New York City was the first legal jurisdiction to adopt as law the use of photoluminescent technology in the vertical exits of high rise facilities.The common terminology for this requirement is Stairwell Egress path marking however in photoluminescent terms is Safety Wayguidance system (SWG) or non-electrical, escape route lighting. JALITE is proud to haveplayed a big part of this development. JALITE was the leading manufacturer of photoluminescent safety products on the New York City task force that developed their reference standard for high rise, exit path markings (RS6-1) in accordance with their Local law 26. RS6-1 and which became the basis for revisions to the IBC, NFPA and Canadian building codes. JALITE is playing a major part in satisfying the needs of building owners and facilites management as we observe the progressive adoption of the IBC 2009 Code throughout the world.

Illuminant D daylight illuminants defined from 300-830nm, designated with a two digit subscript to describe Correlated Colour Temperature, e.g. D65 indicates 6500K, close to Illuminant C. Illumination luminous flux, usually of incident light. Units: lux or lumens per square metre. Infrared part of the electromagnet spectrum immediately less energetic than visible light, ranging from around 700 nanometres to 10 microns wavelength. Intersystem crossing transfer from one molecular angular momentum state to another by electron spin inversion. Principal of physical phosphorescence. Killing quenching. Light output quantum efficiency multiplied by amount of absorbed radiation. Lumen unit of light flux. One lumen equals the flux emitted into a solid angle of one steradian by a point source of one candela. Luminance brightness, usually of a surface, i.e. luminous intensity per unit area. unit: candelas per square metre, usually expressed in millicandelas per square metre. Luminescence emission of light from a substance unaccompanied by heat. Luminophor luminescent material. Luminous directional reflectance reflectance of a surface in given directions of illumination and view. The ratio of the brightness of a surface to the brightness that an ideally diffusing, perfectly white surface would have if illuminated in the same way. Units: none. Luminous intensity a fundamental unit derived from black body radiation at set conditions in a given direction. Unit: candela. Luminous efficiency (L) luminous flux emitted by a source, per unit of power consumed. Unit: lumens per Watt. Lux unit of illuminance, lumens per square metre. In imperial units, one footcandle is approximately 10 lux. Optically active a) luminescent, b) able to change the polarity of incident light during reflection. Phosphor a substance exhibiting the property of phosphorescence. Phosphorescence slower absorption and emission of photons where afterglow is usually apparent, involving electron spin inversion allowing absorbed energy to be trapped for a period before being released as photons.

Radiant efficiency ratio of emitted luminescent power to power absorbed from exciting radiation. Radioluminescence (RL) luminescence where the initial energy comes from radioactive decay, e.g. as with tritium. Products relying on RL are also called self emitters.

Strontium Aluminate a collective term for a group of crystalline phosphors derived from Strontium Oxide and Alumina (and silica) singally or doubly doped with rare earths Europium and Dysprosium. Thermoluminescence luminescence where heat energy triggers emission of photons from internal energy previously stored. Triboluminescence short lived luminescence caused by the violent breaking of chemical bonds, often associated with frictional forces. Ultraviolet part of the electromagnet spectrum immediately more energetic than visible light, ranging from approx. 100 nanometres (VUV) to 400 nanometres (UVA) wavelength. Up-conversion photoluminescent process converting lower energy incident light to higher energy emitted light. Also called anti-Stokes.

Fires or accidents in tunnels can be a major risk to human life and the effective identification of escape routes is paramount. Limited escape facilities and difficulties encountered by emergency services in gaining access to tunnel incidents calls for considered fire and emergency safety management. Tunnels and underground transport facilities are growing in terms of popularity and size in order to reduce rising traffic densities and congestion. As tunnel design evolves we need to identify the many hazards to be addressed: Increase in length of modern tunnels, unfamiliar territory - egress disorientation Transportation of hazardous materials - potential of contamination Higher fire loads due to growing increase in traffic volume coupled with higher load capacities – increasing fire risk Mechanical defects in motor vehicles – sources of ignition. Potential deterioration and failure/smoke logging of traditional escape route systems. Vehicle breakdown, road traffic accidents with inherently disorientated vehicle occupants. Fires within tunnels present an extremely high risk to occupants, the below table lists some of the international tragedies from recent years. The numbers highlight the horrific consequences of tunnel fire. Location Fatalities Location Fatalities Mont Blanc, France 39 Hokuriku Tunnel, Japan 34 Tauern Tunnel, Austria 12 Pecorile Tunnel, Italy 8 Vierzy Tunnel, France 108 Isola delle Femmine, Italy 5 Pfander Tunnel, Austria 3 Kaprun, Austria 155 Nihonzaka, Japan 7 St Gottard Tunnel, Switzerland 11 *Source: Alan Beard & Richard Carrel - The handbook of tunnel fire safety: 2005 With all the associated risks it is imperative that a fast and effective evacuation system is established to correctly identify the escape route educating evacuees to make an informed decision on egress. The serious outcome and risks associated with tunnel fires, emergency escape route systems are of the utmost importance in relation to life safety. With this in mind Jalite have developed an outstanding product raange for tunnels - engineered for life safety! Owing to the stringent requirements on constructional materials for use within tunnels, many of the common materials used in the photoluminescent industry are deemed unsuitable due to non compliance to the low smoke zero halogen requirements (LSZH). Jalite have strived to overcome the material restrictions and risen to the challenge meeting and exceeding requirements with the all new Jalite 316 LLL System and Jalite Polycarbonate Photoluminescent Escape Route Signs designed specifically for tunnels.
Safety signs produced to JALITE best practice have at least 10 key features that distinguish them from the local printer. All JALITE customer facing employees are expected to know the product line, the key features and the prevailing Standards in the field. JALITE is happy to explain to all clients the key features of a designed safety sign that is fit for purpose.
All the new tall buildings for commercial and industrial use in Seattle and major cities of Washington State USA will soon benefit from the same systems installed in New York City some 6 years ago. Washington State adopted Section 1024 of the revised IBC Building Code of 2009 to which all new buildings must comply within 2012. Of course, all existing buildings would clearly benefit from adopting the new code irrespective of any electrical systems installed and many forward thinking, "above minimum requirement" property owners will be considering improving their buildings for enhanced tenant safety.
