US Patent 7921758 Impact panels

A technique enables improved performance of oilfield service operations. A protective shield is formed with a portable stand and at least one lightweight impact panel. The one or more lightweight impact panels enable easy movement of the safety shield from one location to another at a given well site or between different well sites, thus affording protection with a minimum of labor and set up time. The safety shield can be used to provide protection during individual operations and/or to segregate and protect independent operations from each other during multiple, simultaneous operations.
