Application Development of Smoke Leakage Test Apparatus for Door Sets in the Field

As global climate change intensifies, the frequency and severity of wildfires affecting communities worldwide are on the rise. Therefore, the issue of residential safety for people is becoming increasingly crucial. During a fire, smoke particles and toxic emissions could infiltrate the refuge space through gaps in doors, making it a primary risk factor for casualties. It is worth conducting in‐depth research and investigation on how to effectively utilize available tools and facilities to enhance the probability of survival while waiting for rescue behind closed doors. This study uses iron, aluminum, and wooden doors as experimental samples. Thirty participants conducted a total of 1,620 experiments using six different qualities of tape to investigate the impact of applying different layers of tape on improving door leakage and the time required for tape application. This study proposes that in situations when people are waiting for rescue in refuge spaces, the most efficient course of action would involve the fastest available tape. The rationale behind this is that while different types of tape may vary in their smoke‐shielding effectiveness, using three layers of tape can meet the leakage effectiveness standards, specifically less than 25 m3/hr at a differential pressure of 25 Pa.

This paper presents experimental research findings regarding the characteristics of fire safety equipment activation before and after a water-based fire suppression system is triggered. A group of typical indoor combustible materials (wood, linoleum, cardboard, paper) were used to construct Class A model fires in the experiments. The three most frequent fire causes were reproduced: the careless handling of fire (open flame), the unsafe operation of heating equipment and electrical short circuits. To identify the fire behavior, an automated system including fire (heat, smoke, flame) detectors, contact and non-contact temperature measurement instruments, a gas analysis system and video recording equipment was employed. Following the experiments, the most efficient (in terms of detection speed and reliability) combinations of technical equipment that are necessary and sufficient to identify all the combustion stages of substances and materials were determined. The efficient consumption of a fire-extinguishing agent was found to be possible when fire development stages were controlled. Guidelines on creating automated fire prevention systems in buildings were provided. These have the potential to significantly speed up compartment fire suppression.
