Risk Levels and Respiatory Protection
Risk Levels
Worker risk of occupational exposure to SARS-CoV-2, the virus that causes COVID-19, during an outbreak may vary from very high to high, medium, or lower (caution) risk.
The level of risk depends in part on:
- the occupations with each industry type;
- the frequency of contact within 6 feet of people at work known to be, or suspected of being, infected with SARS-CoV-2; and
- the requirement for repeated or extended contact with persons at work known to be, or suspected of being, infected with SARS-CoV-2
To help employers determine appropriate precautions, OSHA has divided job tasks into four risk exposure levels: very high, high, medium, and lower risk. The Occupational Risk Pyramid shows the four exposure risk levels in the shape of a pyramid to represent probable distribution of risk. Most American workers will likely fall in the lower exposure risk (caution) or medium exposure risk levels.
