If your business or venture has a physical location you will have some responsibility to ensure people know how they remain as safe as possible. Covid signage that is clear and lasting is needed. A properly carried out risk assessment should highlight your needs. There are also resources online that may help such this from East Suffolk Council .

Even before someone sets foot within your premises there is guidance that can be given. Signs to direct a delivery person to an allotted spot will prevent confusion in the future. Regardless of the size of your premises there will be a maximum occupancy, this is best communicated early and clearly with a sign. If the property has 2 or more doors you could direct in and out traffic to different paths.

Once inside, in a contained space, there is more to think about. Reminding staff and customers about their responsibilities is key. You can make things easier by organising flows of people into one-way systems with stickers and signs. Even clear directions to common destinations helps, reducing corridor traffic.
