Safety

Safety in public buildings and at workplaces has become an increasing focus of attention in recent years. Fires in public buildings and underground stations have drawn attention to the necessity for an escape route system that works even in the worst circumstances, such as no electricity, smoke and panic.
Lumilux® N and SN products are used for safety-way-guidance systems that meet international standards. These phosphorescent materials with long afterglow properties are integrated in specially designed components of standardized silk screen printed safety signs, dispersion paints, plastics and resins. Under regular illumination, these signs are completely unobtrusive and blend into building structures. Under darkness due to power failure, they glow strongly and guide people’s way. These pigments can be found in safety-passage way-and exit guidance systems in public buildings, hospitals, factories, stations and tunnels, as well as on trains, airplanes and ships.

Pigments for safety applications must meet the minimum afterglow requirements of international standards. The relevant metric for these requirements is DIN 67510-1 regulation that is internationally recognized as the standard for testing. In North America, safety sign standards are set up in the Emergency Lighting and Power Equipment as published by UL 924 (Underwriters Laboratories) Specification. For safety applications, Honeywell offers zinc sulfide-based Lumilux Green N-grades and the new, much brighter alkaline earth aluminates Lumilux Green SN-grades. Both types of pigments can be used for phosphorescent safety products, such as:

	Afterglowing guidance lines for wall, floor and exit door markings
	Direction signs
	Arrows, footprints and dots for floor markings
	Internationally and nationally standardized safety signs
	Safety and rescue equipment, such as fire extinguishers, first aid kits and fire hoses
	Afterglow markings on staircases to mark the steps
	Handrail markings
	Door handles and opening device markers

The relevant metrics for these requirements are technical standards and codes, for instance:

	DIN 67510-1, parts-1, 2, 3, 4 (Photoluminescent pigments and products)
	UL 924, Underwrite Laboratories, Standard for Emergency Lighting and Power Equipment
	UL 1994, Luminous Egress Path Marking Systems
	NFPA 101. Life Safety Code (allows photoluminescent high-performance exit signs in high-location installations if they are listed in compliance with UL 924
	APTA SS-PS-004, Standard for Low Location Exit Path Marking
	ISO/DIS 16069, Graphical Symbols, Safety signs, Safety way guidance systems

Honeywell Specialty Materials can produce customized luminescent pigments to customers specifications.
