Safe-T-Nose is North America's leader in luminous egress path marking technology.
Our mission is to provide the most complete, economical, and longest lasting luminous egress path marking system available. Not only are our solutions designed to save lives and prevent injuries, they are also designed with contractors in mind, making egress path markings fit your schedule and budget.
Leave No Doubt - This Way Out - Exit Safely
Building codes will help protect lives for new building construction. Our complete luminous egress path marking system for new construction, and existing buildings, exceed the requirements of the International Building Code and International Fire Code.
Photo-Glo - utilizes the same industrial grade solid polymer used in golf balls, imbedding photoluminescent pigment, the glow-in-the-dark material. This creates a durable material that is approximately 50% brighter than the code requires. Photo-Glo comes with and industry leading 25-year warranty.
Safe-T-Nose provides you ALL the products you need.

EXECUTION
EXAMINATION
Before installation, examine surfaces for appropriate application. Do not begin installation until substrates have been properly prepared. Commencement of work will imply acceptance of surfaces.
If substrate preparation is the responsibility of another installer, notify Architect of unsatisfactory preparation before proceeding.
PREPARATION
Clean surfaces to remove dirt, dust, grease, oil, loose material or other matter that may affect bonding of photoluminescent products.
Test substrates for compatibility before using other adhesives or mechanical fasteners.
Prepare surfaces using the methods recommended by the manufacturer for achieving the best result for the substrate under the project conditions.
INSTALLATION
Install in accordance with manufacturer's instructions and approved submittals.
Install products to be plumb, square and in alignment where required.
Follow supplied instructions.
** NOTE TO SPECIFIER ** Delete if not required.
PERIMETER MARKING INSTALLATION (STNF)
Thoroughly clean the surface area where the strip will be installed with a dry cloth and nonresidue cleaning compound to remove and loose particles and dirt. Surface must be dry and dust free.
Cut to length with scissors.
Peel the backing from the strip without touching the adhesive.
Place the strip and starting from one end to the other, firmly press the strip onto the installation surface. Be sure that the strip has full contact with the surface.
** NOTE TO SPECIFIER ** Delete if not required.
HANDRAIL STRIP INSTALLATION (STNH)
Thoroughly clean the surface area where the strip will be installed with a dry cloth and nonresidue cleaning compound to remove and loose particles and dirt. Surface must be dry and dust free.
Cut to length with scissors.
Peel the backing from the Handrail Strip without touching the adhesive.
Place the strip and starting from one end to the other, firmly press the strip onto the handrail.
Be sure that the strip has full contact with the railing.
** NOTE TO SPECIFIER ** Delete if not required.
NOSING INSTALLATION
** NOTE TO SPECIFIER ** Delete if not required.
STNP and STNC3 Installation:

Trowel joint at back of construction cover.
Remove the construction cover after concrete is fully dry and all painting and cleanup is complete.
** NOTE TO SPECIFIER ** Delete if not required.
STNR Installation:
Verify the surface is clean, dry, flat and smooth.
On concrete, use a leveling compound if necessary to provide a level/smooth surface.
Use dry cloth and non-residue cleaning compound to remove dirt and grime.
Use construction grade (water resistant) adhesive.
Recommended Adhesive: Bostik 1100FS or 70-03A.
If Adhesive is used: Apply continuous bead of adhesive, centered on underside of nosing.
Place and press nosing centered on front edge of tread.
Allow adhesive rated cure time before stair use.
** NOTE TO SPECIFIER ** Delete if not required.
STNC Installation:
Verify the wet concrete surface is smooth and level.
Push the nosing, centered, front edge of riser, into the wet concrete with the plastic isolator embedded in the concrete.
Top of construction cover shall be level with the surface of the concrete.
Trowel joint at back of construction cover.
Remove the construction cover after concrete is dry fully and all painting and cleanup is complete.
Do not allow heavy objects to come in contact with installed products.
Keep construction covers on as long as practical to protect nosings during construction.
INSTALLATION INSPECTION:
Check regularly for loose nosing's or damaged components. Replace damaged components, repair delaminated Photo-Glo components as required. Tighten loose fasteners as needed.
PHOTO-GLO CHARGE INSTRUCTION:
Minimum of 1 foot candle (11 Lux) of fluorescent, incandescent or light emitting diode (LED) for 60 Minutes is required to charge Photo-Glo.
Control of lighting restricted to authorized personnel. Reliable external illumination is required at all times during building occupancy.
Do not use Photo-Glo where the ambient illumination level is less than 1 foot candle (11 Lux).
CLEANING
Cleaning: Clean Work of this Section prior to Substantial Completion.
Establish a regular inspection schedule for the photoluminescent components and clean them as needed to prevent dirt, etc. from inhibiting the performance of the components. Safe-T-Nose, Inc. recommends inspection at least annually or after any particularly heavy use. Perform inspections in accordance with applicable local and national code requirements.
Photoluminescent components attached to floor assemblies may be cleaned by mopping, using high-pressure water (NO STEAM CLEANING) or wiping with a clean damp cloth. Use mild detergents to clean the photoluminescent components, if necessary. Mild dish washing detergents or laundry detergents are recommended. Do not use highly alkaline detergents, those having a ph greater than 8, or acidic cleaners, those having a ph less than 5. Do not use abrasive cleaners. Photoluminescent components on walls or other assemblies or components may be cleaned using clean water and a clean sponge or a clean cotton cloth. Rinse after applying detergent solution. Wipe with a clean cotton cloth to dry.
Regular Maintenance:
Inspect exit path markings, obstacle markings and photoluminescent stair nosing for damaged components and to ensure that photoluminescent components remain properly attached to their substrate and that no loosening of anchors or delamination of photoluminescent components has occurred.
Replace damaged components. Repair delaminated photoluminescent components. Contact the factory for repair recommendations. Delaminated photoluminescent components in stair nosings can result in trip hazard.
PROTECTION
Protect installed products until completion of project.
Touch-up, repair or replace damaged products before Substantial Completion.
