A safety or security sign is a graphical representation of hazards and mandatory behavior/actions to avoid them. You would have come across several types of these signs at your workplace, restaurant, shopping mall, or any other public place. Not all signs are made the same; each one has a particular purpose and conveys a specific message. This article lists some of the common types of safety and security signs. Prohibition signs As the name suggests, these signs are used to prohibit people from doing something or entering a particular area. In most cases, these signs constitute a red circle with a diagonal line through it. The “No Smoking” sign is one of the most common examples of a prohibition sign. Emergency signs These safety and security signs come in handy during an emergency as they indicate emergency exits, escape routes, first aid equipment, or other safety equipment. Under a situation like a fire in a building, residents can find their way to emergency-related facilities or evacuate the area using fire exits and fire doors with the help of these signs. Danger signs In certain industrial areas, not taking proper precautions can lead to life-threatening repercussions. Danger signs are used to represent potentially hazardous areas or conditions.
