What is the purpose of lighting outlets in attics and underfloor spaces?

The purpose of lighting outlets in attics and underfloor spaces is primarily to ensure safety during servicing. These areas are often dark and can have obstructions, making it hazardous for individuals who need to service equipment, check insulation, or perform maintenance tasks. Proper lighting in these spaces significantly reduces the risk of accidents, such as trips and falls, and allows for better visibility to identify potential issues, such as water leaks or pest infestations.

While emergency lighting, aesthetic considerations, and compliance with ventilation codes may have their respective roles in building design and safety, the primary focus of lighting outlets in attics and underfloor areas is to provide a safe working environment for service personnel. Thus, the importance of safety during maintenance tasks underscores why this is the correct answer.
