The measure imposed by the French government will require the use of face masks in shops, banks and shopping malls. They were already compulsory in many other indoor spaces like cinemas, museums and places of worship.
There are exceptions to the law.
Employees who interact with the public are included in the law and will have to wear masks. But other companies are free to impose their own rules on mask wearing, following guidelines from the Labor Ministry.
Enforcement is left to the people running the various establishments, with authorities only providing them with a sign saying that masks are compulsory.
Police can fine people who don't wear masks when required a sum of €135 ($155).
