Fire Safety Quiz: MCQ Trivia! Test

When heat, fuel, and oxygen combine, they create the necessary conditions for a fire to occur. Heat provides the initial energy to start the reaction, fuel acts as the combustible material, and oxygen acts as the oxidizing agent. Without any one of these components, a fire cannot be sustained. Therefore, it is true that the chemical reaction of heat, fuel, and oxygen will cause a fire.

The PASS procedure is an acronym that stands for Pull the pin, Aim at the base of the fire, Squeeze the lever, and Sweep from side to side. This procedure is commonly recommended for using a fire extinguisher effectively. Therefore, the statement "When using a fire extinguisher you should use the PASS procedure" is true.

The statement "Fires in the workplace cause more than 2 billion dollars in property damage each year" is true. This means that fires occurring in workplaces result in property damage worth more than 2 billion dollars annually.

Having smoke or fire alarms in all areas of the workplace is necessary for ensuring the safety of employees and preventing potential hazards. These alarms can quickly detect the presence of smoke or fire, allowing for immediate evacuation and prompt response from emergency services. By having alarms installed throughout the workplace, any potential fire or smoke-related incidents can be detected early, giving employees ample time to evacuate safely and minimizing the risk of injuries or fatalities. Therefore, it is crucial to have smoke or fire alarms in all areas of the workplace to maintain a safe working environment.

Gasoline, paints, and solvents all have the potential to fuel a fire. Gasoline is highly flammable and can easily ignite when exposed to a spark or flame. Paints often contain volatile substances that can combust when heated. Solvents, such as alcohol or acetone, are also highly flammable and can contribute to the spread and intensity of a fire. Therefore, all of these chemicals have the potential to fuel a fire.

Class A fires are the most common type of fires because they involve ordinary combustible materials such as wood, paper, cloth, and plastics. These materials are commonly found in homes, offices, and other everyday environments, making Class A fires more likely to occur compared to fires involving other types of materials.

This statement is false because not all fire extinguishers are designed to work on all types of fires. Different types of fires require different types of extinguishing agents. For example, water extinguishers are effective on Class A fires (involving ordinary combustible materials like wood or paper), but they should not be used on Class B fires (involving flammable liquids like gasoline or oil) as it can spread the fire. Similarly, CO2 extinguishers are suitable for electrical fires, but they may not be effective on other types of fires. Therefore, it is important to use the appropriate fire extinguisher based on the type of fire.

The statement states that each year in the United States, 70-80,000 workplaces experience a fire. This implies that there is a significant number of workplace fires occurring annually in the country. Therefore, the answer "True" is correct as it aligns with the information provided in the statement.

Exits should never be partially blocked, even if they are visible. It is crucial to maintain clear and unobstructed exit paths to ensure the safety of individuals in case of an emergency. Partially blocked exits can impede the evacuation process and potentially lead to injuries or fatalities. Therefore, the statement that exits may be partially blocked as long as they are visible is false.

Monthly inspections should be performed on fire extinguishers to ensure that they are in proper working condition and ready to be used in case of a fire emergency. Regular inspections help identify any potential issues or damages to the extinguisher, such as leaks or expired contents, and allow for timely maintenance or replacement. This practice is essential for maintaining the effectiveness and reliability of fire extinguishers, thereby enhancing fire safety measures in a given environment.

Carbon Dioxide based fire extinguishers remove oxygen from the fire. When carbon dioxide is released from the extinguisher, it displaces the surrounding oxygen, creating an oxygen-deficient environment. Since fire requires oxygen to burn, removing the oxygen effectively extinguishes the fire. Carbon dioxide also cools the fire to some extent, but its primary mechanism of action is suffocating the fire by removing the oxygen supply.

Class A fires are fires that involve ordinary combustible materials such as wood, paper, cloth, and plastics. These fires can be extinguished with water because water cools the fire, removes heat, and prevents re-ignition. It is important to note that water should not be used on fires involving flammable liquids, electrical equipment, or cooking oil, as it can be ineffective or even dangerous in these situations.

Fire extinguishers are designed to handle small fires, not large fires. They are typically effective for containing and extinguishing fires in their early stages when they are still small and manageable. However, when a fire becomes large and uncontrollable, it is not safe or effective to use a fire extinguisher. In such cases, it is best to evacuate the area and alert the fire department for professional assistance. Therefore, the statement that fire extinguishers can be effectively used for both small and large fires is false.

Fires do need heat to start. Heat is one of the three elements of the fire triangle, along with fuel and oxygen. Without heat, the fuel will not reach its ignition temperature and the fire will not start. Therefore, the statement that fires do not need heat to start is false.

The estimated number of workers who die in fire-related incidents per year is 200.

A Class C fire involves electricity because it is caused by energized electrical equipment or faulty wiring. In this type of fire, the source of ignition is an electrical current, and the fire can spread rapidly if not properly addressed. It is important to use appropriate fire extinguishing methods and avoid using water-based extinguishers, as they can conduct electricity and cause electrocution.

The statement "The three things to remember during a workplace fire emergency are stop, drop, and roll" is false. Stop, drop, and roll is a safety technique used in the event of a personal clothing fire, not a workplace fire emergency. In a workplace fire emergency, it is important to follow the established evacuation procedures, alert others, and use the designated fire exits to evacuate the building safely.
