Since jurors sometimes give more weight to expert witness testimony than to lay opinions or closing arguments, finding topics in your case that are sufficiently beyond common experience will permit expert testimony. You may need to be imaginative in coming up with ideas for expert testimony. For example, industrial hygiene expert witnesses can be used in many ways. They are prepared to opine and write reorts on chemical hygiene plans, environmental management systems, industrial accident reconstruction, industrial chemicals, industrial chemical toxicology, industrial cleaning, industrial exhaust systems, industrial hygiene engineering, and industrial toxicology, among other topics. If your expert is not allowed to testify, be prepared with other testimony or evidence. It may also be possible to include the information in your closing argument.
