Are these one off issues or an industry problem?

Road transportation is the highest risk activity in industrial gases industry.

What / Who are at risk ?

Individuals, Employee drivers / Expensive company & third party assets

Main Causes of Roll- Over Accidents

Vehicle Design – High center of gravity

Load Effects – Slosh and surge

Highway factors – Steep grades / Sharp curves / limited visibility / soft shoulders

Driver factors – Excessive speed / fatigue / cell phone usage / under influence etc.

Vehicle Design – COG (Center of Gravity)Trailer design can lower the centre of gravity of the vehicle & load and

improve stability.
