An exit sign is a crucial safety feature in buildings and facilities that guide individuals to safe exits in case of an emergency. The importance of these signs cannot be overstated as they help prevent panic, confusion, and injury in critical situations.
History of Exit Signs
The first recorded use of exit signs dates back to the early 1900s when the United States began requiring fire safety signs in public buildings. However, these signs were not standardized yet, and companies used different designs and colors for their exit signs.
In the 1970s, the United States standardized exit signs to a green background with white letters that spelled out “EXIT”. Since then, different countries have adopted their versions of exit signs, but most follow the green and white design as it stands out in dark or smoky conditions.
Types of Exit Signs
There are two significant types of exit signs: electrical and non-electrical signs. Electrical exit signs use electricity to power the light and are commonly found in larger buildings, including hospitals, schools, and stadiums.
Non-electrical exit signs are also known as photoluminescent or glow-in-the-dark exit signs. These signs absorb light and store it, which allows them to glow in low-light environments. These signs require no electricity to glow, making them energy-efficient and ideal for smaller businesses, residential buildings, or areas with limited power access.
Where to Install Exit Signs
Exit signs should be positioned in areas that are visible and accessible to occupants within the building. Common locations for exit signs include doors leading to stairwells, elevators, or emergency exits.
The placement of exit signs should follow guidelines set by local and national safety regulations. Typically, exit signs should be placed at least 6 feet above the floor and positioned within 100 feet of each other to provide for easy navigation.
The Importance of Exit Signs
Exit signs indicate the correct path to follow to ensure safe evacuation of a building. In an emergency, every second counts, and exit signs help guide occupants to safety quickly and efficiently. Without exit signs, people may become disoriented or panic, leading to congestion and crowding around exits that could be dangerous.
The use of exit signs is mandatory across all public buildings, including schools, offices, commercial buildings, and industrial facilities. Regular inspections and maintenance ensure that exit signs are always visible, legible, and in working order.
In Conclusion
Exit signs serve as essential safety features in any building or facility. They provide guidance and clarity in emergencies, allowing occupants to evacuate quickly and safely. Their placement and maintenance follow critical guidelines to ensure their effectiveness, making them reliable and necessary in any building’s design or renovation plan.
