The lateral spread of the sides of this pattern are caused by radiated heat from above and by the upward and outward movement of flames and hot fire gases when they encounter a horizontal surface such as a ceiling, or a she. The fire service investigatuon is relieved of the burden of extending hoses into the building from ground level to the fire location. This results in a pattern with the general shape of an hourglass. Fauquier Now.
Fire point the lowest temperature of a liquid in an open container at which vapors are evolved fast enough to support combustion. Flash Point - The minimum temperature at which any material gives off vapor in sufficient concentration to form an ignitable mixture with air. The varying heat levels can produce lines of demarcation which can be used to determine the characteristics and quantities, as well as to indicate the direction of fire spread. Overloading - The use of one or more electrical appliances or devices which draw or consume electrical current beyond the designed capacity of the existing electrical system.
Temperature is an intensity measurement, Fahrenheit, necessarily indicate flre of origin, mixes with air and burns. Arcing the production of sustained luminous electrical discharge between separated electrodes; an electric hazard that results when electrical current crosses the gap between 2 electrical conductors.
