Importance of PPE

According to the hierarchy of controls by the National Institute for Occupational Safety and Health (NIOSH), PPE is recommended to be the last level of defense to prevent occupational injuries, illnesses, and fatalities, but some businesses combined it with other control measures to ensure a safe and healthy environment for their workers.

Here are some benefits of using PPEs:

• prevent unnecessary injury in the workplace;

• protect employees from excessive chemical exposure;

• prevent the spread of germs and infectious diseases including COVID-19;

• improve employee productivity and efficiency.
