A serious bodily injury with a retractable ladder leading to the attic

Investigations - After an accident on a retractable staircase, the civil liability insurer tries to determine the responsibilities and commissions our laboratory.


A retractable ladder gives way under the weight of the user and causes serious bodily injury. The civil liability insurer, who is seeking to determine liability, then appoints the INQUEST laboratory.

INQUEST’s know-how

The laboratory study identified a weakness in the design of the safety device, which gave way under duress.

The incident was reproduced on a new and identical product via a tensile test with a pneumatic cylinder stress test cage. It was then verified that the modification since made by the manufacturer makes the product safe and fit for use.
