The HSE RAPP tool classes containers with three or more wheels (roll cages, for example) by total mass, and the container's own weight counts toward it.

Total massRisk
under 250 kgLow
250-500 kgMedium
500-750 kgHigh
over 750 kgVery high

GEBHARDT Isotec TBX models of 410-795 litres carry 500 kg and those of 900 litres and above carry 700 kg. A TBX loaded with 500 kg lands in the high band once its own weight is added; one loaded with 700 kg comes up against the 750 kg limit. Filling to capacity is not compulsory: where a store has no dock and one person receives, a lower fill is an operating decision.

The tool scores the route too: a 3-5 degree slope is medium; ramps steeper than 5 degrees, steps and wet floors are high; a route over 10 m adds points. Pushing the loaded container once along the real route and watching whether the user struggles gives the final answer.
