Comparative study of radiant heat flux density transmission through firefighter protective clothing

Popis výsledku v původním jazyce

The main purpose of this research is to find out possibility of improvement in thermal protective performance (TPP) of fire fighter protective clothing (FFPC) when subjected to radiant heat flux density of 10 kW/m2 . Enlargement of TPP is related to the increase of time period when subjected to radiant heat flux density may provide surplus time for fire fighter to carry out duties without enduring harmful injuries. Each FFPC specimen constitutes outer shell, moisture barrier and thermal barrier. However, aerogel blanket was also utilized as substitute to thermal barrier because of its excellent thermal insulation property and inflammable nature. Preliminary testing was related to evaluating thermal resistance and thermal conductivity. Later experimentation involves exposure of multilayer FFPC specimen to radiant heat flux density of 10 kW/m2 . It was witnessed that those combinations in which aerogel blanket was utilized deliver higher thermal resistance i.e.0.1748 m2 K/W and improved TPP behavior in terms of transmitted heat flux density Qc (0.70 kW/m2 ) and percentage transmission factor (6.70%).
