A Study on the Availability of the Toilet Exhaust Port in Apartment Households for Smoke Exhaust

Abstract

This paper suggests a system to reduce suffocation casualties in apartment households by smoke exhaust using the toilet exhaust port adjacent to the outdoor. The opening/closing method of the fire damper attached to the existing systems takes the form “CLOSED” to prevent flame and smoke diffusion, but the method used in the proposed system is contradictory to this method. The results of the legal review of the smoke exhaust system depends on the conformance of the damper performance to legal requirements. Hence, the proposed system can be applied if the damper performance conforms to the legal requirements and the air velocity in the pipe shaft is within the legal velocity limit. However, the exhaust rate of the natural exhaust system must be considered.
