Respirators
A disposable respirator protects you from breathing particulate hazards including airborne viruses and bacteria. A disposable respirator:
- Protects you from breathing in particulates, including infectious viruses and bacteria
- Seals tightly to your face so that inhaled air is drawn through the filter
- Requires a “fit test” to ensure that it will seal properly to your face
- Has a NIOSH rating printed on the mask (typically “N95”)
- Has two straps – one that fits behind the head, the other behind the neck – and may have an external exhalation valve
Surgical masks
A surgical mask protects others from the airborne droplets you produce. A surgical mask:
- Prevents you from spreading airborne droplets (e.g., spit and mucous) to others around you
- Does not seal tightly to your face, and is not designed to filter particulates from the air you breathe
- May have a moisture barrier to reduce the risk that splashes of body fluids will reach your nose or mouth
- Is used to protect people around you
- Is NOT a respirator An appropriate respirator must be worn when required by a risk assessment.

You should put your respirators over your nose and mouth. The nose piece has to be placed at the top of your nose, so it is important for you to check that the metal nose piece is in the right location. But if it is not over your nose, flip your mask around until it is.
