PPE must be dry before use at a structural fire as trapped water in the fabric can cause steam burns in _____ conditions.
- A.
High heat
- B.
Hazardous
- C.
High heat index
- D.
Fire
Correct Answer
A. High heatExplanation
Trapped water in PPE fabric can cause steam burns in high heat conditions. When exposed to high heat, the water trapped in the fabric can quickly turn into steam, which can cause burns on the wearer's skin. Therefore, it is important for PPE to be dry before use in order to prevent this potential injury.Rate this question:

____ refers to the time a wearer has before a second degree or greater burn will be sustained.
- A.
Thermal protective performance (TPP)
- B.
Personal Protective Equipment (PPE)
- C.
Thermal protective equipment longevity (TPEL)
- D.
Equipment Fire Life (EFL)
Correct Answer
A. Thermal protective performance (TPP)Explanation
Thermal protective performance (TPP) refers to the time a wearer has before a second degree or greater burn will be sustained. It measures the ability of a material or garment to protect against heat and flames. The higher the TPP value, the longer the wearer can be exposed to heat before sustaining a burn injury.

Backdraft potential range
Correct Answer
A. Flammable/ explosive rangeExplanation
The correct answer is flammable/explosive range. This refers to the range of concentrations of a flammable substance in the air that can result in an explosion or fire if ignited. It includes the lower explosive limit (LEL), which is the minimum concentration required for combustion, and the upper explosive limit (UEL), which is the maximum concentration above which combustion cannot occur. Understanding this range is important for ensuring safe handling and storage of flammable materials.Rate this question:
-
- 39.
Weight of vapor or gas compared to the weight of air (air is given the value of 1) is vapor density.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Vapor density is a measure of the weight of a vapor or gas compared to the weight of air. It is calculated by dividing the weight of the vapor or gas by the weight of an equal volume of air. Since air is given the value of 1, a vapor density greater than 1 means that the vapor or gas is heavier than air, and a vapor density less than 1 means that it is lighter than air. Therefore, the statement "Weight of vapor or gas compared to the weight of air (air is given the value of 1) is vapor density" is true.Rate this question:

Chemical reaction between two or more chemicals that produces heat energy
- A.
Exothermic reactions
- B.
Endothermic reactions
- C.
Backdraft potential
- D.
Flashpoint
Correct Answer
A. Exothermic reactionsExplanation
Exothermic reactions refer to chemical reactions where heat energy is released. This means that the reactants have more energy than the products, resulting in a net release of energy in the form of heat. In these reactions, the temperature of the surroundings increases. This is in contrast to endothermic reactions, where heat energy is absorbed from the surroundings, causing a decrease in temperature. The terms "backdraft potential" and "flashpoint" are unrelated to the given statement and do not pertain to the concept of heat energy release in chemical reactions.Rate this question:

- D.
Thermal layering
Correct Answer
A. Endothermic reactionsExplanation
Endothermic reactions are chemical reactions that absorb heat or require heat to be added. In these reactions, the reactants have lower energy than the products, and energy is absorbed from the surroundings to make up the difference. This results in a decrease in temperature of the surroundings. Examples of endothermic reactions include the reaction between baking soda and vinegar, or the reaction between ammonium nitrate and water.Rate this question:

An explosion caused by the rupture of a vessel containing a pressurized liquid that has been heated above its boiling point.
- A.
Boiling liquid expanding vapor explosion
- B.
Thermal layer explosion
- C.
Spontaneous combustion
- D.
Backdraft explosion
Correct Answer
A. Boiling liquid expanding vapor explosionExplanation
A boiling liquid expanding vapor explosion refers to an explosion that occurs when a vessel containing a pressurized liquid is heated above its boiling point. As the liquid boils, it rapidly expands into vapor, causing a sudden increase in pressure within the vessel. If the pressure becomes too high, the vessel ruptures, resulting in a violent explosion. This type of explosion is specifically caused by the combination of a heated liquid and pressurized conditions, making it different from other types of explosions such as thermal layer explosions, spontaneous combustion, or backdraft explosions.Rate this question:
