Bulk Liquids & SurgeQuestion 18 of 60
Why might you be unable to fill a cargo tank completely even when it is under the weight limit?
a.The pump cannot reach the top of the tank
b.Full tanks are illegal in all states
c.You must leave outage space for the liquid to expand
d.The baffles block the top of the tank
Explanation
Even if weight is not the limiting factor, you must leave outage so the liquid has room to expand as it warms. Loading a tank totally full leaves no room for expansion and can rupture it. The required outage depends on the specific liquid being hauled.
