Determining Which HCs Exceed Thresholds (continued) |
||||||
The following steps of this module involves using the Optional Aggregation Worksheet B(s) to aggregate quantities of EHSs contained in each mixture and location at the facility. The worksheet is a useful tool but is not a regulatory requirement. You do not need to use copies of the Optional Aggregation Worksheet B if the facility has an other system which can accomplish the same goals (such as a computerized inventory). | ||||||
