(WJW) – Costco and Home Depot are limiting the number of customers in their stores and implementing other changes to help prevent the spread of the coronavirus.

Starting Friday, Costco will allow no more than two people to enter any of its warehouses with each membership card.

“This temporary change is for your safety and the safety of our employees and other members, and to further assist with our social distancing efforts,” the company’s website states.

Home Depot has also issued some new shopping guidelines.

Stores will limit the number of customers inside at any given time. The stores will also eliminate major spring promotions to avoid high levels of traffic.

Social distancing markers have been placed at counters, along with signage throughout the stores.

Store hours have been adjusted to close daily at 6 p.m. to give staff more time to perform cleaning and restock shelves. Opening hours will not change.

In addition, thermometers will be distributed to associates in stores and distribution centers, and employees will be asked to perform health checks before reporting to work.
