USCG Exam PracticeFire extinguishers — types, ratings, requirements
A dry chemical stored pressure fire extinguisher without a pressure gauge or indicating device was manufactured in 1962 and is carried aboard a recreational vessel. The inspection record tag shows the last weight check ashore was performed 7 months ago. Under 33 CFR §175.310(d), what is the required action?
- A. The extinguisher remains acceptable because it was manufactured before January 1, 1965.
- ✓ The extinguisher must be reweighed ashore and found serviceable before it is again accepted as meeting required maintenance conditions.Correct
- C. The extinguisher must be immediately replaced with a currently approved model.
- D. The extinguisher is acceptable provided the outer seal is intact and the frangible disc has not been broken.
Why B is correct
33 CFR §175.310(d)(1) states that when the inspection record tag shows 6 months have elapsed since the last weight check ashore, the extinguisher is no longer accepted as meeting required maintenance conditions until it is reweighed ashore, found serviceable, and within required weight conditions. The 7-month interval exceeds the 6-month threshold, so reweighing is required before the extinguisher can again count as required equipment.
