You still have a duty to protect employees under OSHA’s General Duty Clause which states:
“Each employer shall furnish to each of his employee’s employment and a place of employment which are free from recognized hazards that are causing or are likely to cause death or serious physical harm to his employees”
It is best to minimize hazards using what is called the Hierarchy of Controls. Eliminate hazards, substitute methods and approaches, use engineering controls, administrative controls, and lastly require the use of PPE to protect workers.
If you cannot engineer the hazard out, look at administrative controls as the CDC suggests; Wash hands, use hand sanitizers, clean/disinfect the work area, tools etc. maintain the six-foot distancing rule, etc.
