Follow the CDC and state guidelines; it's your civic duty to nation, state and community.to do so.
Even if not prohibited, social distancing protects you and your loved ones, as well as others. Follow your conscience.
But some clipboards to sign upon, and seats upon a patio, well separate may be acceptable. Being outside (e.g.: on a patio) and/or A number of feet away from one another at a table also decrease risk. Parties should not face each directly (i.e.:they should be at <90 degrees from each other), so they don't exhale directly into someone else's inhalation space.
A paper mask (general medical, not necessarily N95) might also be a good idea, assuming the CDC recommends. Masks should be handled only from the side facing one's own mouth, with washing/sanitizing before and after also helps.
I always carry hand sanitizer, and may use it multiple times during a signing session - even before the COVID-19 crisis.
One never eliminates the risk,; such risk can only be reduced. Combining multiple measures and good, consistent hygiene habits (e.g.: hand-washing) can help keep many people safe.
Latex/vinyl gloves are contra-indicated, due to the longer life of virus particles on such surfaces.
