Exit Signs with Arrows vs. Plain Exit Signs: Which is More Effective?
Comparing Exit Signage: Do Arrows or Simplicity Lead the Way to Safety?
Exit signs are a crucial element of building safety, as they guide occupants to safety in the event of an emergency. When it comes to exit signs, there are two primary types: those with arrows and those without. While both types serve the same purpose, there is some debate as to which one is more effective. In this article, we will compare exit signs with arrows to plain exit signs to determine which is more effective in different situations.
Emergency Exit Signs with Arrows
Emergency exit signs with arrows are designed to provide directional guidance to occupants during an emergency. These signs are typically used in larger buildings or complexes where it may be challenging for people to navigate their way to the nearest exit. The arrows on the sign point towards the nearest exit, which can be helpful in a crisis situation.
According to the National Fire Protection Association (NFPA), emergency exit signs with arrows are required in all occupancies other than dwelling units. The NFPA also specifies that the arrows on exit signs must be at least 8 inches in length and point to the nearest exit.
In a study conducted by the University of Michigan, researchers found that exit signs with arrows were more effective at guiding occupants to safety than plain exit signs. The study found that occupants were able to exit a building more quickly when exit signs with arrows were used, reducing the overall evacuation time by 18%.
Plain Exit Signs
Plain exit signs, on the other hand, are simpler in design and do not include any directional arrows. These signs are often used in smaller buildings or rooms where the location of the nearest exit is more apparent. Plain exit signs are also commonly used in areas where there is only one exit, such as a small room or a dead-end hallway.
While plain exit signs are simpler in design, they are still required to meet certain standards set forth by the NFPA. According to the NFPA, exit signs must be illuminated and easily visible from a distance.
Which is More Effective?
The effectiveness of exit signs with arrows versus plain exit signs depends on the location and circumstance. In larger buildings, exit signs with arrows can be beneficial as they provide clear directional guidance, especially in areas with multiple exits. However, in smaller buildings or rooms, plain exit signs may be more appropriate as they are simpler and more cost-effective.
In a study conducted by the Center for Campus Fire Safety, researchers found that the placement of exit signs was more critical than whether the sign had arrows or not. The study found that occupants were more likely to exit a building quickly and safely when exit signs were placed at eye level and were clearly visible.
These Factors Make a Difference
When selecting exit signs, it is essential to consider several factors beyond whether or not they have arrows. The color, size, and font of the sign can all impact its effectiveness.
Color
The color of the exit sign can have a significant impact on its effectiveness. The most commonly used colors for exit signs are green and red. Green is often used to indicate an exit or a safe location, while red is typically used to indicate danger or an emergency situation.
Size
The size of the exit sign is also an important consideration. The sign should be easily visible from a distance and should be proportional to the space in which it is located. The size of the sign should also be appropriate for the number of occupants in the building. The larger the building, the larger the sign should be.
Font
The font on the exit sign should be clear and easy to read from a distance. The NFPA recommends using a sans-serif font, such as Arial or Helvetica, as they are easier to read than serif fonts. The height of the font should be at least 1 inch for every 40 feet of viewing distance.
Illumination
The NFPA also recommends that exit signs be illuminated and visible from a distance of 100 feet. Illuminated exit signs are easier to see in low-light conditions or in the event of a power outage. The illumination source can be either electric or photoluminescent, which absorbs and stores light energy and then glows in the dark.
Placement
In addition to considering the color, size, font, and illumination of the exit sign, it is essential to place them in the correct locations for optimal effectiveness. Exit signs should be placed at eye level and should be clearly visible from any location in the room or building. It is also important to ensure that exit signs are not obstructed by any objects or other signs.
Questions on Exit Sign Options?
Both exit signs with arrows and plain exit signs are effective in guiding occupants to safety during an emergency.
