Hearing loss is a controversial occupational disease in fire fighters because exposure to hazardous levels of noise in this job is so variable and unpredictable. In this study, audiometric assessments were performed on 117 fire fighters to evaluate their hearing loss. The results showed that the average fire fighter has a characteristic noise-induced threshold shift, with maximum hearing loss o...
This study aimed to investigate the effects of the fire products treatments (heat, smoke and ash) on the density, species diversity, growth form and the life form of the soil seed bank in the semi-steppe rangelands of the Karsanak region in Chaharmahal and Bakhtiari Province. For this purpose, soil samples were collected from the studied region and fire products treatments were applied to them...
اثربخشی آتشسوزی تجویزشده، کنترل مکانیکی و شیمیایی بر مدیریت ورک (Rosa persica) در مراتع تخریبشده
Invasive plant control is a significant challenge for natural resources management. Rosa persica (Michx ex. Juss.) is one of the invasive species in Iran. It has been rapidly expanded to the areas where it has introduced. In the present study, we evaluated the effects of five treatments: 1) control, 2) fire, 3) cutting, 3) tilling, 4) chemical techniques (glyphsate application) in controlling ...
Background: Incident of fire within or outside the metro rail trains happened because of a number of reasons that cause catastrophic losses and shock to the community. This study aimed to assess the risk of fire in DC trains and subway lines in Tehran. Methods: For performing this research, after identification of fire hazards in metro trains through observation, interview techniques and revi...
Introduction: Being aware of the explosion, fire radius, and their damages, has an important role in accident prevention methods. Therefore, the aim of this study was modeling and evaluation of the consequences of propylene oxide spill in a petrochemical company. Material and Method: The QRA method including seven steps was used in this study. In the present study, in order to examine and...
background economic consequence analysis is vital for recognizing pipeline comprehensive risk analysis and emergency response planning. objectives the purpose of this study was to estimate economic loss due to fire and explosion in petrochemical feed and product pipelines. materials and methods the present study which performed on 47 pipelines of a petrochemical special zone, pertinent pipeline...
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...
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....
Introduction: Emergency situation is one of the influencing factors on human error. The aim of this research was purpose to evaluate human error in emergency situation of fire and explosion at the oil company warehouse in Hamadan city applying human error probability index (HEPI). . Material and Method: First, the scenario of emergency situation of those situation of fire and explosion at th...
