The City of Wolverhampton Council has created free printable posters for businesses about face masks for when a new law comes into effect on Friday.
People are being reminded they must by law wear face coverings in shops and supermarkets to help prevent the spread of coronavirus.
The council has also produced a handy, step-by-step guide to show people how they can make their own face covering out of an old T-shirt.
Measures can be taken if people do not comply with the new regulations. Transport operators can deny service or direct someone to wear a face covering. Shops and supermarkets will be expected to encourage compliance with the law and can refuse entry. In all cases, if necessary, the police have the powers to enforce these measures, including through issuing a fine of £100, or £50 if paid within 14 days.
People are also strongly encouraged to wear a face covering in other enclosed public spaces where social distancing may be difficult and where they might come into contact with people they do not normally meet.
Councillor Jasbir Jaspal, the City of Wolverhampton Council's Cabinet Member for Public Health and Wellbeing, said: "We need to do all we can to help prevent the spread of coronavirus and avoid a local lockdown.
“Face coverings do not replace social distancing, good hand washing and good hygiene as the most effective measures we should all adopt in our fight against Covid-19.
"However, there is growing evidence that wearing a face covering in an enclosed space can help protect individuals and those around them from the virus.
"You can buy face coverings from many retailers or make your own at home. They can be as simple as a scarf or bandana that ties behind the head, as long as they cover your mouth and nose and allow you to breathe comfortably.”
