The next time you go to the grocery store, the governor wants you to wear a face mask.

Gov. Phil Murphy took the Centers for Disease Control and Prevention’s advisory to wear masks when out in public one step further on Wednesday and made it the rule in New Jersey for customers and workers at essential businesses.

There are exceptions, but Murphy said during his press briefing, “My guidance is, you gotta go out and find something to put on your face before you come in.”

The rule, the governor said, would be enforced by employees asking people who aren’t wearing face masks "to leave.” But the overall enforcement would be “benevolent,” he said.

Murphy also is limiting the number of customers allowed inside stores to 50% of their maximum capacity, to make it easier to practice social distancing. And he’s adding sanitation requirements for essential businesses.

The new rules take effect Friday at 8 p.m.

Here’s a closer look at the changes:

Face masks:

Workers and customers over 2-years-old are required to wear cloth face coverings unless doing so would inhibit the person’s health.

Workers must also wear gloves. The gloves and face masks are to be provided by the business at the business’ expense.

If a customer refuses to wear a mask for non-medical reasons, and one can’t be provided by the business, then the business must decline entry to the person -- unless it sells medication, medical supplies or food. If it sells those items, the business should provide an alternative method -- pick-up or delivery -- for the person to get the goods.

If a person declines to wear a mask for medical reasons, the business’ staff can’t ask the person to show medical documentation verifying their condition.

Safety measures at stores

Essential retail businesses must limit the number of people allowed inside at one time to 50 percent of the stated maximum store capacity.

Designate store hours specifically for high-risk individuals to shop.

Install physical barriers between cashiers or baggers and shoppers.

Require infection control practices -- regular hand washing, coughing and sneezing etiquette and proper tissue usage and disposal.

Provide employees break time for handwashing throughout the day.

Arrange for contactless pay options, pick-up and delivery and make sure these options take into account people who do not have internet access.

Provide hand sanitizer and sanitizing wipes to staff and customers.

Require frequent sanitization of high-touch areas such as restrooms, credit card machines, keypads, counters and shopping carts.

Put signs at the entrance and throughout the store alerting staff and customers to keep six feet of physical distance. And mark six feet of spacing in check-out lines.
