Recommended Actions / Learning Points
- An exclusion zone to be established around the designated tipping location to prevent personnel and vehicle access within the ‘danger area’.
- Ground at designated tipping area checked (confirmed) to ensure level and solid.
- Inspect tipping valves on all hauliers’ trailers with similar mechanism.
- Communicate this incident to all tipping vehicle delivery drivers and site personnel to ensure they understand the root cause and are extra vigilant (Haulier)
- In the short term, a company representative to assist the tipping of all fuel tipping trailers.
- All other tipping activities reviewed.
- Ensure check of tipping valve operation is included in driver daily checks from now on and add a more thorough check by a mechanic to trailer annual maintenance check or similar (Haulier)
- Modern controls only operate when the lever is pushed to raise or lower and should return to neutral automatically as soon as hand is taken off the control.
- Checks should also include the safe and effective operation of the tailgate mechanism.
Additional considerations beyond the scope of this specific incident but reflecting engineering solutions that can mitigate risks whilst tipping.
1.Use of vehicles with the tipping gear control in the cab.
The driver can remain located in the cab with a seat belt on and the cab door closed. The driver can observe the discharge via mirrors or cameras. One advantage of the rear camera on tippers – it that if configured correctly you can observe the discharge. Some companies specify the tipping gear controls to be fitted on the left side of the driver’s seat – so the driver must be physically in the driver seat to operate.
In many vehicles the control leaver is located on the left side of the driver’s seat, but the driver is still able to operate from ground with driver stood outside with the door open.
Situations where a driver is able to operate the tipping gear controls whilst outside the vehicle means that he is located within the exclusion zone and cannot observe as much as when located in the cab, increasing the risk for the driver and others.
2. Use of inclinometers
Many vehicles are now fitted with inclinometers that provide warnings and/or automatically stop or prevent the tipping process if outside safe parameters.
3. Use of structures that prevent overturns see image below typical structure
