Types of Symbol Exit

A symbol exit is a sign that indicates the location of emergency exits in a building. These signs are often required by law in commercial buildings to ensure the safety of employees and visitors. There are different types of exit signs, including the following;

  • Illuminated exit signs

    Illuminated exit signs have lights to make the symbols and text more visible. The lights used can be either LED or fluorescent. Illuminated signs are popular in areas with low light levels, as the lighting makes them easy to read. They are also popular in places where non-illuminated signs aren't visible due to distance or visibility. The lights in the sign are powered by a battery or electrical outlet.

  • Non-Illuminated exit signs

    Non-illuminated signs don't have lights and are usually made from materials like acrylic or metal. These signs rely on ambient lighting for visibility. They are popular in areas with enough light to make them readable. Non-illuminated signs are also a common choice for businesses looking to minimize costs.

  • Running Man exit sign

    This sign is based on the international symbol for emergency exits. It depicts a figure in motion, showing that people should leave quickly. The sign is easily recognizable and can be used in any country or language. It is popular in many buildings because of its clear message of quickly exiting the room.

  • Bilingual exit signs

    Bilingual signs show the symbol and text in more than one language. They are popular in multicultural societies or businesses with people who speak different languages. Bilingual signs ensure everyone understands the exit instruction, regardless of their primary language.

  • Photoluminescent exit signs

    These signs don't need electricity, as they are made from materials that absorb light. They glow in the dark during power outages or emergencies. Photoluminescent signs are eco-friendly and cost-effective, making them popular in green buildings. They are also used in areas where a backup power source isn't available.

  • Arrow exit signs

    Arrow exit signs show the direction of the nearest emergency exit. They are used if the main sign isn't clear or if there are multiple exit points. The signs can have the text ""EXIT"" or an arrow symbol pointing towards the emergency exit. Emergency lighting exit signs can be arrow signs. These signs are important in complex building layouts where clear directional guidance is needed.

Function and Feature of symbol exit

  • Exiting Programs:

    The primary purpose of the symbol is to terminate programs. When this command is executed, the program stops running, and control is returned to the operating system. The OS can then free up resources that were being used by the program, making them available for other tasks.

  • Exiting with Status:

    Another important aspect of the symbol is its ability to exit programs with a specific status code. This code is communicated to the operating system, which can then pass it along to any other programs that may have started this one. Typically, a status of 0 indicates that the program ran successfully, while any other number denotes an error.

  • Termination of Processes:

    Processes can be terminated in two different ways: normally or abnormally. A normal termination occurs when the process completes its task and exits voluntarily. On the other hand, an abnormal termination happens when the process is forced to exit, usually by an external command.

  • Exit System Calls:

    Within the realm of process termination, exit system calls play a crucial role. These calls allow a process to terminate itself and return control to the operating system. The exit system call is usually invoked when a program needs to end its execution.

  • Exit Status:

    The exit status of a program is a numerical value that indicates how the program ended. The operating system retrieves this status after the program has finished executing. The parent process can access the exit status by using the wait() system call. This status is usually stored in an integer variable.

  • Parent-Child Relationship:

    In the context of process termination, understanding the relationship between parent and child processes is crucial. The child process is the one that is created by the parent process. When a parent process terminates, it is said to have died. Its termination affects the child processes it has spawned.

How to Choose Symbol Exit

  • Consider the material and durability

    Materials are critical when selecting illuminated exit signs. Look for metal or high-impact, durable plastic signs. They offer good longevity and visibility. Consider the sign's location - indoor or outdoor. If outdoor, choose weather-resistant materials. For signs that will be installed in areas that have high levels of vandalism, choose materials that are resistant to damage or scratching.

  • Evaluate lighting options

    The lighting options for illuminated exit signs can include LED and fluorescent lighting. Although LED lights are more expensive when purchasing, they have lower maintenance costs and energy requirements. Their longevity and brightness make them a preferred option for illuminated exit signs. Consider the sign's visibility when making a choice. Choose lighting that offers optimum visibility, especially in low-light areas.

  • Assess battery backup capabilities

    Choosing an illuminated exit sign with battery backup capabilities is important. In instances where there is a power outage, the battery backup will ensure that the sign will continue to operate. Assess the battery backup runtime. Choose signs with batteries that can last for a number of hours. This will ensure the sign will be visible during emergencies. Consider the charging options when choosing a sign. Select signs with batteries that have fast charging capabilities.

  • Compliance with regulations

    When choosing illuminated exit signs, compliance with local and national regulations should be considered. Look at the regulations and standards that have been set concerning illuminated exit signs. Consider factors like letter height, visibility distance, and pictorial representation. Ensure that the signs being purchased are compliant with these regulations. This will avoid any legal issues that may arise. It will also ensure that the signs are effective in case of emergencies.

  • Assess installation and maintenance requirements

    When choosing illuminated exit signs, consider factors like installation and maintenance requirements. Some signs have complex installation procedures that require professional assistance. Others, however, have simple installation procedures that only require mounting. Choose signs whose maintenance requirements are minimal. Look for signs that have battery and lighting indicators. These will make it easy to monitor the sign's status.
