A dropped object can damage equipment causing structural and environmental damage, which can have serious financial consequences. Even more seriously, a dropped object can injure personnel and cause death.
When an object is dropped, its weight causes it to accelerate downwards. When the object collides with a surface, it exerts a force upon that surface, which can cause damage. This is known as the impact force.
The heavier an object and the greater the height, the more forceful the impact.
Meaning heavier objects dropped from greater heights will cause the most damage on average.
As well as weight and height, the design and shape of an object can affect the type of damage that is caused. Tools with sharp and pointed edges, such as screwdrivers, wrenches and nails, can penetrate on impact and this makes them particularly dangerous so obviously they must never be dropped.
