Fire Training Test Paper (B) Accreditation Number Score of Area under Unit Name 1. Fill in the blanks (1 point for each blank, 55 points in total) 1.Combustibles are substances that can react with (oxygen in the air) or other (oxidant) substances. 2.The higher the temperature of the fire source, the greater the energy, the greater the possibility of causing combustion. 3. Class B fires refer to (liquid) or meltable (solid) material fires.Such as gasoline, kerosene, asphalt, paraffin and other fires. 4.Especially serious fires.It refers to a fire that causes death of more than 30 people, serious injury of more than 100 people, or direct property loss of more than 100 million yuan. 5.The gaseous substance produced when a substance is burned is called smoke. 6.The flow of heat from (high temperature) region to (low temperature) region through material direct contact is called heat conduction. 7.Under the condition of coexistence of combustible substances with air, when it reaches a certain temperature, it can cause combustion when it comes into contact with (ignition source). The phenomenon that combustible substances can continue to burn after the ignition source leaves is called ignition. 8.According to the different mixing conditions of combustible gas and oxygen (air) before combustion, the combustion modes of gaseous substances are divided into (diffusion) combustion and (premixed) combustion. 9.The composition and structure of solid matter are different, and the combustion forms are also different. There are four main forms: evaporation combustion, surface combustion, decomposition combustion and smoldering combustion. 10.The fire resistance limit of building components refers to the period from the time when the components, fittings or structures are subjected to fire to the time when they lose stability, integrity or insulation under the standard fire resistance test conditions, which is generally expressed in hours. 11.Generally, the fire-resistant grade of buildings is divided into one, two, three and four grades.The first-grade refractory has the highest (high) performance and the fourth-grade refractory has the lowest (low) performance. 12.Fire resistance limit of fire doors at all levels: Class A fire door is (1.2) h, Class B fire door is (0.9) h, Class C fire door is (0.6) H. 13.Set up a separate outdoor (firewall) when the fire spacing is insufficient. 14.Steps on evacuation staircases and evacuation corridors should not be used (spiral staircases) or (fan-shaped steps). 15.When choosing the path of electric line, we should try our best to go short and straight from (power supply) point to (power supply) point, avoid twists and turns, and reduce crossover. 16.In order to ensure the normal work of indoor and outdoor lines, a comprehensive inspection should be carried out (every year). Where conditions permit, it can be carried out (half a year). 17.Common explosion-proof electrical equipment mainly includes explosion-proof type, Safety-increasing type and intrinsic safety type. 18.When flammable liquids are transported, the highest temperature in the carriage of a transport vehicle generally does not exceed (55)degrees C. 19.(Luminescence) Material refers to a substance other than the igniting substance that can heat itself without energy supply in contact with the air. 20.The vents of combustible gases and vapors lighter than air should be located in the upper part of indoor buildings and those of combustible gases heavier than air should be located in the lower part. 21.Controlling and eliminating the sources of fire are the most basic measures to prevent fire and explosion accidents in industrial enterprises. 22.Fire-retardant equipment is a kind of safety device to prevent (external) flame from entering equipment, pipes, containers with fire and explosion danger, or to prevent flame from spreading between equipment and pipes. 23.Hazardous chemicals vary in variety and nature. They should be stored in accordance with the principle of zoning and classification (separate warehousing and special storage), and in accordance with the principle of defining varieties, quantities, warehouses and personnel. 24.If the warehouse exceeds the maximum allowable area or the fire prevention interval is insufficient, additional (firewall) measures should be taken to remedy it. 25.(Gas Cutting) is a method of separating metals by heating metals to the burning point and burning them violently in the oxygen jet using the
