NCDCC Fire Safety Proficiency Badge Written Assessment 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 the energy that initiates and sustains the reaction. Without any of these elements, fire cannot occur.

The given correct answer for this question is "nozzle". A nozzle is a part of a water-based extinguisher that controls the flow of water and directs it towards the fire. It is typically a small, narrow opening that helps in creating a focused stream of water to effectively extinguish the fire.

When trapped in a fire, it is important not to panic and avoid dashing through the fire. The correct order of steps is to first move into an unaffected room, then cover the gap below the door to prevent smoke from entering. Next, signal for help and avoid jumping out of the building. This sequence prioritizes finding a safe space and preventing smoke inhalation before seeking assistance.

The fire triangle is a model that explains the three elements necessary for a fire to occur. Oxygen is required to support combustion, heat is needed to raise the temperature of the fuel to its ignition point, and fuel is the material that can burn. Therefore, the correct answer is "Oxygen, heat, fuel."

The fire extinguisher is designed to put out small fires effectively. This is because small fires are more manageable and can be extinguished quickly before they spread and cause significant damage. Fire extinguishers are not typically designed to handle large-scale fires such as industrial fires or large bush fires, as these require specialized firefighting equipment and techniques. Additionally, explosions are a different type of emergency that may require specific measures beyond the capabilities of a fire extinguisher.

Fire is often used as a metaphor for power or energy. In this context, fire can be considered a "good servant" because it can be controlled and used for various purposes such as cooking, heating, and providing light. However, it can also be a "bad master" because if it gets out of control, it can cause destruction, harm, and even death. Therefore, the word that completes the sentence appropriately is "master".

Hose reel is suitable for extinguishing Class A fires. Class A fires involve common combustible materials such as wood, paper, cloth, and plastics. Hose reels are effective in extinguishing these fires as they provide a continuous supply of water or foam, which helps to cool down the burning materials and extinguish the fire.

Fire extinguishers are not an example of a fire alarm and detector system. While fire alarm and detector systems are designed to detect and alert individuals to the presence of a fire, fire extinguishers are devices used to suppress or extinguish fires once they have started. Fire extinguishers are a crucial part of fire safety equipment, but they do not fall under the category of fire alarm and detector systems.

A Class C fire involves energized electrical equipment or wiring. Electrical mains fire refers to a fire that occurs in the electrical system of a building, such as a fire in the electrical mains or electrical panels. Forest fire, oil tanker fire, and rubbish chute fire do not fall under Class C fires as they are not specifically related to electrical equipment.

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. It is important to use water or other appropriate extinguishing agents to control and extinguish Class A fires. Energized electrical equipment, flammable/combustible liquids and gases, and combustible metals such as magnesium are associated with different classes of fires and require different methods of suppression.

Manual call points are required to be located at a height of 1.4 m. This height is chosen for several reasons. Firstly, it ensures that the call point is easily accessible and visible to anyone in the vicinity. Secondly, it helps prevent accidental activation or tampering by children or unauthorized individuals. Lastly, placing the call point at this height allows for easy operation by adults without the need for excessive bending or stretching. Overall, locating manual call points at a height of 1.4 m ensures their effectiveness and accessibility in emergency situations.

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 fire and smoke to blow towards the person, putting them at risk of burns and inhalation of toxic fumes. It is important to stand with the wind at your back, so that the extinguishing agent can be directed towards the base of the fire, effectively suppressing it.

A hose reel has a 30 meters long tubing fitted with a shut-off nozzle. This means that the tubing attached to the hose reel is 30 meters in length. The shut-off nozzle allows the user to control the flow of water through the hose.

When your clothes catch fire, it is important to take immediate action to extinguish the flames and prevent further injury. Dropping onto the floor helps to smother the fire by depriving it of oxygen. Coming to a stop immediately reduces the spread of the fire and allows you to focus on extinguishing it. Rolling your body across the floor helps to smother the flames and can also help to cool down your body. Therefore, all of the above actions are necessary to effectively deal with a clothing fire.

When using the hose reel, it is important to ensure that the hose is not curled, keep the hose reel in your line of sight if you are assisting, and stand on the opposite side of the hose reel handler if you are assisting. However, standing tall when approaching the fire is not recommended. This is because standing tall can make you a bigger target for the fire and increase the risk of injury. It is advisable to crouch or stay low when approaching the fire to minimize exposure to heat and smoke.

The hose reel can extend to a length between 15 m and 30 m.

The correct answer is I & III. The reason for this is that using a water-based extinguisher for liquid and electrical fires can be dangerous and ineffective. It is important to use the correct type of extinguisher for the specific type of fire. Additionally, staying out of thick smoke areas is crucial for personal safety as smoke inhalation can be harmful. Standing facing the wind direction can help prevent the fire from spreading towards you and can also help with the effectiveness of using the extinguisher. Keeping as near to the fire as possible is not a safety precaution and can increase the risk of injury.

Water-based fire extinguishers 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 or spread the fire in these situations. It is important to use the correct type of fire extinguisher for each specific type of fire to ensure safety and effectiveness in extinguishing the fire.

To operate a fire extinguisher correctly, the first step is to carry the extinguisher to the place on fire. Then, pull the safety pin out to activate the extinguisher. Next, aim the nozzle at the base of the fire to ensure effective extinguishing. After that, squeeze the discharge lever firmly to release the extinguishing agent. Finally, sweep from side to side to cover the entire fire area and prevent re-ignition. This sequence of steps ensures a systematic and efficient approach to extinguishing a fire.

The correct answer is "all of the above". This means that all the options listed in the question correctly list out the parts of a fire extinguisher. The parts of a fire extinguisher include the nozzle, safety pin, pressure gauge, discharge lever, discharge horn, and cylinder.

The common types of fire extinguishers used are Carbon Dioxide Extinguisher, Dry Powder Extinguisher, and Water-based Extinguisher. These extinguishers are effective in combating different types of fires. Carbon Dioxide Extinguishers are suitable for electrical fires, Dry Powder Extinguishers are effective against flammable liquids and gases, and Water-based Extinguishers are used for ordinary combustible materials. Therefore, all of the above options are correct as they represent the common types of fire extinguishers used.

Foam is not a type of portable fire extinguisher because it is actually a type of agent used in fire extinguishers. Foam fire extinguishers are designed to extinguish fires involving flammable liquids, such as gasoline or oil. They work by forming a blanket of foam over the fuel, cutting off the oxygen supply and smothering the fire. Therefore, foam itself is not a type of fire extinguisher, but rather the agent used in a specific type of fire extinguisher.

Full development is the stage of fire when the fire is fully developed and burning near its maximum intensity. At this stage, the fire has reached its peak and is burning at its most intense level. This is when the fire has consumed most of the available fuel and is spreading rapidly, producing a large amount of heat and smoke. It is a critical stage where the fire can quickly spread and cause extensive damage if not controlled.

Fire is a process of combustion accompanied by the rapid release of heat and light in varying intensities.

The correct answer is black because CO2 extinguishers are typically painted black to distinguish them from other types of fire extinguishers. The black color helps people easily identify and locate the CO2 extinguisher in case of a fire emergency. Additionally, the black color is also used to indicate that the extinguisher contains carbon dioxide, which is the agent used to suppress fires in this type of extinguisher.

The advantage of a hose reel is that it offers lightness, making it easier to carry and maneuver. It also provides ease of operation, allowing for quick and efficient deployment of the hose. Additionally, a hose reel is designed for one-man operation, eliminating the need for multiple individuals to handle it. Therefore, all of the options mentioned in the question are advantages of a hose reel.

Automatic water sprinklers are designed to safeguard against various risks and potential damages. 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 can spread. Additionally, sprinklers are designed to release water in a controlled manner, reducing the risk of excessive water damage compared to using a hose. Therefore, the correct answer is "all of the above" as automatic water sprinklers provide comprehensive protection against multiple hazards.

The correct answer is "All of the above." This means that all of the options provided (I. Deluge, II. Dry pipe, III. Wet pipe, and IV. Pre-action) are types of sprinkler systems.

The correct answer is I, II & III. 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 to extinguish fires. Therefore, options I, II, and III are all correct.

A hose reel is the best form of protection against fire because it allows for quick and effective extinguishing of flames. It provides a continuous supply of water, which can be directed towards the fire source, helping to control and extinguish the fire. Fire extinguishers are also effective, but they may have limited capacity and need to be recharged or replaced after use. Prevention is important in fire safety, but it does not directly address the immediate need for extinguishing a fire. A cure is not a form of protection against fire.
