Final answer:
False. Emergency lighting is designed to be independent of the utility company's power supply, instead relying on batteries or a generator. This ensures that exit signs and standby lighting remain operational during a power outage, which is crucial for safety.
Step-by-step explanation:
Emergency lighting does not depend on the power supply of the utility company; instead, it is designed to operate when the normal power supply fails. This often involves batteries or a generator as backup power sources. In fact, indicating false dependence on a utility company for emergency lighting aligns with the safety standards that require emergency systems to be operational during a power outage.
Understanding Emergency Lighting
When the normal power supply is interrupted due to a power outage or other failure, emergency lighting systems are crucial for providing illumination that can lead to safe evacuation from a building. This system gets activated automatically, highlighting exit paths and ensuring visibility in critical areas. The design of emergency lighting systems, which include exit signs and standby lighting, seeks to comply with both local regulations and building codes which specify the duration and level of lighting required during an emergency.
Answers to the reference questions include:
- Wood is an insulator, but lightning can travel through a tree to reach Earth, which makes the statement true.
- The high-voltage wires are held aloft by insulating connectors, but they are not wrapped in insulating material as they are designed for high-voltage transmission and are insulated by air, making the statement false.
- Improving lighting efficiency, such as switching to fluorescent or LED lighting, is an effective way to reduce electrical energy usage in both homes and businesses, decreasing costs and environmental impact.
Therefore, understanding the design and function of emergency lighting is essential for safety, and recognizing that they operate independently of the utility company's power supply is critical.
