CO toxicity characteristics of flame retardants prepared by sol-gel method |
| 초록 |
This study was performed with to investigate the toxic gas emission characteristics of building interior materials that are the leading cause of fire deaths, especially focusing on CO. The CO emission was measured at 50 kW/m2 external heat flux with the three types of flame retardants and it was compared to the 50 ppm permissible exposure limit of OSHA. The flame retardants were synthesized with sodium silicate and slane compounds by sol-gel method. The maximum COmean (kg/kg) yield was obtained 0.041∼0.057 kg/kg. CO (ppm) peak value of all specimens were decreased by 26% to 27%. The time to CO (ppm) peak was decreased 92.6% up to 93.5% for all specimens compared with basic specimen. The CO toxicity of all specimens was observed to increase 1.62 times to 1.64 times compared with the permissible exposure limit of OSHA. |
