Applies to establishments or individuals providing entertainment of a strenuous nature for a fee, donation or free of charge. For classification purposes, strenuous entertainment includes activities such as, but not limited to, dancing, skating, gymnastics, or performing stunts.

This classification excludes actors, players, performers, entertainers, or musicians whose routines or performances are not of a physical or strenuous nature who are to be reported separately in classification 6605.

Special note: Classifications 6620 and 6605 may be assigned to a single establishment provided the establishment maintains accurate records which distinguishes entertainers whose routines are of a physical and strenuous nature, from the routines which are not physical or strenuous. Care should be exercised when assigning this classification as the entertainers may be exempt from coverage as specified in RCW 51.12.020(9).
