1.
Smoke can hurt you but it can't kill you.
Correct Answer
B. False
Explanation
This statement is false. Smoke can indeed kill you. Inhaling smoke can cause damage to the respiratory system, leading to serious health issues such as lung cancer, chronic obstructive pulmonary disease (COPD), and even death. Smoke inhalation can also lead to asphyxiation or carbon monoxide poisoning, both of which can be fatal. Therefore, it is important to avoid exposure to smoke and ensure proper ventilation in case of a fire or other situations where smoke is present.
2.
It can take only 3 minutes to go from a tiny flame to a raging fire.
Correct Answer
A. True
Explanation
The statement is true because under certain conditions, a small flame can quickly grow into a large and uncontrollable fire. Factors such as the presence of flammable materials, oxygen supply, and favorable weather conditions can contribute to the rapid spread of fire. Additionally, the heat generated by the initial flame can ignite nearby combustible materials, causing the fire to intensify and spread even faster. Therefore, it is important to take immediate action and extinguish small flames before they have the chance to escalate into a raging fire.
3.
Fire is a serious threat in a hospital because patients may not be able to evacuate on their own.
Correct Answer
A. True
Explanation
Fire is a serious threat in a hospital because patients may not be able to evacuate on their own. This is true because hospitals often have patients who are immobile, unconscious, or require medical equipment to support their lives. In the event of a fire, these patients would need assistance and may not be able to evacuate quickly without help. Therefore, fire safety measures and evacuation plans are crucial in hospitals to ensure the safety of patients and staff.
4.
Fire develops from a mix of which three components?
Correct Answer
A. Heat, fuel, and oxygen
Explanation
Fire develops from a mix of heat, fuel, and oxygen. Heat provides the initial energy to start the fire, fuel acts as the material that can burn, and oxygen is necessary for the combustion process. These three components work together in a chemical reaction called combustion, where the fuel reacts with oxygen in the presence of heat to produce flames and release energy in the form of heat and light. Without any of these three components, a fire cannot occur.
5.
Fires can be prevented by:
Correct Answer
E. All of the above
Explanation
The correct answer is "all of the above" because inspecting electrical appliances for damage, not using extension cords, smoking only in designated areas, and safely preparing food are all effective ways to prevent fires. By inspecting electrical appliances for damage, any potential hazards can be identified and addressed before they cause a fire. Not using extension cords reduces the risk of overloading electrical circuits, which can lead to fires. Smoking only in designated areas helps prevent accidental fires caused by discarded cigarette butts. Safely preparing food, such as avoiding leaving cooking unattended, reduces the risk of kitchen fires. Therefore, all of these actions contribute to fire prevention.
6.
Combustible gases or iquids are Class A fuels.
Correct Answer
B. False
Explanation
Combustible gases or liquids are not classified as Class A fuels. Class A fuels are typically solid materials that are capable of sustaining combustion, such as wood, paper, and cloth. Combustible gases or liquids fall under different classifications, such as Class B for flammable liquids or Class C for flammable gases. Therefore, the correct answer is false.
7.
When using a fire extinguisher, you should aim the spray at the shooting flames.
Correct Answer
B. False
Explanation
When using a fire extinguisher, you should not aim the spray directly at the shooting flames. Instead, you should aim the fire extinguisher at the base of the fire. This is because the base of the fire is where the fuel source is located, and by targeting the base, you can effectively cut off the supply of fuel and extinguish the fire. Aiming at the shooting flames may not effectively control the fire and could potentially spread it further.
8.
R.A.C.E. stands for "rescue, alarm, confine, extinguish".
Correct Answer
A. True
Explanation
The statement is true because R.A.C.E. is an acronym commonly used in fire safety procedures. It stands for "rescue, alarm, confine, extinguish" and is a sequential guide for responding to a fire emergency. "Rescue" refers to ensuring the safety of individuals in the vicinity, "alarm" involves activating the fire alarm system, "confine" means closing doors and windows to contain the fire, and "extinguish" pertains to using appropriate firefighting methods to put out the fire.
9.
You should take a headcount of everyone in the area before you evacuate, so you will know if everyone got out.
Correct Answer
A. True
Explanation
Taking a headcount of everyone in the area before evacuating is important because it allows you to ensure that everyone has safely left the area. By counting the number of individuals present, you can confirm that no one is left behind or missing. This helps to ensure the safety and well-being of all individuals involved in the evacuation process.
10.
You should always check closed doors for heat before opening them.
Correct Answer
A. True
Explanation
It is important to check closed doors for heat before opening them because heat can indicate the presence of a fire on the other side. By checking for heat, you can assess the safety of opening the door and potentially prevent harm or injury. This precautionary measure is especially crucial in emergency situations to avoid walking into a dangerous environment.
11.
When evacuating through smoke, keep low and try to cover your nose with a wet cloth.
Correct Answer
A. True
Explanation
When evacuating through smoke, it is important to keep low because smoke rises and can contain harmful gases and particles. By staying low, you can minimize your exposure to these hazards. Additionally, covering your nose with a wet cloth can help filter out some of the smoke and provide a barrier for your respiratory system. This can help reduce the risk of inhaling toxic substances and improve your chances of safely evacuating from the smoke-filled environment.
