USCG Exam PracticeBatteries and storage systems
Under 46 CFR §111.15-2, a battery cell tested for electrolyte spillage must not spill electrolyte when inclined at what angle from the vertical, and under 46 CFR §28.870, the corresponding requirement for emergency battery installations is what angle?
- A. §111.15-2 requires 30 degrees; §28.870 requires 40 degrees
- ✓ §111.15-2 requires 40 degrees; §28.870 requires 30 degreesCorrect
- C. Both regulations require 40 degrees from the vertical
- D. Both regulations require 30 degrees from the vertical
Why B is correct
46 CFR §111.15-2(a) sets the no-spill requirement at 40 degrees from the vertical, while 46 CFR §28.870(c)(2) sets the requirement for emergency battery installations at 30 degrees from the vertical. The two regulations apply to different vessel categories and specify different angles.
