Notice signs for a variety of announcements

Signs are part of an array of safety supplies and equipment for commercial establishments, municipalities, and private citizens. Posted announcements provide warnings, information, or directions to customers and the general public as a heads-up about their surroundings. Some signs let people know where they can’t go, such as restricted-access areas, or where they should go, such as emergency exits. Other signs let people know they’re being monitored in high-security areas, or that they should stay off the grass. Others help homeowners warn people not to trespass or solicit on their property.

Visibility of notice signs

The signs come in high-contrast backgrounds and lettering. Some contain background or letters in red, the universal color for stop, such as no admittance. Others are in yellow, providing the universal color for caution, to let people know they may need security IDs or other credentials to access certain areas. Blue backgrounds with white lettering are universal health-related notices, like the locations of hospitals or wheelchair ramps. Many posted announcements include lettering and backgrounds that include high-contrast red on white, black on white, and black on yellow. Other signs contain icons behind a crossed red circle, prohibiting firearms, dogs, bicycles, and cellphones, for example.

Signs that go with other safety systems

Posted announcements sometimes work in conjunction with other safety precautions. Exit and employee-only signs may be part of a belt and stanchion safety system for queuing or guiding people in commercial establishments or public places. Fire-alert signs may be posted where fire extinguishers or fire-call boxes are located. Construction-entrance or driveway-only signs may be posted along with traffic signs and cones as additional alerts for motorists.

Posted announcements in an array of sizes

Signs come in various sizes for either outdoor or indoor applications. Prominent dimensions include the following:

• 10 x 14 inches
• 14 x 20 inches
• 18 x 12 inches
• 7 x 10 inches

Several other notice sign sizes are available as well, for specific applications and the sake of convenience.

The durability and strength of notice signs

Because many signs have to be posted outdoors, they are made of materials that can stand up to the elements. Most signs consist of aluminum or rigid plastic, so they’re rust and corrosion-resistant. Each of these materials also resists bending in high winds and readily accepts enameling of different colors that remains bold and bright regardless of shifting seasons.
