This classification shall not be used for division of payroll in connection with any other classification (other than the Standard Exceptions or General Exclusions) unless the operations described by Classification 3146(2) constitute a separate and distinct enterprise having no connection with the operations covered by any other applicable classification.
The Classification Search was developed by the WCIRB for your convenience to help you identify Standard Classifications based on keywords or a classification code. However, you cannot rely solely on the Classification Search and must make an independent assessment when determining the appropriate classification(s) assignable to a risk in accordance with the USRP.
