Background and Objectives: Fire is an inherent and permanent risk in the operating room and the prevention of it in the operating room require awareness of risks and effective communication between its staffs. Thus the purpose of this study is to determine the awareness and the practice of the operating room staff about fire prevention and to determine the effectiveness of safe...

Damage of the urban gas network due to an earthquake can cause much loss including fire-induced loss to infrastructure and loss due to interruption of gas service and repairing or replacing of network elements. In this paper, a new fire ignition model is proposed and applied to a conventional semi-probabilistic model for estimating various losses due to damage of an urban gas network in an eart...

Progressive collapse is defined as the spread of an initial failure from element to element, eventually resulting in the collapse of an entire structure or a disproportionately large part of it. The current progressive collapse analyses and design methods in guidelines and codes focus on the alternate load path method. This method is suitable especially in the case of blast-induced progressive ...

the newly found chah?r t?qi of mileh milehgeh is one of the fire-temples of the sassanian era that was built, like other fire-temples of that time, with pieces of rock and plaster. this chah?r t?qi which is the remaining core of a larger building consists of four stone walls of different sizes surrounded by a round corridor. inside this fire-temple there is a raised platform for setting up fire...

filling stations inside the urban environment are known as one of the existing and potential dangers in cities which according to their centralized fire load can be of high safety importance. tehran holds 101 active filling stations faced to extreme accidents and high explosion potentials. in this study, 59 out of 101 gas stations were investigated under the fire risk assessment implementation....

Effects of heat-transferring property of silver nanoparticles were evaluated on two solid woods of poplar and fir and in combination with Borax. Nanosilver and Borax were applied in pressure vessel using Rueping method. The size range of silver nanoparticles was 20-80 nm. Specimens of 150×130×9 mm were prepared and five fire-retarding properties were measured using a newly designed slide fire t...
