Emergency lighting is a vital part of any building's safety infrastructure. It ensures that people can safely evacuate in case of an emergency, even if the regular lighting fails. But how do you test emergency lighting, and when should you do it? In this blog, we will discuss the key aspects of emergency lighting, from how it works to how to properly test it.
Emergency lighting is designed to function when there is a power failure or when the regular lighting system stops working. This typically happens through an automatic switch that turns on the emergency lights as soon as there is a problem with the main lighting.
In modern systems, emergency lighting is often connected to a central battery or another power storage system. When the power goes out, the automatic sensor activates the emergency lights, ensuring that escape routes remain well-lit. This is crucial for allowing people to quickly find the exit, even in a dark or chaotic environment.
Testing emergency lighting is an important task that needs to be done regularly to ensure the system works effectively when needed. There are two main types of tests: the functional test and the battery test.
Functional Test: A functional test involves temporarily turning off the main power supply to check if the emergency lighting turns on when the normal lighting fails. This test should be performed at least once a month.
Battery Test: The battery test checks whether the batteries of the emergency lights have enough capacity to keep the lights on during a power outage. This can be done through a visual inspection or by running a test where the lights work off battery power for a set period. This test should be carried out at least once a year.
It is important to maintain a detailed logbook of all tests performed to demonstrate compliance with legal requirements for emergency lighting.
Emergency lighting has a clear purpose: to ensure the safety of people in a building during an emergency. The primary functions of emergency lighting are:
Marking Escape Routes: Emergency lighting helps people quickly and safely find the nearest exit. This is particularly important in large or complex buildings, where it can be difficult to navigate to the correct route without sufficient lighting.
Lighting Evacuation Routes: In an emergency, the number of people trying to evacuate may be large, potentially causing panic. By providing well-lit escape routes, it becomes easier for people to evacuate in an orderly and quick manner.
Safety Lighting: Emergency lighting ensures that there is always enough visibility, even when the regular lighting goes out. This is vital for preventing accidents and helping people move safely.
In summary, emergency lighting is a crucial part of any safe building. It is important to regularly check whether the system is functioning properly to avoid surprises in an emergency situation. By conducting the right tests and understanding the purpose of emergency lighting, you can ensure that everyone can safely and quickly evacuate the building during a critical situation.
