Laststyrt

Laststyrt is a Norwegian term used to describe a failure mode in which a load shifts or a load carrier loses stability, causing tilting, collapse, or rollover. The word is formed from last (load) and styrt (collapse or topple). In professional contexts, laststyrt may refer to incidents in road transport, maritime handling, rail freight, or construction when improper securing, distribution, or dynamic forces lead to an abrupt change in center of gravity.

Causes of laststyrt include poorly secured cargo, uneven stacking, high center of gravity of equipment or loads, sharp maneuvers, braking, acceleration, wind loads, or seismic forces. Environmental conditions, such as wet or uneven surfaces, can also contribute. The consequences range from damage to goods and equipment to injuries or fatalities and project delays. The term emphasizes the stability aspect of a system and is used in safety reports and risk assessments to describe tipping-related events rather than simple slippage.

Prevention focuses on proper load securing and distribution, routine checks of restraints and containment, and training for personnel involved in loading, unloading, and transport. Engineering controls may include designing transport units and storage areas to minimize lateral movement, using appropriate tie-downs, edge protection, anti-slip measures, and ensuring loads are within the equipment’s stable limits. Compliance with relevant standards and regular risk assessments are commonly recommended.
