Fire Safety Rules Quiz!

Explanation
Cloth is considered a Class A fire because it is a common combustible material that can easily ignite and sustain a fire. Class A fires involve ordinary combustible materials such as wood, paper, cloth, and plastics. These fires typically leave behind ash and char after burning. Electrical, metal, and flammable liquid fires are classified differently and fall under Class C, Class D, and Class B respectively.

Explanation
Gasoline is classified as a Class B fire because it is a flammable liquid. Class B fires involve flammable liquids or gases, such as gasoline, oil, propane, or natural gas. These fires can be extinguished using fire extinguishers specifically designed for flammable liquid fires, such as foam or carbon dioxide extinguishers.

Explanation
Class A fires involve ordinary combustible materials such as cloth, wood, and paper. Class B fires involve flammable liquids and gases like gasoline and propane. Class C fires involve electrical equipment. The answer "trash, flammable liquid, electrical" correctly identifies the materials involved in Class A, B, and C fires.

Explanation
The correct answer is "Yes" because Class D fires involve combustible metals and combustible metal alloys. These types of fires are caused by substances such as magnesium, titanium, sodium, potassium, and lithium, which can ignite and burn at high temperatures. It is important to use specialized extinguishing agents, such as dry powder, to effectively extinguish Class D fires and prevent further damage.

Explanation
Yes, a Class K fire cooking media includes vegetable or animal oils and fats. These types of fires are commonly found in commercial kitchens where these cooking oils and fats are used. Class K fires require a specific type of fire extinguisher designed to effectively suppress and extinguish these types of fires.

Explanation
Class A fires typically involve common combustible materials such as wood, paper, and textiles. Class B fires, on the other hand, involve flammable liquids such as gasoline, oil, and alcohol. Therefore, both Class A and Class B fires can involve wood and flammable liquids, making the answer "Yes" correct.

Explanation
Class B fires involve flammable liquids such as gasoline, oil, and grease, while Class C fires involve energized electrical equipment. Wood and metal are not specifically mentioned in the question, so it cannot be concluded that Class B and C fires involve them. Therefore, the correct answer is "No."

Explanation
Fire extinguishers should be checked regularly, but not necessarily on a weekly basis. The frequency of checking fire extinguishers depends on various factors such as the type of extinguisher, its location, and the specific regulations or guidelines set by local authorities or fire safety organizations. While weekly checks may be excessive, it is still important to ensure that fire extinguishers are inspected and maintained at regular intervals to ensure their effectiveness in case of an emergency.

Explanation
Fire extinguishers must be maintained at least once a year by an FDNY approved company and a W-96 Certificate of Fitness holder. This ensures that the fire extinguishers are in proper working condition and ready to be used in case of a fire emergency. Regular maintenance helps to identify any issues or malfunctions with the extinguishers and allows for necessary repairs or replacements to be made. By conducting annual maintenance, the FDNY and W-96 Certificate of Fitness holder ensure the safety and effectiveness of fire extinguishers in various locations.

Explanation
Combustible materials are substances that can catch fire and burn easily. Paper is a combustible material because it is made from plant fibers that can be easily ignited and sustain a fire. Iron, on the other hand, is not combustible as it requires extremely high temperatures to ignite. Propane gas and oil are also combustible materials as they can easily catch fire and burn.

Explanation
A combustible liquid is a substance that can easily catch fire and burn when exposed to an ignition source. Gasoline is a prime example of a combustible liquid as it has a low flash point and can ignite easily. It is commonly used as a fuel for vehicles and machinery due to its ability to burn efficiently. Iron and zinc are not combustible liquids, as they are solid metals and do not have the properties necessary to sustain combustion.

Explanation
P.A.S.S. stands for Press, aim, squeeze, sweep. This acronym is commonly used to remember the steps for operating a fire extinguisher. "Press" refers to pressing the handle to activate the extinguisher, "aim" means directing the nozzle at the base of the fire, "squeeze" is for squeezing the handle to release the extinguishing agent, and "sweep" indicates moving the nozzle from side to side to cover the entire fire area.

Explanation
To extinguish a fire, it is important to aim at the base. This is because the base of the fire is where the fuel source is located. By aiming at the base, you can cut off the fire's oxygen supply and prevent it from spreading further. Aiming at the center, top, or side may not be effective as it does not directly target the fuel source.

Explanation
A fireguard does not approach a fire from a downwind direction because doing so would put them at risk of being engulfed by the flames and smoke. Approaching a fire from the downwind side would expose them to the full force of the fire and make it difficult to control or extinguish the fire effectively. Therefore, it is safer for a fireguard to approach a fire from an upwind direction, where the wind is blowing away from the fire, reducing the risk of being caught in the fire's path.

Explanation
In the event of an emergency, it is crucial to have immediate access to shut off the gas supply. By having the oxygen and fuel gas container valves accessible to the torch operator or fire guard, they can quickly and efficiently shut off the gas, preventing further damage or danger. This ensures the safety of everyone involved and allows for swift action to be taken in emergency situations.

Explanation
The statement suggests that Fireguard should regularly inspect all areas of the job site every hour from 4 pm to midnight each day. This is important to ensure the safety and security of the job site, as it allows Fireguard to identify and address any potential fire hazards or risks in a timely manner. Regular inspections also help in detecting any unauthorized activities or violations of safety protocols. Therefore, it is crucial for Fireguard to walk all areas of the job site every hour during the specified time period.

Explanation
In the event of a fire, the fire guard is responsible for taking immediate action to extinguish the fire and ensure the safety of the construction site. They should also notify the Construction site Fire Safety Manager and the owner of the premise, but it is not their sole responsibility. Other individuals on the construction site, such as workers or supervisors, may also have the authority to notify these individuals. Therefore, the statement that the fire guard must call the Construction site Fire Safety Manager and owner of the premise is false.
