USCG Exam PracticeFire extinguishers — types, ratings, requirements
A dry chemical stored pressure fire extinguisher without a pressure gauge, manufactured before January 1, 1965, is carried on a recreational vessel. The inspection record tag shows the last weight check ashore was conducted 7 months ago. Which statement correctly describes the regulatory status of this extinguisher?
- A. It remains acceptable because pre-1965 extinguishers are exempt from weight check intervals.
- ✓ It is no longer accepted as meeting required maintenance conditions until it is reweighed ashore and found serviceable.Correct
- C. It must be immediately replaced with an extinguisher manufactured after January 1, 1965.
- D. It is acceptable provided the frangible disc in the neck of the container is intact.
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 to be in serviceable condition, and within required weight conditions. The 7-month interval exceeds the 6-month limit, placing it out of compliance.
