Study Notes

Tanker Operations and Safety

Emergency stops for tankers should utilize controlled or stab braking.
Smooth bore tanks are identified as un-baffled liquid tankers, leading to unique handling challenges.
Side-to-side liquid surge can result in rollover incidents.
Hauling liquids requires attention to high centers of gravity and liquid movement.
Liquid surge causes truck movement in the direction of liquid waves, impacting handling.

Tank Design Features

Baffled tankers contain bulkheads with holes allowing liquid flow, aiding in surge management.
Outage refers to the allowance for liquid expansion; essential for safe transport.
Liquid-tight separators within tank compartments are termed bulkheads.
Partially filled tanks exhibit liquid movement known as surging.

Driver Awareness and Responsibilities

Understanding the effect of cargo weight on handling, as center of gravity in tankers is typically higher.
A tank endorsement is necessary for vehicles transporting liquids and gases.
Conditions, such as wet roads, can significantly increase stopping distances.

Surge Dynamics

Tanks with baffles can still experience side-to-side surge but have reduced front-to-back surge.
Best practice for navigating curves includes reducing speed pre-curve and potentially accelerating slightly through.

Loading and Weight Distribution

The volume of liquid loaded is governed by both legal weight limits and its expansion properties.
It is crucial to check the distribution of weight when loading small tanks within cargo tanks equipped with bulkheads.

Night Driving and Stopping Distances

When dimming headlights at night, adjust speed to ensure stopping distance aligns with visibility range.
Empty trucks can have longer stopping distances compared to loaded ones due to reduced traction.
