap and then a mask. Antibacterial soap can reduce the risk of contamination. If you feel that you need to remove the mask for any reason, it is vital that you wash your hands before removing the mask and then put it on again.
In order to fit properly, make sure it covers your mouth and nose. It may be a little uncomfortable, but this is for your personal safety and the safety of the clean room.
After placing the mask on the nose and mouth, check for openings on the side that may allow air to escape.
Place the mask firmly on your face and start breathing from your nose and then your mouth. When working in a clean room and working with hazardous materials, it is very important to breathe through the nose, because the nasal hair will also help filter particles instead of sucking them directly into the lungs through the mouth. Exhaling through the mouth and mask allows the air to escape faster and release the pressure.
When in a clean room or any other controlled environment, follow the steps below to ensure you are protected from harmful particles or smoke and reduce the risk of contamination.
