Playground Swing
Failure
Metallurgical
failure analysis was requested of a playground swing set chain
which failed,
resulting in injury to a child. Examination revealed that the
design of the swing seat caused the s-link that joined
the seat to the chain to wear and eventually break,
releasing the swing seat and the swing user.
