At the moment, the guidelines insist that we all wash our hands often using soap and water, and dry them thoroughly. Outside our homes and where hand washing facilities are not available, hand sanitiser should be used. As an employer or business owner, it is your responsibility to provide hand sanitising facilities at entrances/exits, in washrooms, where goods, equipment and merchandise are handled and in meeting rooms. These solutions should be in place before you reopen.
