Tankers 3

Except for when you are loading or unloading a cargo tank, the liquid discharge valves on a compressed gas tank should always be:

• closed.

• open.

• unlatched.

Tankers that are used to transport liquid food products:

• often have very strong forward-and-back surge.

• should always have baffles.

• are not affected by side-to-side surge.

If you are driving a tanker and need to steer quickly to avoid a hazard you:

• should not apply the brakes while turning.

• will find that tankers are easier to counter-steer than most vehicles.

• should never leave the roadway.

When loading the individual tanks of a tanker that is equipped with bulkheads, you should make sure that:

• most of the weight is toward the front of the vehicle.

• the middle tanks contain the largest amount of liquid.

• all the tanks are filled evenly.

A full tank of dense liquids (such as some acids):

• gives you more stability for going around turns.

• should only be carried in smooth bore tanks.

• may often exceed legal weight limits.

Portable tanks:

• are not allowed to carry loads that are more than 1000 gallons.

• can only be loaded when they are attached to the vehicle.

• are bulk containers which are not permanently attached to the truck.

You are driving on a clear night with your low beam headlights on. If your headlights let you see about 250 feet ahead of you, adjust your speed so that you can stop within about ___ feet.

• 100

• 250

• 500

Vehicle skids are most often caused by:

• driving too fast.

• driving with bald tires.

• loose material on the road surface.

A liquid tank with baffles can still have what kind of surge?

• Side-to-side.

• Front-to-back.

• Top-to-bottom.

The amount of liquid you may put into a tank:

• should always fill it to the brim to reduce surge.

• depends on the liquid's center of gravity.

• may be required to be less than full to stay within weight limits.
