Nevada Gov. Steve Sisolak has yet to confirm when casinos will be able to reopen, but operators are already preparing for the day they’ll have to reassure guests their properties are clean and safe amid the virus outbreak.

MGM Resorts International, Las Vegas Sands Corp. and Wynn Resorts Ltd. have all discussed plans for more expansive cleaning measures within the last week, including the use of thermal screening, masks and social distancing.

This comes as Culinary Local 226 is negotiating with resorts amid the shutdown, seeking an enhanced cleaning standard for all areas of casinos.
