    p.295. What are the Fire Types?

     

    C.295.

    >>>>> Class A fires: Solid material fires. It can be extinguished by cooling and removal of the combustible material.

    >>>>> Class B fires: Combustible liquids are the fires they cause. It can be extinguished by cooling (water in fog) and suffocation (carbon dioxide, foam and dry chemical powder).

    >>>>> Class C fires: These are fires caused by the combustion of various flammable gases such as liquid petroleum gas, air gas, hydrogen. Dry chemical powder can be quenched using halon 1301 and halon 1211. We can also include fires of electrical machinery and sensitive equipment in this class. The fires caused by the combustion of flammable light metals and alloys (such as magnesium, lithium, sodium, cerium) in C class fires draw attention. Dry chemical powders extinguish these fires. It does not evaluate fires caused by the burning of electrical equipment in a separate class. It is included in class C fires. Such fires should be intervened by cutting the electric current and dry chemical powder should be used.

     

    Q.296. Explain Class C fire and how is it extinguished?

     

    C.296. Class C fires: These are fires caused by the combustion of various flammable gases such as liquid petroleum gas, air gas, hydrogen. Dry chemical powder can be quenched using halon 1301 and halon 1211. We can also include fires of electrical machinery and sensitive equipment in this class. The fires caused by the combustion of flammable light metals and alloys (such as magnesium, lithium, sodium, cerium) in C class fires draw attention. Dry chemical powders extinguish these fires. It does not evaluate fires caused by the burning of electrical equipment in a separate class. It is included in class C fires. Such fires should be intervened by cutting off the electric current and dry chemical powder should be used.

     

    S.297. Describe a Class B fire and how is it extinguished?

     

    C.297. Class B fires: Combustible liquids are the fires they cause. It can be extinguished by cooling (water in fog) and suffocation (carbon dioxide, foam and dry chemical powder).

     

    S.298. Describe a Class A fire and how is it extinguished?

     

    C.298. Class A fires: Solid material fires. It can be extinguished by cooling and removal of the combustible material.

     

    Q.299. Please explain the failure to take protective measures, which is the cause of fire?

     

    C.299. Failure to take protective measures: One of the main causes of fire is failure to take precautions against fire. Generally, fire occurs when electrical contacts, heating systems, LPG cylinders (cylinder gases used in homes), explosive-flammable materials are not adequately protected. The reason for most of the fires in residential and workplace areas, especially in large residential areas, is the misuse of electricity and LPG cylinders. The fact that the electrical energy components are not made according to the technical conditions is another reason for the fire. However, there will be a great reduction in fire disasters if necessary precautions are taken for heating chimneys, chimneys and flammable-explosive materials in central heating and stove heating methods.

     

    S.300. Explain the ignorance that caused the fire?

     

    C.300. Ignorance: Not knowing what precautions and how to take precautions against fire and not getting enough training in this regard are important causes of fire. Not knowing the correct use of electrical tools, incorrectly placing the stove and heating systems, placing easily flammable items in the attic and on the roof invites fire. Preventing the occurrence of fire and knowing how to extinguish a fire goes through education and information. For this reason, it is necessary to learn the first interventions in extinguishing the fire as well as learning to prevent the fire.

     

    S.301. What are the causes of fire?

     

    C.301.

    A- Failure to take protective measures

    B- Ignorance

    C- Neglect

    C- accidents

    D- Sabotage

    E- Splash

    F-Natural events

     

    P.302. Explain the accidents caused by fire?

     

    C.302. Accidents: Some of the unintentional events (such as the explosion of the heating boiler, electrical contact) cause fire. In all spontaneous events, not taking adequate precautions at the beginning can be effective, and we can see that ignorance also plays a role. Basically, without these, there are also fires caused by accidents.

     

    S.303. Explain the sabotage that caused the fire?

     

    C.303. Sabotage: Although necessary precautions are taken against fire, some people may deliberately burn buildings and facilities belonging to individuals and communities for various purposes and gain, causing loss of life and property.

     

    S.304. Explain the splash that caused the fire?

     

    C.304. Vault: A controlled or uncontrolled fire can reach larger dimensions by splashing, spreading or flashing as a result of negligence or ignorance. Therefore, we need to be careful about such events.

     

    S.305. Explain natural events that cause fire?

     

    C.305. Natural events: In windy weather, dry branches rubbing against each other or lightning strikes, etc. Fire may occur as a result of natural events such as

     

    S.306. Explain the negligence that caused the fire?

     

    C.306. Neglect: It is not enough to have knowledge about fire. Negligence such as a match or cigarette butt that is thrown out without extinguishing, the LPG tube that we forget to turn off (the gas cylinder used at home), the stove whose fire is not extinguished, the iron whose plug is left in the socket can cause big fires.

     

    S.307. What are the methods used in fire extinguishing?

     

    C.307.

    A-Extinguishing by Cooling

    B-Cut the Air

     

    S.308.How to extinguish a fire by cooling?

     

    C.308.

    A-Water cooling: It is the most used one among the principles of quenching by cooling. The favorable physical and chemical properties of water are the most important factors in suffocating the flammable substance (reducing oxygen as a result of throwing the burning object into the water) and extinguishing the fire by taking heat from the flammable substance. Water can be sent to the fire place in mass as well as by spray lances.

    B-Dispersing the combustible material: By dispersing the burning material, the high heat that causes the fire is divided, the split heat decreases and the fire gradually goes out. In fuel oil fires, this type of extinguishing is not applied as it will cause the fire to spread.

    C- Strong blowing: Strongly blown air on the burning material causes the flame to extinguish and the temperature of the burning material to decrease. With this type of (by cooling) extinguishing principle, success can be achieved in initial fires. In fires that have grown or have reached certain dimensions, strong blowing will cause the fire to grow as it will provide more oxygen to the fire. For this reason, such extinguishing is not used on large fires.

     

    p.309. How is the water cooling method done in extinguishing the fire by cooling?

     

    C.309. Cooling with water: It is the most used one among the principles of quenching by cooling. The favorable physical and chemical properties of water are the most important factors in suffocating the flammable substance (reducing oxygen as a result of throwing the burning object into the water) and extinguishing the fire by taking heat from the flammable substance. Water can be sent to the fire place in mass as well as by spray lances.
