The Big Apple has some big differences in terms of what's required for emergency marking signs. Additional photoluminescent room number signs must be installed in NYC high-rise apartment buildings, ensuring that door numbers will still be visible if the power goes out during an emergency. For instance, if emergency personnel need to find a room or condo unit number in the dark, they'll be able to do so by looking at the illuminated room number signage. No matter what goes on to keep tenants in the dark in the big city, these photoluminescent will put a new light on any situation. |
