In which locations are floor furnaces prohibited from being installed?

Floor furnaces are designed for heating spaces by distributing warmth through airflow from beneath the floor. However, certain locations are not appropriate for their installation due to safety concerns, accessibility issues, and the potential interruption to foot traffic.

The correct choice pertains to aisles, auditoriums, and public halls, where foot traffic is heavy and unobstructed passage is essential. Installing floor furnaces in these areas could pose a safety hazard, as they could become tripping hazards or obstruct movement during emergencies. Additionally, these locations often require compliance with stringent building codes to ensure the safety and comfort of large groups of people.

Ultimately, by prohibiting floor furnaces in such high-traffic public spaces, safety measures help prevent accidents and ensure that heating systems are efficiently placed without hindering access or movement.
