Explanation:

Analyze the first question on extinguisher effectiveness

The first question asks for the most important factor in determining the effectiveness of an extinguisher in dousing a fire.

• The user, wind direction, and size of the extinguisher are practical factors during operation.
• However, if the extinguishing agent is not compatible with the class of the fire (for example, using water on a Class B grease fire or Class C electrical fire), the extinguisher will be completely ineffective or even dangerous. Therefore, matching the extinguisher to the class of the fire is the most critical factor.

Analyze the second question on the PASS method

The second question asks for the fourth step in the PASS method of extinguisher operation.

• The PASS acronym stands for:

1. Pull the pin.
2. Aim at the base of the fire.
3. Squeeze the lever.
4. Sweep from side to side.

• Therefore, the fourth step is "sweep".

Answer:

Question 1

• user.
• wind direction.
• size of the extinguisher.
• class of the fire. (Correct answer)

Question 2

• sweep. (Correct answer)
• squeeze.
• spray.
• soak.
