Make sure valves are in the correct position before loading, unloading, or moving the vehicle.
checks pipes connections and hoses especially around joints
check manhole covers and vents --make surethe covers have gaskets and they close correctly
Keep the vents clear so they work correctly
Check Special Purpose Equipment
Vapor recovery kits
Grounding and bonding cables
Emergency shut off systems
Built in Fire Extinguisher
Some tanks are divided into several smaller tanks, when loading and unloading the smaller tanks...pay attention to weight distribution Dont put too much weight on the front or rear of the vehicle
Baffled Tanks have bulkheads with holes to let the liquid flow through. Helps to control the forward and backward surge. Side to Side surge can still occur and cause rollover
AKA "smooth bore" tankers...have nothing inside to control flow of liquid...usually for transporting food,,,milk for example
Never haul liquids completely full..Liquids expand when they get warm and each liquid expands differently this is called outage...know the outage requirement for the liquid your hauling
full tanks of a dense liquid such as some acids may exceed legal weight limiits to know the legal amount to haul you must know
amount the liquid will expand in transit
weight of the liquid
legal weight limits
