already passed
Class A or B CDL is required to haul liquid gas in a tank or tanks having individually - correct answer
✔✔Rated capacity of more than 119 gallons and an aggravated rated capacity of 1,000 gallons or more
thst is either permanently or temporarily attached.
Before loading, unloading, or driving - correct answer ✔✔Inspect the vehicle
On all tank vehicles, it is most important to check: - correct answer ✔✔For leaks in the tank
If a tank is found to be leaking, the driver should: - correct answer ✔✔DO NOT CARRY OR HAUL. To do so
is a crime. You will be cited, prevented from driving further May also be liable for cleanup
Check Tank for: - correct answer ✔✔Dents or leaks. Make sure to check intake, discharge, and cut-off
valves. Make sure valves are in the correct position. Check pipes, connections, and hoses for leaks.
Especially around joints. Check manhole covers and vents; make sure they have gaskets. And keep them
clear.
Check Special Purpose Equipment - correct answer ✔✔Make sure your equipment works. This includes
the vapor recovery kits, grounding and bonding cables, emergency shut-off systems, and built in fire
extinguisher.
Never drive a tank vehicle with - correct answer ✔✔open valves or manhole covers
Driving Tank Vehicles - correct answer ✔✔Hauling liquids in tanks special skills because higher center of
gravity and liquid movement.
high center of gravity - correct answer ✔✔Much of the load is carried high up off the ground. This makes
it top heavy and easy to roll over.
,Danger of Surge - correct answer ✔✔Liquid surge results from movement in partially filled tanks. This
has a bad effect on handling. At a stop, liquid will surge back and forth.
When coming to a stop liquid surge can: - correct answer ✔✔Liquid will surge back and forth. When
wave hits end of the tank; it tends to push the truck in direction the wave is moving.
Loading bulkhead tanks - correct answer ✔✔Driver must pay attention to weight distribution. DO NOT
put too much weight in front or rear of tank.
Baffled tanks - correct answer ✔✔Have holes on them to let
Liquid flow through them. The baffles help control forward and backwards liquid surge. SIDE TO SIDE
surge can still happen
Food grade products (milk - correct answer ✔✔Are loaded in smooth bore in-baffled tanks.
Why do they load food products in non-baffled smooth bore tanks - correct answer ✔✔Because of
sanitation issues and not being able to clean baffles appropriately.
Use EXTREME caution driving no-baffle tanks / smooth bore tanks. - correct answer ✔✔Especially when
stopping and starting due to liquid surge.
Outage - correct answer ✔✔Never load a cargo tank totally full. You must leave room for liquids to
expand. They will expand as they warm. This is called "outage."
You must know the outage requirement when hauling liquids in bulk.
A full tank of dense liquids (such as some acids): - correct answer ✔✔May exceed weight limits. May
often be partially loaded
Amount of dense liquid depends on - correct answer ✔✔Amount of liquid
Weight of liquid
Legal weight limits
, Drive Smoothly - correct answer ✔✔Because of high center of gravity and surge. You must start and start
smoothly. This reduces surge and damage to equipment.
Controlling surge - correct answer ✔✔Keep steady pressure on brakes. DO NOT release too soon when
coming to a stop. Brake far in advance of a stop and increase following distance.
emergency stop to avoid crash - correct answer ✔✔Use controlled stab braking.
Steering quickly results in: - correct answer ✔✔Possible roll over.
When approaching a curve - correct answer ✔✔Slow down before reaching curve. Accelerate slightly
through the curve. Posted speed limit may be too fast for the curve.
Stopping distance when wet - correct answer ✔✔Doubles the normal stopping distance
Empty tanks - correct answer ✔✔May take longer to stop than full ones.
Skids - correct answer ✔✔DO NOT:
Over brake
Over steer
Over accelerate
Doing so may cause a jack knife. Must take immediate action if a skid starts.
When loading tanks - correct answer ✔✔Make sure valves are closed
Hauling liquids in tankers requires special care for two reasons. One reason is the _____ center of gravity
that tankers have. - correct answer ✔✔High center of gravity
