(You should also study Sections 2 , 5 , 6 , and 9) . A tank endorsement is required for certain vehicles that transport liquids or gases. the liquid or gas does not have to be a hazardous material. A tank endorsement is required if your vehicle needs a class A or B cdLand you want to haul a liquid or liquid gas in a permanently mounted cargo tank rated at greater than 450 liters (119 gallons) or a portable tank rated at 1 ,000 gallons or more. A tank endorsement is also required for class c vehicles when the vehicle is used to transport hazardous materials in liquid or gas form in the above described rated tanks.  \nBefore loading, unloading, or driving a tanker, inspect the vehicle. this makes sure that the vehicle is safe to carry the liquid or gas and is safe to drive.  \n8.1 – InsPectInG tanK veHIcles  \ntank vehicles have special items that you need to check. tank vehicles come in many types and sizes. You need to check the vehicle’s operator manual to make sure you know how to inspect your tank vehicle.  \n8. 1. 1 – Leaks  \non all tank vehicles, the most important item to check for is leaks. check under and around the vehicle for signs of any [leaking. do](leaking. do) not carry liquids or gases in a leaking tank. to do so is a crime. You will be cited and prevented from driving further. You may also be liable for the clean up of any spill. In general, check the following:  \n• check the tank’s body or shell for dents or leaks.  \n• check the intake, discharge, and cut-off valves. make sure the valves are in the correct position before loading, unloading, or moving the vehicle.  \n• check pipes, connections, and hoses for leaks, especially around joints.  \n• check manhole covers and vents. make sure the covers have gaskets and they close correctly. Keep the vents clear so they work correctly. never drive a tank vehicle with open valves or manhole covers.  \n8. 1.2 – Check Special Purpose Equipment  \nIf your vehicle has any of the following equipment, make sure it works:  \n• vapor recovery kits.  \n• Grounding and bonding cables.  \n• Emergency shut-off systems.  \n• Built in fire extinguisher.  \n8. 1.3 – Special Equipment  \ncheck the emergency equipment required for your vehicle. Find out what equipment you are required to carry and make sure you have it (and it works) .  \n8.2 – Driving Tank Vehicles  \nHauling liquids in tanks requires special skills because of the high center of gravity and liquid movement. See Figure 8.1.  \n8.2. 1 – High Center of Gravity  \nHigh center of gravity means that much of the load’s weight is carried high up off the road. this makes the vehicle top-heavy and easy to roll over. Liquid tankers are especially easy to roll over. tests have shown that tankers can turnover at the speed limits posted for curves. take highway curves and on ramp/off ramp curves well below the posted speeds.  \n8.2.2 – Danger of Surge  \nLiquid surge results from movement of the liquid in partially  \nfilled tanks. this movement can have bad effects on handling. For example, when coming to a stop, the liquid will surge back and forth. When the wave hits the end of the tank, it tends to push the truck in the direction the wave is moving. If the truck is on a slippery surface such as ice, the wave can shove a stopped truck out into an intersection. the driver of a liquid tanker must be very familiar with the handling of the vehicle.  \n8.2.3 – Bulkheads  \nSome liquid tanks are divided into several smaller tanks by bulkheads. When loading and unloading the smaller tanks, the driver must pay attention to weight distribution. Fill tanks evenly and do not put too much weight on the front or rear of the","cbCaijxHANxxllPk","https://ap.wps.com/l/cbCaijxHANxxllPk","pdf",151357,"English","# Inspecting Tank Vehicles\n## Leaks\n## Check Special Purpose Equipment\n## Special Equipment\n# Driving Tank Vehicles\n## High Center of Gravity\n## Danger of Surge\n## Bulkheads\n## Baffled Tanks\n## Un-baffled Tanks\n## Outage\n## How Much to Load?\n# Safe Driving Rules\n## Drive Smoothly\n## Controlling Surge (Braking)","[{\"question\":\"When is a tank endorsement required for tank vehicles?\",\"answer\":\"A tank endorsement is required for certain vehicles transporting liquids or gases in permanently mounted cargo tanks over 450 liters (119 gallons) or portable tanks rated at 1,000 gallons or more.
