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. Photoluminescent tape can provide life-saving exit guidance to all residents, employees and tenants during an emergency evacuation by defining a space, border, or path so occupants can identify a safe route to an exit. Our safety-grade photoluminescent tape materials are inert, waterproof, non-toxic, non-radioactive and can be charged over and over again. A full charge providing 8 or more hours of luminance on DHi's AfterGlow® photoluminescent tape is achieved by exposing the tape material to:
3-4 minutes of ultraviolet (black) light, or
7-8 minutes of direct sunlight, or
21-23 minutes of fluorescent light, or
24-26 minutes of incandescent light.

Retroreflectivity Most materials absorb light or scatter it in random directions, where retroreflective materials reflect light directly back to the light source by passing light through spherical glass optical elements onto a mirror, or by using cube corner reflectors, in order to optimize reflection and create a high visibility surface. Today’s prismatic retroreflective sheeting can return as much as 60% of the light to the viewer. Retroreflective materials are often used by emergency personnel like police officers, paramedics, and firefighters to make them more visible in dark or low light situations. These materials are also commonly used for path marking or to improve safety where traffic control is important, and visibility of normal signs may be difficult.

Photoluminescence All DHi® photoluminescent signs (also known as glow-in-the-dark) sold through AfterGlow® Direct use strontium aluminate (SrAl), a much newer “Safety Grade” phosphor that is non-toxic and non-radioactive, and retain their ability to be recharged and glow brightly for many, many years. Typically, the luminance life span is 30+ years for safety-grade strontium aluminate (SrAl) materials and only 3-4 years for novelty-grade zinc sulfide (ZnS) materials. Ease of installation and reduced maintenance costs make photoluminescent signs a cost effective alternative to traditional illuminated signs.

Quick Overview
High Performance photoluminescent paint kit. This application is a two-part urethane paint system with all the materials necessary to paint 600 sq-in. A gravity feed HVLP spray gun with a 1.4-1.5 nozzle is recommended. Developed for the U.S. Navy and tested under the harshest of conditions.
High Performance, Photoluminescent Green, Aerospace Safety Paint
Photoluminescent Paint for Enhanced Propeller Visibility in Low-light Situations
Defense Holdings, Inc® (DHi) is now providing its patented AfterGlo® photoluminescent (glow in the dark) safety paint to the U.S. Navy, commercial aviators, domestic propeller manufacturers, and several military services outside the U.S. The aerospace and automotive-grade paint is applied to the tips of aircraft propeller blades, helicopter main and tail rotors, and other rotating objects to increase their visibility in low-light situations and thus help personnel to avoid injury or death from coming into contact with them. The initial application of this paint was on the Navy’s E-2C carrier aircraft to help save the lives of men and women who must work at night in the vicinity of rapidly spinning propeller blades and rotors on carrier flight decks where inadvertent contact can have deadly results. Potentially distracted by noisy, high-tempo flight operations, ground and flight personnel are inadvertently struck each year by propeller blades with inevitably tragic consequences. DHi’s solution combines a revolutionary, long-lasting, ultra-bright, non-radioactive photoluminescent paint to dramatically improve propeller blade. The application maximizes visibility, material adhesion, durability, wear-resistance and ease of installation without compromising propeller aerodynamic performance or aircraft detection. In battlefield conditions, greater visibility of propeller blades to ground personnel will help improve personal safety. Since the wavelength of the emitted light is outside of the range of IR Night Vision Goggles, use of the paint does not interfere with aircrew visibility or make the aircraft more vulnerable to hostile visual detection. The paint was developed under a Naval Air Systems Command (NAVAIR) contract as part of the Navy’s Small Business Innovation Research (SBIR) program. For authorized government buyers, this paint is also available through the DLA under NSN 6850-01-558-3002. Material Data Safety Sheets (MSDSs) can be found on Defense Holdings Inc.'s website
Photoluminescent Paint Usage on Helicopter Rotors
DHi’s photoluminescent paint application maximizes visibility, material adhesion, durability, wear-resistance and ease of installation without compromising rotor aerodynamic performance. At night, improvised landing zones (be it a vacant lot, road intersection, or some other cleared area) are an immediate attraction to people of all ages. Fire fighters, EMTs and police security personnel often have their hands full and even they can get distracted around the helicopter trying to keep order. People need sensory cues to warn them away from spinning rotor blades. Defense Holdings, Inc. demonstrates its AfterGlo® brand photoluminescent aviation safety paint on a Fairfax County, VA police helicopter.
