Study Notes
Escape Ramps
- Always use an escape ramp if brakes fail while driving a tanker.
Side to Side Surge
- Side to side surge can lead to a rollover of the tanker.
Liquid Outage
- Awareness of liquid outage is crucial because some liquids expand more with temperature increases.
Emergency Stopping
- Implement controlled or stab braking to stop a tank vehicle quickly to prevent crashes.
Skidding Causes
- Overacceleration, overbraking, and oversteering can all result in skidding; awareness of these factors is vital.
Tanker Driving Safety
- Curves and ramp speed limits are designed for cars and may not be safe for tankers; many tankers have high centers of gravity which contribute to rollover risks.
Fire Extinguisher Use
- Aim at the base of the fire and maintain an upwind position for effective fire extinguishing.
Emergency Steering
- During quick steering maneuvers, avoid applying brakes; maintaining grip on the steering wheel is essential.
Fire Types
- Water can be safely used to extinguish tire fires, but not electrical or gasoline fires.
Weight Distribution
- When unloading smaller tanks in a bulkhead setup, monitor weight distribution carefully.
Emergency Knowledge
- Understanding that heavy vehicles can turn more rapidly than they can stop is crucial during emergencies.
Caution with Smooth Bore Tanks
- Exercise caution during starting or stopping phases when driving smooth bore tanks due to potential surges.
Surge in Smooth Bore Tanks
- Smooth bore tanks experience more surge than tanks equipped with baffles, impacting vehicle stability.
Tank Load and Surge
- A smooth bore tank loaded to 50% capacity experiences more surge than when loaded to 100%.
Offramp Safety
- Slow to a safe speed before entering a curved downhill offramp to maintain control.
Surge Types in Baffled Tanks
- A liquid tank with baffles can still experience side-to-side surge despite mitigated movement.
Handling Skidding Front Wheels
- If the front wheels of a tanker begin to skid, the truck will continue moving forward in a straight line, regardless of steering input.
