Mask Requirements While at Work or Engaged in UC ANR Activities (For the Period of December 15, 2021 to January 15, 2022) 1. All persons must wear a mask indoors, regardless of vaccination status. 2. Persons who are not fully vaccinated for COVID-19 must wear a mask when working indoors, when sharing a vehicle for work, or crowded outdoor settings in areas of high transmission of COVID-19. 3. At locations in Counties which are subject to a state or local Public Health Order that requires all persons to wear a mask indoors, all persons must comply with health orders while engaged in UC ANR work or other activities. “Fully vaccinated” means the employee has provided UC ANR with documentation that they have received both doses of a two-dose vaccine, or one dose of a single-dose vaccine and at least 14 days have elapsed since the final dose. Volunteers or program participants may “self-attest” their vaccination status while engaged in UC ANR activities. There are also some settings where public health orders require masks for all persons, regardless of vaccination status, such as while using public transit or indoors in schools or other youth settings. Any person who is not required to wear a mask may choose to wear a mask in all settings, indoor or outdoor, unless it would create a safety hazard. UC ANR will provide masks for employees, volunteers, and program participants to use, or persons may use their own mask, for comfort and convenience, as long as it meets these conditions: • is made of a tightly woven fabric or non-woven material, • has at least two layers, • has no visible holes or openings, and • must cover the nose and mouth.
