MAINTENANCE HAZARDOUS WASTE MANUAL <br />Chapter 2 <br />Page 13 <br />F. Manufacturers original containers that are now empty must be labeled <br />"empty" and dated. For example: <br />1. empty drums <br />2. caustic soap containers <br />3. petroleum products <br />4. paints <br />5. similar original containers <br />These are the labeling requirements during the storage of hazardous waste. A sample of <br />the required label is shown in Appendix A: Hazardous Waste Label, Storage and <br />Disposal. Examples of completed labels are located in Appendix A, Hazardous Waste <br />Label, Storage, and Disposal. For transportation, the label requirements are more <br />complex and your contractor will supply the needed labels. The contractor shall also <br />supply proper U.N. and/or N.A. numbers and any other information needed for shipping. <br />2.02 Storage Containers <br />The containers used to store hazardous waste are an important safe guard for employees <br />and the environment. The following regulatory requirements and Caltrans guidelines <br />for hazardous waste containers will be followed: <br />A. Containers must meet Department of Transportation (DOT) requirements for <br />transportation on highways. (Title 49 Code of Federal Regulations). Containers <br />used to transport or store hazardous waste must be free of leaks and undamaged. <br />B. Hazardous waste must be placed into compatible containers. (For example: <br />corrosives must be placed into polyethylene type drums; solvents must be placed <br />into steel drums). The container shall be made of/or lined with material that will <br />not react with the hazardous waste stored in it. <br />C. Containers used to store hazardous waste shall be in good condition. If a <br />container is not in good condition (e.g.: severe rusting, apparent structural <br />defects), or if it begins to leak, the material shall be transferred immediately to <br />another compatible container. The old container as well as the spillage will be <br />handled as a waste. <br />D. Different wastes shall not be placed into the same container. Mixing of different <br />types of waste may result in a chemical reaction or other undesirable results. <br />Before any unknown waste is combined, contact your DHM for help. Disposal <br />sites may not accept mixed waste even if it is compatible, which will cause <br />higher disposal costs. <br />July 2018 <br />
