PPE Masks

Updated: January 2025

Face masks shield the nose and mouth, and some also have an attached eye shield. Face masks "catch" some of the droplets created when talking, coughing or sneezing, and protect the nose and mouth from splashes of body fluid.

Investigation of past influenza pandemics provides little evidence that the use of face masks by the general public is effective in preventing the spread of the pandemic virus. However some studies have shown that mask use (in conjunction with other measures) may significantly reduce the spread of influenza-like illnesses.

Nevertheless face masks can be considered for use in your pandemic plan for:

• distribution to employees for use during an outbreak of a respiratory illness. When worn they may reduce the chance of infectious droplets / body fluids landing directly on the mouth and nose, and prevent people touching their mouth and nose with potentially contaminated hands.
• employees who are unwell, coughing or sneezing, and thus reducing viral contamination of the environment.
• responders - who will assist those who are sick in the workplace, until they are able to reach medical help.

Types

There are a number of different designs:

a. b.

c.

• a. “standard surgical” type, with two sets of ties and a moldable nose bridge
• b. Pre-molded, held on by a single elastic band
• c. Pleated, held in place with ear loops Face masks are designed for single use only and should be disposed of after use. Some have an attached eye shield.

Some face masks are approved as medical devices (by national regulatory authorities such as the US Food and Drug Administration). The approved masks provide a specific level of protection against blood and body fluids. They are known as surgical, dental, medical procedure, isolation, and laser masks.

Limitations

Disposable face masks cannot be reused. They are ineffective when wet.

Face masks fit loosely around the face and allow air to pass around the mask. They do NOT prevent inhalation of infectious particles. See Respirators.
