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.
