National Civil Defence Cadet Corps: Fire Safety Quiz! Trivia Knowledge Test

Fire is caused by a combination of fuel, oxygen, and heat. Fuel provides the material that can burn, oxygen is necessary for the combustion process, and heat is required to initiate and sustain the fire. Without any of these three elements, a fire cannot occur.

Class A fires are caused by ordinary combustible materials such as wood, paper, and cloth. These materials are easily ignited and burn at a moderate rate. Class A fires can be extinguished using water or other common firefighting agents. Energized electrical equipment causes Class C fires, flammable/combustible liquids and gases cause Class B fires, and combustible metals such as magnesium cause Class D fires.

The nozzle is the part of a water-based extinguisher that directs the flow of water onto the fire. It is responsible for controlling the flow and dispersing the water in a specific pattern to effectively extinguish the flames. The nozzle is typically adjustable, allowing the user to adjust the spray pattern and reach of the water, making it a crucial component of the extinguisher.

A Class C fire is a fire involving energized electrical equipment. Electrical mains fire refers to a fire that occurs in the main electrical supply system. This type of fire can be caused by faulty wiring, overloaded circuits, or electrical equipment malfunctions. It is important to use the correct type of fire extinguisher, such as a CO2 or dry powder extinguisher, to safely extinguish a Class C fire without risking electrical shock.

The correct method of operating a fire extinguisher in chronological order is to first carry the extinguisher to the place on fire, then pull the safety pin out, aim the nozzle at the base of the fire, squeeze the discharge lever firmly, and finally sweep from side to side. This order ensures that the fire is targeted at its base and effectively extinguished by the extinguishing agent.

Fire is often described as a good servant because it can be controlled and used for various beneficial purposes such as cooking, heating, and generating electricity. However, fire can also be dangerous and destructive if it is not properly controlled or managed. Therefore, it can be considered a bad master as it has the potential to cause harm and destruction if not handled with caution and respect.

A fire extinguisher is designed to put out small fires effectively. It is specifically designed to combat fires in their early stages, before they have a chance to grow and become uncontrollable. By targeting small fires, fire extinguishers can quickly suppress flames and prevent them from spreading further, minimizing damage and protecting lives.

The fire triangle consists of three essential components required for a fire to occur: oxygen, heat, and fuel. Oxygen is necessary to support combustion, heat provides the energy to initiate and sustain the fire, and fuel is the material that undergoes combustion. The given answer, "Oxygen, heat, fuel," correctly lists these three components.

Standing facing the wind direction is not the correct safety procedure when using fire extinguishers. This is because standing facing the wind can cause the flames and smoke to blow towards the person, putting them at risk of burns or inhalation of toxic fumes. It is important to stand with the wind at your back, so that the extinguishing agent is directed towards the fire and not towards yourself.

The correct answer is "All of the above." When your clothes catch fire, dropping onto the floor helps to smother the flames and prevent them from spreading. Coming to a stop immediately is important to minimize the movement and airflow that can fuel the fire. Rolling your body across the floor helps to extinguish the flames by depriving them of oxygen. Therefore, all of these actions are recommended in order to effectively respond to a clothing fire.

The correct answer states that when trapped in a fire, the first step is to remain calm and not panic. Then, the person should move into an unaffected room to seek safety. They should cover the gap below the door to prevent smoke from entering the room. The next step is to signal for help, indicating that they are in need of assistance. Lastly, it advises against jumping out of the building, suggesting that other options should be explored before resorting to such a risky action.

The advantage of a hose reel is that it is lightweight, making it easier to transport and maneuver. It also offers ease of operation, allowing users to quickly and efficiently deploy and retract the hose. Additionally, a hose reel can be operated by a single person, eliminating the need for multiple individuals to handle the task. Therefore, the correct answer is "All of the above" as all the mentioned advantages apply to a hose reel.

The common types of fire extinguishers used are carbon dioxide extinguishers, dry powder extinguishers, and water-based extinguishers. These extinguishers are used for different types of fires. Carbon dioxide extinguishers are effective for electrical fires, dry powder extinguishers are suitable for flammable liquid fires, and water-based extinguishers are used for ordinary combustible material fires. Therefore, all of the above options are correct as they represent the common types of fire extinguishers used.

Fire extinguishers are not an example of a fire alarm and detector system. Fire alarm and detector systems are designed to detect and alert individuals to the presence of a fire, while fire extinguishers are devices used to suppress or extinguish fires once they have been detected. Fire extinguishers are a form of active fire protection, whereas fire alarm and detector systems are a form of passive fire protection.

Manual call points are required to be located at a height of 1.4 m. This height is specified to ensure that the call points are easily accessible and visible in case of an emergency. Placing them at a higher height would make them difficult to reach, while placing them at a lower height could make them prone to accidental activation or tampering. Therefore, a height of 1.4 m strikes a balance between accessibility and safety.

Automatic water sprinklers are designed to safeguard against all of the mentioned scenarios. They help prevent loss of life and property by quickly detecting and extinguishing fires. They also minimize interruption to business operations by controlling and suppressing fires before they spread. Additionally, sprinklers are designed to release water in a controlled manner, preventing excessive water damage that can occur when using a hose. Therefore, the correct answer is "all of the above."

The correct answer is "all of the above" because all the listed options correctly list out the parts of a fire extinguisher. The nozzle, safety pin, pressure gauge, discharge lever, discharge horn, and cylinder are all essential components of a fire extinguisher.

A water-based fire extinguisher should not be used for electrical fires, fires caused by flammable liquids, or fires caused by electrical equipment. This is because water conducts electricity and can cause electrocution if used on electrical fires. Additionally, water can spread flammable liquids and make the fire worse in the case of fires caused by flammable liquids. Therefore, it is not safe or effective to use a water-based fire extinguisher for any of these types of fires.

Fire is a process of combustion accompanied by the rapid release of heat and light in varying intensities. When fuel undergoes combustion, it reacts with oxygen in the air, releasing energy in the form of heat and light. The light produced during a fire is a result of the excited electrons in the fuel emitting photons as they return to their ground state. Therefore, light is a characteristic feature of fire.

Hose reel is suitable for extinguishing Class A fires. Class A fires involve ordinary combustible materials such as wood, paper, cloth, and plastics. Hose reels are designed to provide a steady flow of water to effectively cool and extinguish these types of fires. They are commonly found in residential and commercial buildings as a primary firefighting equipment.

The stage of fire known as "full development" refers to the point at which the fire has reached its peak intensity and is burning at its maximum level. At this stage, the fire has spread extensively, consuming all available fuel and producing large amounts of heat, flames, and smoke. It is a critical phase where the fire poses the greatest danger and is most difficult to control or extinguish.

A hose reel has a tubing fitted with a shut-off nozzle that is 30 meters long.

The correct answer is 15 m - 30 m. This range indicates that the hose reel can extend anywhere from 15 meters to 30 meters in length.

Foam is not a type of portable fire extinguisher because it is a type of fire suppressant that is used in conjunction with water. It is a mixture of water, foam concentrate, and air, and it is effective in extinguishing Class A and Class B fires. However, portable fire extinguishers typically use other types of suppressants such as water-based, carbon dioxide, or dry chemical powder, which are designed specifically for portable use. Therefore, foam is not considered a type of portable fire extinguisher.

All of the options listed (Deluge, Dry pipe, Wet pipe, and Pre-action) are types of sprinkler systems. Therefore, the correct answer is "All of the above."

The correct answer is black because CO2 extinguishers are typically painted black to differentiate them from other types of fire extinguishers. The black color helps users quickly identify and locate the CO2 extinguisher in case of an emergency. Additionally, the black color may also indicate that the extinguisher contains carbon dioxide, which is the agent used to suppress fires in CO2 extinguishers.

Call points, alarm sounders, and sprinkler systems are all common types of fire protection/detection systems. Call points are devices that can be manually activated to raise an alarm in the event of a fire. Alarm sounders are devices that produce a loud noise to alert occupants of a building to a fire. Sprinkler systems are automatic fire suppression systems that use water or other extinguishing agents to control or extinguish fires. Therefore, the correct answer is I, II & III.

A hose reel is a device that stores a fire hose and provides a quick and efficient way to extinguish fires. It allows for a continuous supply of water, which can help control and extinguish fires effectively. While fire extinguishers are also effective in fighting fires, a hose reel provides a larger volume of water and can be used for a longer duration. Prevention, on the other hand, refers to taking measures to avoid fires from occurring in the first place. Therefore, the best form of protection against fire is a hose reel, as it allows for immediate and sustained firefighting efforts.
