Bulk Liquids & SurgeQuestion 21 of 60
Which statement about baffled tanks is TRUE?
a.They completely prevent all liquid surge
b.They are required for hauling milk and food products
c.They increase forward and backward surge
d.They reduce forward-and-back surge but not side-to-side surge
Explanation
Baffles have holes that slow the forward and backward flow of liquid, reducing that surge. However, they do little to control side-to-side surge in curves and lane changes. Drivers of baffled tanks must still be cautious of lateral movement and rollover.
