Where is emergency lighting required to be installed?

• A. In all public areas
• B. Where a hazard could be caused by the failure of normal lighting
• C. In areas with loud machinery
• D. Only in exit routes

Answer: (B)

Emergency lighting is required to be installed where a hazard could be caused by the failure of normal lighting because it is essential to ensure safety in areas where visibility is critical for preventing accidents or injuries. In environments like mines or industrial settings, normal lighting might fail due to power outages or equipment malfunctions, which can lead to dangerous situations. Placing emergency lighting in these areas helps to guide personnel safely to exits or critical safety equipment, thus mitigating risks associated with low visibility or complete darkness.

While emergency lighting in public areas is beneficial for overall safety, it must be specifically focused on locations with the highest risk of hazard due to lighting failure. Additionally, although areas with loud machinery may present their own set of challenges, the installation of emergency lighting is not inherently linked to noise levels but rather to safety concerns in relation to visibility. Finally, requiring emergency lighting exclusively in exit routes would not address potential hazards that could arise in other critical locations, making it necessary to consider a broader scope for safety measures.
