Instructor-led discussion of tanker / water tender driver-operator topics. Officer selects focus. Topics that fit this sheet include: tanker / tender types (vacuum tanker, gravity dump, pumper-tanker combo, nurse tanker), tank capacity and weight calculations (water = 8.34 lb/gal — a 3000 gal tanker carries 25,000 lb of water), tank baffle requirements (NFPA 1901 — internal baffles, surge protection), fluid dynamics and rollover risk (high center of gravity, surge effect on cornering and braking), driving a loaded tanker (acceleration, braking distance, cornering, stopping on grade), dump operations (rear dump, side dump, gravity vs pumped, dump valve operation), jet siphon / jet dump for portable tank transfer, portable tank deployment and water sharing, fill site operations (drafting from a hydrant or pond into the tanker), nurse operations (tanker stays connected and supplies pumper), tanker shuttle operations (cycle time = travel + fill + dump, calculating GPM equivalent), rural water supply planning (NFPA 1142), and tanker rollover prevention and post-incident analysis (the #1 cause of tanker fatalities). Reference: NFPA 1002 Ch. 5, NFPA 1142, NFPA 1901, NFPA 1911, IFSTA Pumping Apparatus D/O. Document specific topic covered.
