Single Entry Sign: A single entry sign is a sign that indicates that only one person can enter the room at a time. This notice is particularly important in rooms with limited capacity to limit the number of people in the room and thus increase safety. Single entry signs are commonly used in doctor's offices, therapy centers or laboratories and can be made of different materials such as PVC, aluminum or self-adhesive foil. They are available in different sizes and can be individually printed as required. If you are looking for a single entry sign, make sure it is legible and has a clear message so people follow the rules and stay safe.
