Transportation Of Dangerous Goods: BulkRoll Over Accidents and Prevention Paul Vincent.K | Air Liquide Emirates | Dubai | 5th December 2013
Objective: • Awareness on vehicle roll over accidents , causes and prevention. Topics Discussed: • Vehicle Rollover safety statistics – IG industry (SAG_NL_88_09_E) • Vehicle Rollover Causes • Vehicle Rollover Prevention
VehicleRollover Incidents • 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 • Are these isolated events? • 58% ends up in driver fatalities, • 95% in hazardous material spills • average direct costs of $120,000 per event.
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.

HIGH WAY Factors: Adapt your speed to the environment Sharp curves / Steep grades Do not go onto the shoulder, especially when it rains Poor visibility / Narrow drive ways
DriverFactors: • Excessive speed • Cell Phone use • Driver Complacency • Fatigue • Under influence • Physical conditions • Mental conditions • Day dreaming • Eating in the cabin
