What other preventative measures can you take to protect yourself from airborne substances?

Using a mask is just one preventative measure you can take to protect yourself from respiratory pathogens, dust and harmful airborne substances. However, it is recommended to not rely on disposable KN95 protective masks alone to provide an adequate level of protection.

Here are a few more steps you can use, along with the use of safety face masks to protect yourself from harmful substances in the environment: 

1. Perform hand hygiene frequently, using soap and water (where possible) or an alcohol-based hand rub.

2. Try not to touch your face, especially your eyes, nose and mouth with unwashed hands.

3. Cover nose and mouth with a bent elbow or paper tissue when coughing or sneezing and dispose of tissue immediately after use.

4. Keep surfaces clean and disinfected.
