From today it is mandatory to wear face coverings in shops, retail and other indoor settings in Ireland.
Staff must also wear face coverings unless a partition or a two-metre distance is in place between customers and staff.
People who do not wear a face covering or anyone who ignores a request to wear one can face a fine of up to €2,500 and/or up to six months imprisonment.
Other indoor facilities in which customers must now wear face coverings include hairdressers, cinemas, libraries, bingo halls and museums.
