Safety signs are one of the primary methods of disseminating safety information when direct verbal communication is not possible or wanted. These can include hand signals, like those given at an intersection by a traffic cop; audio signals like fire alarms or the bell at railroad crossings; and the use of safety signs, sometimes lighted. Traffic signs, showing everything from motorway numbers to the route of detours; warning signs, like those for hazardous materials or dangerous electrical components; and signs identifying fire exits, fire extinguishers and fire evacuation routes are all also considered safety signs. Wherever there is a risk, it is important that there should be a sign to announce its presence. These signs must always be prominently displayed, easy to read and easy to understand. This is why most countries have adopted a universal set of shapes, colours and symbols, often called pictograms, which are being used worldwide to announce various levels of peril. The internationally recognised colours for safety signs are the same as those commonly known to most people in daily use: red for exclusion or prevention; yellow for caution or watchfulness; green to denote any positive action; and blue, for mandatory signs and to relate data such as the location of a hospital. The shapes of the signs are also standard: circle for a banned action or instruction, triangle for warnings, square and rectangle for emergency and information signs. Together these components give safety signs a recognisable and understandable message that can be useful anywhere.
