A non-rechargeable boat fire extinguisher expires how long after the date stamped on its bottom?
12 years.
- 5 years
- 42 months
- 12 years ✔
Why: Each time you head out, check that seals and tamper indicators are intact, the gauge reads in range, there's no damage, and it isn't expired. Non-rechargeable units expire 12 years after the date stamp.
Huh, didn't know that: A partly used extinguisher must be replaced or recharged, even if it still has some agent left.
Why did the fire extinguisher get a birthday cake? To check its date stamp.
