fire behavior of rigid polyurethane foam and metal faced polyurethane sandwich panels and its fire hazard assessment
reaction to fire of fire-retarded rigid pur foams and two types of metal faced rigid polyurethane foam core sandwich panel was evaluated by using cone calorimeter test method. the tests were carried out in various radiative heat fluxes from 15 to 75 kw/m2. the radiation rate effect on reaction to fire parameters, including time to ignition (tti), peak of heat release rate (prhr), total heat rel...
متن کاملEffects of Fire Retardant Chemical and Fire Suppressant Foam on Shrub Steppe Vegetation in Northern Nevada
The objectives of this study were to determine the effects of fire retardant chemical (Phos-Chek G75-F*) and fire suppressant foam (Silv-Ex) application, alone and in combination with fire, on Great Basin shrub steppe vegetation. We measured growth, resprouting, flowering, and incidence of galling insects on Chrysothamnus viscidiflorus and Artemisia tridentata. These characteristics were not af...
متن کاملInvestigation of forest fire hazard areas in Golestan province based on fire risk system index (FRSI) using the technique (GIS)
Abstract Fire in natural resources is one of the crises that causes irreparable damage to ecosystems and the environment every year. The purpose of this research is to attempt to study areas of risk aversion and to prepare a map of forest fire hazard area by integrating topographic data and other additional information from a GIS system for Golestan province. In order to carry out this resear...
متن کاملIsolation and characterization of methicillin-resistant Staphylococcus aureus from fire stations in two northwest fire districts.
BACKGROUND Methicillin-resistant Staphylococcus aureus (MRSA) strains were isolated and characterized from environmental surfaces of two fire stations from two independent districts in the northwestern United States. After the first sampling and before the second sampling, education was provided, additional signage was added, and changes in disinfection protocols were put in place. Nasal carria...
متن کاملFight fire with fire
Since our hunter–gatherer ancestors began to develop agriculture more than 10,000 years ago, farmers have been battling with Nature to protect their cultivated plants against pests and diseases. Organisms from all kingdoms of life—from mammals and insects to bacteria, fungi and viruses—are attracted by the easy pickings that large fields of plants represent, and farmers have sought to contain t...
