Natural gas (NG) is used as a home energy supply and, with or without ignition, is rarely misused to result in death. The authors report an unusual suicidal explosive death induced by NG. A huge explosion with resultant fire had blown out a bungalow, with destructive damage predominantly above the ground, resulting in only 1 exterior wall and the foundation still in place. The victim was transf...

The physical and chemical properties of an aerosol have a direct influence upon fire suppression mechanisms and extinguishing efficacy. These same properties are also basic determinants of aerosol inhalation toxicity. To evaluate the toxicity of an aerosol, it must first be determined if the aerosol can be inspired. Particles with a median aerodynamic diameter of 1-2 pm are capable ofpenetratin...

Fire protection is a basic safety issue for all categories of buildings. The criteria effective fire suppression and the characteristics extinguishing systems in insulated areas depend on combination factors. main influences include type combustible material, ambient temperature, spray extinguisher, air inflow outflow conditions, space geometry. This article analyzes most widely used fire-extin...

Fire protection strategies are designed and installed to perform specific functions. For example, a fire sprinkler system is expected to control or extinguish fires: To accomplish this, the system sprinklers must open, and the required amount of water to achieve control or extinguishment must be delivered to the fire location. A fire detection system is intended to provide sufficient early warn...

The use of hypoxic air venting system as fire protection is increasing and is sometimes used to replace traditional extinguishing systems. An oxygen level of 15% is generally used because a lower concentration could pose serious health risks. On the request of the Swedish Radiation Safety Authority, a literature review was conducted to determine advantages and challenges with the system and fur...

This report describes the case of a 43-yr-old male who developed reactive airways dysfunction syndrome after exposure to a high level of bromotrifluoromethane (CF3Br, Halon 1301), a fluorocarbon widely used in automatic fire extinguishing systems. The patient was a previously healthy, nonatopic male, who developed wheezing and intermittent and reversible obstructive ventilatory impairment start...
