The nation’s largest retailer is making more changes in response to the coronavirus pandemic.

Walmart announced that starting Saturday it would allow only five customers per 1,000 square feet of store space, slashing occupancy to about 20 percent. Once a store reaches capacity, shoppers will be admitted on a “1-out-1-in” basis, the company said.

“While many of our customers have been following the advice of the medical community regarding social distancing and safety, we have been concerned to still see some behaviors in our stores that put undue risk on our people,” said Dacona Smith, Executive Vice President and Chief Operating Officer, Walmart U.S. “We want to encourage customers to bring the fewest number of people per family necessary to shop, allow for space with other customers while shopping, and practice social distancing while waiting in lines.”

Store associates will also be marking a queue at a single-entry door, typically the grocery entrance, and direct customers through there. Customers will be directed to exit through a different door than they entered.

Once inside the store, markers will direct shoppers to one-way movement through the aisles to help customers avoid close contact.

Gloves and masks will be made available to employees who want them. The retailer had already closed stores overnight for cleaning and restocking and installed sneeze guards and social distance markers in its locations.
