Final answer:
Larger fire extinguishers tend to have longer discharge times than smaller ones, and discharge time is an important factor in fire safety.
Step-by-step explanation:
The correct answer to the question about the relationship between fire extinguisher size and discharge times is: Larger extinguishers generally have longer discharge times compared to smaller extinguishers. This is because larger extinguishers typically hold more extinguishing agent and expect to discharge that agent over a more prolonged period to tackle a fire effectively. However, the exact discharge time can vary depending on the type of extinguisher and the manufacturer's specifications. Discharge time is certainly not irrelevant in fire safety; in fact, it is a crucial factor to consider when selecting the right extinguisher for a specific situation. The correct statement regarding fire extinguisher size and discharge times is b) Smaller extinguishers have longer discharge times. The discharge time of a fire extinguisher is determined by the volume of extinguishing agent it contains and the rate at which it is expelled. Smaller fire extinguishers typically have a smaller volume of extinguishing agent, resulting in a longer discharge time.
