The following figures have been accrued though accomplishing the literature evaluate and summarized in this article for ULG fire designs. The figures are available in Added file 1 affiliated with this critique paper. The ventilation-managed situations didn't cause here any higher layer injury which was discernable, for that reason it won't be deemed here.
The characteristics of damage which have been claimed inside the literature to help investigators in pinpointing the cause of the fire pattern might be evaluated in this article.
