As a professional in the fire and life safety industry, we are constantly urging that a buildings fire protection systems be properly maintained. It is critical that a facilities passive fire as well as its active fire protection systems be working together and not one in place of the other. For instance, fire/smoke dampers, fire doors and firestopping help contain a fire and smoke to one location, while sprinkler systems and firefighters help put out the fire. So if we have these two systems working together, then why is there a continuous emphasis on the importance of photoluminescent egress path marking systems and exit signs in high rise facilities?
Well during a fire, smoke can quickly fill hallways and stairwells, making it dark and difficult to navigate. Since smoke rises, it can cause occupants to become disorientated and cloud their vision. Not to mention, trips and falls are more likely to occur during blackout or smoky conditions. Therefore, photoluminescent (PL) hallways, stairwells and exit signs are the best way to ensure that people will be able to find their way to safety during a fire.
Photoluminescent strips create an outline of steps, landings, handrails and any other obstacles that could potentially cause someone to have an accident, while exit signs mark the quickest way to evacuate. PL allows a building to have continuous visual support for up to 48 hours by producing sunlight or recycling existing electrical light. Not only does PL require no electricity, but it is made of quality material that is engineered to last the lifespan of your facility. More buildings today are being required by building codes to have photoluminescent egress path marking systems and exit signs installed, especially in high rise facilities. In fact, The International Building Code (IBC) and International Fire Code (IFC) requires that, “buildings having floors that occupy more than 75 feet above the lowest level of fire department vehicle must be provided with luminous egress path markings”.
Many commercial buildings, especially those in big cities like New York City, Los Angeles, and Chicago will have multiple floors filled with rooms and offices. Those occupying the upper floors are more likely to face smoky and blackout conditions in the event of a fire. So whether it be a hospitality, office building or even a healthcare facility, it is important to include photoluminescent egress path marking systems and exit signs in your building’s fire safety plan.
