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.
