All of the above. Tankers have a high center of gravity which increases the risk of rollover. Liquid surge (movement of liquid in partially filled tankers) can also have negative effects on handling.
Baffles. Baffles are bulkheads that have holes in them to let liquid flow through.
To control forward-and-back liquid surge. Baffles are bulkheads that have holes in them to let liquid flow through. Baffles help control forward and backward liquid surge but not side to side liquid surge.
To reduce the chance of leaks due to liquid expansion. Outage is the free space left in a tanker to allow for expansion of the liquid from temperature changes.
Slow down before the curve, then accelerate through the curve. Because tankers have a high center of gravity, there is an increased risk of rollovers, especially on curves. You should drive at speeds well below the posted speed.
Outage requirements vary across liquids. Different liquids expand by different amounts resulting in different outage requirements.
Side to side. Baffled tanks are designed to control forward and backward surge. Side to side surge can still occur, which may result in rollovers.
The baffled tanker will have less front to back surge than the unbaffled tanker. Baffled tanks are designed to control forward and backward surge. Side to side surge can still occur, which may result in rollovers.
Rollover. A side to side surge may increase your chance of rollover by exerting force sideways on your vehicle.
Bulkhead. Bulkheads divide a tank into several smaller separate tanks. Baffles are bulkheads that have holes in them to let liquid flow through.
