Minimum distance from the floor to a mounted portable extinguisher often required?

• A. Six inches
• B. Four inches
• C. Two inches
• D. Ten inches

Answer: (B)

The idea being tested is how high a portable extinguisher should be mounted off the floor so it stays accessible and protected. Four inches is the commonly specified minimum clearance to keep the bottom of the extinguisher off the floor. This small gap helps prevent moisture, dust, or cleaners from contacting the unit and makes it easier to grab from the mounting bracket without scraping the floor. Six inches would be higher than necessary for a minimum, and two inches is too close to the floor to stay clear of moisture or debris. Ten inches would place the extinguisher quite high, making it harder to reach quickly in an emergency. So, four inches is the best answer because it balances protection with quick, reliable access.
