This is a basic research on potential application of fire detection by measuring fire detection tendency of indoor air quality measurement factors. In this study, operation experiment using smoke detector sensitivity tester and paper fire experiment specified in UL 268 standards were conducted to evaluate the fire detection tendency of indoor air quality measurement factors. Based on the cross-substitution of values measured in the paper fire experiment, PM10 (excluding average) and HCHO (excluding average and maximum) for the indoor air quality meter (IAQ); PM1.0, PM2.5, and PM10 for IAQ S2; and CO (excluding the average and maximum) for combustion gas analyzers showed consistent tendency despite changes in the measured values for smoke generation under all experimental conditions. In particular, PM10 and CO are considered the most applicable fire detection factors among the factors measured in the experiment.

In this study, the characteristics of HFIX insulated wire sheaths contaminated by pollutants were examined. KS C IEC 60811-1-3 standard was followed in performing the water-resistance wire tests. Pollutants were selected, and the specimens were exposed to the pollutants for a maximum duration of four weeks. The maximum tensile load and the elongation rate were measured each week. As the period of pollution exposure increased, the maximum tensile load of the specimens decreased by 6.22% and 6.52% at room temperature and high temperature, respectively, and 19.94% for specimens coated with a rust-proof lubricant. The elongation rate also decreased rapidly, such that the reductions in the properties of the sheath were significant. From the analysis of the surfaces using a scanning microscope, as the contamination period increased, structural changes such as perforation, split, and melting occurred, and the mechanical properties of the specimens decreased. Therefore, it is necessary to develop and follow an inspection cycle and periodically carry out repairs to prevent the deterioration of insulated wires.

This study identifies the characteristics and influencing factors among survey respondents in response to domestic chemical terrorism by targeting firefighters sent to the front line of chemical accidents and chemical terrorism sites. It was carried out to present more efficient improvement measures for chemical terrorism. Regarding “Education and Training on Chemical Terrorism,” there were 3.01 points for “Education’s Information Transferability,” 2.65 points for “Satisfaction with Training Facilities,” 3.11 points for “Training (Theoretical) Effectiveness,” and 3.16 points for “Training (Practice) Effectiveness.” In total, 42.9% of the negative responses were regarding the satisfaction level of training facilities, demonstrating that domestic training facilities were the biggest problem in establishing current countermeasures. Rather than the training curriculum, it was judged that the training facilities were insufficient or absent, and it is necessary to secure and improve these facilities. Based on the survey results, training methods for team-level tactics and joint tactics between departments, hazard and risk assessment training for accident site commanders, and education on effective equipment utilization should be intensively conducted to secure safety and improve the response capabilities of field staff.
