Download or read book Fire Toxicity written by A A Stec and published by Elsevier. This book was released on 2010-03-12 with total page 721 pages. Available in PDF, EPUB and Kindle. Book excerpt: Toxic fire effluents are responsible for the majority of fire deaths, and an increasing large majority of fire injuries, driven by the widespread and increasing use of synthetic polymers. Fire safety has focused on preventing ignition and reducing flame spread through reducing the rate of heat release, while neglecting the important issue of fire toxicity. This is the first reference work on fire toxicity and the only scientific publication on the subject in the last 15 years. Assessment of toxic effects of fires is increasingly being recognised as a key factor in the assessment of fire hazards. This book raises important issues including the types of toxic effluents that different fires produce, their physiological effects, methods for generation and assessment of fire toxicity, current and proposed regulations and approaches to modelling the toxic impact of fires. The contributors to Fire toxicity represent an international team of the leading experts in each aspect of this challenging and important field. This book provides an important reference work for professionals in the fire community, including fire fighters, fire investigators, regulators, fire safety engineers, and formulators of fire-safe materials. It will also prove invaluable to researchers in academia and industry. Investigates the controversial subject of toxic effluents as the cause of the majority of fire deaths and injuries Describes the different types of toxic effluents and the specific fires that they produce, their physiological effects and methods for generation Provides an overview of national and international fire safety regulations including current and proposed regulations such as a standardized framework for prediction of fire gas toxicity

Download or read book Flammability of Bio Based Rigid Polyurethane Foam as Sustainable Thermal Insulation Material written by Mikelis Kirpluks and published by . This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the biggest disadvantages of rigid polyurethane foams is its low thermal resistance, high flammability, and high smoke production when burning. Greatest advantage of this thermal insulation material is its low thermal conductivity, which at 20-25 mW/(m·K) is superior to other commercially available insulation materials. In recent years polyurethane materials from renewable resources have been widely studied. But their use on industrial scale was limited due to inconstant performance and relatively high price of raw materials. Different bio-based raw materials, such as rapeseed oil and tall oil, could provide abundant feedstock for PU foam production. Decrease of flammability of PU materials conventionally is achieved by addition of flame retardants, halogen-containing compounds, and phosphates. It can be considered that halogenated fire retardants could have several health hazards, such as volatile compound emission from materials and toxic gas release during burning process. Expandable graphite could be an answer to this flammability problem. This chapter describes development of bio-based rigid polyurethane foams and their flammability reduction using sustainable flame retardants. Different expandable graphite intumescent flame retardants provided significant flammability reduction while maintaining low thermal conductivity of insulation materials.

This book was released on 1973 with total page 143 pages. Available in PDF, EPUB and Kindle. Book excerpt: A study was conducted to determine the flammability characteristics and thermal degradation of urethane cellular plastics used in aircraft interiors. Model urethane polymers were prepared, and the effect of the chemical structure of isocyanates and ployols on performance during fire exposure were studied. A series of non-fire-retarded rigid-urethane foams was synthesized and evaluated to serve as the basis for further research directed toward the synthesis of fire-retarded systems. A series of fire- retarded rigid foams was synthesized incorp- orating reactive and non-reactive fire retardants in various concen-trations. The flammability characteristics of these cellular plastics were evaluated using test methods for the ease of ignition, flame propagation, fire endurance, smoke emission, and oxygen index as criteria. Based on the information obtained, a series of optimized rigid foams, which incorporated reactive and auxiliary fire retardants, was prepared and evaluated. Similar studies were carried out using formulations representing flexible urethane. (Author, modified-PL).
