Recreation, sports, and gym equipment are subjected to large dynamic forces and must be designed to support these loads and protect users from unintentional hazards. Adequate instructions and warnings may be required if their assembly and proper use are not obvious. There are also issues associated with safety, adequate supervision and maintenance of gyms, swimming pools and playgrounds to assure that they are used properly and do not become dangerous due to either misuse or normal wear and tear. Issues associated with such accidents require an understanding of biomechanics, human factors, safety, dynamics and structural engineering.
Expertise

The largest storage rack/ retrieval system, larger than two football fields and eighty feet wide was constructed to store 108 million pounds of paper products. On July, 2002, after two months of use, the facility collapsed and sparked a fire that destroyed the entire structure and 45 million pounds of paper. Nearly 50 fire departments responded to the inferno, which burned for three weeks. The owner of the facility sued a number of companies that included the contractor that designed and built the structure, a subcontractor, and the company that supplied the 110 foot steel columns.
For those readers who remember Jayne Mansfield, or even know who she was, this is not a story about her Hollywood exploits or bedroom acrobatics. It is a story about a common type of accident - a rear-ender involving an automobile striking a truck or bus - often referred to, in accident reconstruction circles, as "the Jayne Mansfield syndrome."
A motorist exiting a rural freeway was struck by a motorist on the intersecting State Route at the top of the exit ramp. At the westbound exit ramp from the Interstate freeway the State Route a stop sign is posted at the end of the ramp requiring exiting traffic to stop before entering the State Route. However, the eastbound off ramp traffic is not required to stop before entering the State Route. A stop sign is posted on southbound State Route at the ramp terminal. This is an unusual traffic signing pattern for interstate off ramps. Expert observations of the operation of this intersection showed that a large proportion of the eastbound off ramp traffic slowed down at the end of the ramp, expecting to stop at the State Route.
