Study Notes

Tanker Operation Essentials

Approach curves with caution by slowing down beforehand and accelerating slightly while navigating the curve to maintain control.
Do not fill the tank to maximum capacity; liquid expands during transit and legal weight limits must be considered.

Stopping and Skidding

A fully loaded tank vehicle does not take longer to stop than an empty one; the vehicle’s weight assists in slowing down.
Wet road conditions can double a tank vehicle’s stopping distance, emphasizing the need for cautious driving.
Skidding can be induced by three factors: over steering, over accelerating, and over braking.

Braking Techniques

Quick stops can be achieved using two braking methods: controlled braking and stab braking.

Vehicle Inspection and Regulations

Always conduct a thorough vehicle inspection before loading or driving a tank-equipped vehicle.
A tank endorsement is needed for transporting 119 liquid gallons in a permanently mounted cargo tank and 1000 gallons in a portable tank.
Consult the operator's technical manual for guidance on vehicle inspections.

Key Safety Considerations

Leaks are the most critical issue to visually inspect on a tank vehicle.
A vehicle described as "top heavy" tends to have a high center of gravity, increasing rollover risk.
Outage refers to the additional room left in the tank for liquid expansion.

Loading Considerations

Consider factors like liquid expansion, vehicle weight, and weight limits when determining the liquid load capacity.
Four essential items to inspect on a tank vehicle include: vapor recovery kit, ground/bonding cables, emergency shut-off system, and fire extinguishers.

Liquid Control Strategies

Control liquid surging by increasing following distance, applying steady brake pressure, and braking well in advance.
Special caution is required when driving tank vehicles due to the high center of gravity and liquid movement within the tank.

Tank Design Differences

Bulkheads are solid walls within the tank, while baffles are designed with holes allowing liquid to flow through, reducing surge.

Operating Speeds and Safety

Never operate tank vehicles through curves on ramps or off-ramps at posted speed limits or higher, as reduced speeds are necessary for safe navigation.
Smooth bore tankers experience more severe forward and backward surge compared to tankers equipped with baffles.

Understanding Liquid Movement

Liquid surge refers to the longitudinal movement of liquid in a tank that isn't fully filled, affecting vehicle stability during transit.
