 All photoluminescent products sold by DHi use strontium aluminate or strontium silicate. These “Safety Grade” phosphors are non-toxic and non-radioactive, and retain their ability to be recharged and glow brightly for many, many years. Low Level Exit Path Markings (LLEPM) are a relatively new type of Life Safety Improvement and consist of a mix of exit path markings at traditional heights and other markings located near the floor where they wouldn’t be hidden by a layer of dense smoke descending from the ceiling and where they could be seen by someone crawling along the floor. They can provide life-saving exit guidance to all residents, employees and tenants during an emergency evacuation. In addition to our LLEPM systems, we offer a wide range of other signage ranging from our energy-saving, UL listed, PL exit signs, stairwell signage, emergency signage, custom signs, and many others. |
