wafer drying apparatus and fire-extinguishing method

A Study on a Method for Fire Suppression in a Central Area

Abstract This study was conducted to provide a method for fire suppression in a central area inside the roof of a wooden cultural property using a gas extinguishing apparatus which is used as one of fire suppression methods with view to preventing valuable wooden properties inherited from ancestors from being destructed by fire

TOPIC: Water as an Extinguishing Agent

These water resources also can be used with dry hydrants to refill mobile water tankers and transport water to fire sites or where feasible by use of mobile pumpers that can be used to pump water directly to fire sites Water is the least expensive of all the types of fire extinguishing agents currently available

Types of Fires and How to Extinguish Them

Jun 13 2018The heat absorption and the smothering effects of dry powder agents are suitable to extinguish a Class D fire Be aware that dry powder agents are entirely different from dry chemical agents The latter should never be used to put out a flame as it might intensify the fire Dry powder should always be used to extinguish a Class D fire

US20070158085A1

A fire extinguishing apparatus and method are proposed comprising: a container configured to receive and retain a fire extinguishing agent a pressure generator coupled to the container to have a generated pressure act upon the fire extinguishing agent to expel the fire extinguishing agent over an expel-exit of the container Due to a separator which is placed within the
