NightBright OCR-050 II Two-Pack
This pair of photoluminescent exit signs uses UV inks on aluminum to deliver high visibility in low light. UV-curable inks enhance color stability and legibility, while the aluminum substrate provides weather resistance. The OCR-050 II units are heat resistant and cold tolerant, making them suitable for exposed exterior walls or unheated spaces. The design supports clear visibility during evacuation and requires no electrical power, aligning with energy-saving safety solutions for industrial settings.
NightBright LDR-100 With Directional Arrows
The LDR-100 is a 100-foot photoluminescent exit sign featuring UV inks on aluminum. It complies with OSHA 29 CFR 1910.37(b)(7) and ASTM 2072 E for performance and durability while boasting seven-inch high letters and a one-inch stroke for legibility from a distance. The unit is designed for commercial application, with four predrilled holes for simple mounting. Its weatherproof performance makes it a versatile choice for varied environments, though it remains a passive, non-electrical sign solution.
LFI Swinging LED Exit Sign
The LFI Lights® Swinging LED Exit Sign (LEDsWRWBB) uses a vandal-proof hinged design with UL 924 listing. The red LED unit operates on 120-277 VAC and includes a battery backup option, ensuring emergency illumination during power loss. It is damp location rated and constructed from high-impact, V-0 flame-retardant thermoplastic housing. With a low energy draw (about 1.3 watts), long battery life, and a flexible mounting approach (wall, ceiling, or sloped ceilings with a canopy), this unit suits high-traffic or demanding environments requiring reliable visibility and durability.
NightBright OCR-050 12-Inch Sign
This 12-by-7.5-inch photoluminescent exit sign features UV inks on aluminum for enhanced durability and weather resistance. It follows OSHA standard 29 CFR 1910.37(b)(7) and uses a 6-inch letter height with a stroke of 0.75 inches. The eco-friendly aluminum substrate is 100% recyclable, aligning with sustainable facility requirements. It’s designed for reliable performance in mixed environments where power may be unreliable or unavailable, providing consistent visibility during emergencies.
Exit Sign Stickers, Glow in the Dark
ASSURED SIGNS offers glow-in-the-dark exit stickers in a 4-pack of 10-by-7-inch units. These self-adhesive vinyl signs are UV-protected, weatherproof, and designed for indoor or outdoor use without batteries. They enhance emergency readability by charging under daylight or artificial light, making them suitable for doors, walls, or windows in commercial spaces. While not a traditional sign, these stickers provide supplementary, low-cost visibility reinforcement in essential egress routes.
ADASigns.org Tamper-Proof Aluminum Sign
This aluminum brushed silver sign from ADASigns.org emphasizes tamper-proof mounting and heavy-duty installation. It is ADA-compliant and includes double-sided mounting tape, designed for long-term durability in busy commercial interiors such as offices and clinics. The product focuses on secure display and resistance to tampering, ensuring consistent exit labeling in environments where integrity and visibility are critical. It’s a practical option for signage that must withstand daily handling while remaining compliant with accessibility standards.
iSYFIX Exit Glow Sign, 2-Pack
The iSYFIX glow-in-the-dark exit signs use photoluminescent vinyl with an added UV-protective laminate for outdoor durability. The 2-pack is designed for indoor/outdoor use, with stand-alone charge requirements and extended visibility in low light, ensuring guidance towards exits during evacuations. They are weather-resistant and conform to typical signage needs for schools, offices, and warehouses, offering a cost-effective retrofit solution for non-electrical signage needs.
Buying Guide for Explosion-Proof Exit Signs
- Compliance and safety standards: Look for signs meeting OSHA 29 CFR 1910.37(b)(7) and ANSI Z535.1 for color and legibility. Consider ASTM classifications if you operate within industrial signage guidelines.
- Power source and reliability: Decide between photoluminescent (no power) and LED or electronic options with battery backup. In high-occupancy or critical areas, power-backed signs provide consistent illumination during outages.
- Material and durability: Aluminum bodies offer weather resistance and recyclability. For vandal-prone locations, choose vandal-proof hinged designs or tamper-resistant mounting.
- Visibility features: Letter height, stroke, and color contrast affect legibility from a distance. Directional arrows and predrilled mounting holes support precise egress guidance.
- Environmental suitability: Weatherproof and heat/cold tolerance are essential for exterior walls, loading docks, or unheated transit areas. Verify IP ratings if applicable.
- Maintenance and lifecycle: Photoluminescent signs require charging via light exposure; LED units require periodic battery checks. Consider replacement parts, warranties, and ease of installation in your space.
- Aesthetics and accessibility: ADA compliance ensures signage is accessible to all occupants. Choose neutral finishes (brushed aluminum or white backing) that blend with interiors while maintaining visibility.
- Installation considerations: Ensure mounting surfaces support required hardware, with proper clearance for illumination and legibility. Some models offer canopy kits or multiple orientation options for ceilings and walls.
- Cost and total cost of ownership: Compare upfront price, energy consumption, and maintenance costs. A higher upfront investment in durable, compliant signs can reduce long-term expenses and risk.
- Multi-sign systems: In large facilities, use a consistent signage set (same font, color, and material) to avoid confusion during an emergency. Directional arrows help guide occupants through complex layouts.
In summary, explosion-proof exit signs span photoluminescent and LED-based technology, with options designed for harsh environments and strict safety standards. The selections above provide a spectrum of durability, power options, and installation formats to fit industrial buildings, warehouses, and high-traffic facilities. Consider the interplay of compliance, environmental exposure, and maintenance needs when making a final choice to safeguard occupants during emergencies.
