If you are working alone with no possible contact with others, you do not need to wear a mask.	Low Transmission Risk

Dust mask, foreign system non-NIOSH approved filtering facepiece respirator (such as KN95), or medical procedure masks are recommended. At the minimum a cloth face covering is required at all time. Use multiple engineering and administrative controls together to reduce frequency and risk of touch and airborne transmission between humans.	Medium Transmission Risk
