Sampling and analysis of unknowns are expensive to analyze prior to disposal; (3) Formation of a corrosive product that may result in incompatibility with the container and possibly cause the container to degrade and leak; 14.2.3 Mixing Wastes 14.2.3.1 Rules a. When mixing similar wastes, the following general compatibility rules shall be followed: (1) Separate highly toxic and less toxic wastes; (2) Separate halogenated and non-halogenated wastes (halogens are materials containing bromine, chlorine, fluorine, iodine, or astatine); (3) Separate liquids and solids; (4) Separate metal containing wastes from non-metal containing wastes (metals of specific concern are arsenic, barium, chromium, cadmium, lead, mercury, selenium, or silver); (5) Separate oils from other wastes; and (6) Separate waste types (flammables, corrosives, oxidizers, poisons, cyanides and sulfides, water or air reactives, etc.) from each other. 14.2.3.2 Waste Compatibility List More specific information can be found in the Waste Compatibility List developed by the U.S. EPA, provided in Appendix C. 14.2.4 Log Documentation a. Laboratories shall keep a separate log for each waste accumulation container, and include the following documentation for each addition: (1) The date waste was added to the container; (2) The name of person adding the waste; (3) The amount of waste added; (4) A detailed description of the added waste specifying the chemical name (not product name) and the percentages of each chemical in mixtures; and (5) A copy of the log accompanying the container when picked up for disposal.

JSC Environmental Compliance Procedural Requirements JPR No. 8550.1A XXXX.X Effective Date: Johnson Space Center • Environmental Compliance Program Expiration Date: Expiration Date: Page Number 3/25/2011 3/25/2016 [Leave Blank] Page 109 of 123 14.3 Container Type a. The container must be compatible with the type of waste it will contain. For example, do not place acid in a steel drum. The acid will corrode the steel container and cause a possible leak or spill. Glass containers shall not be used when plastic or other unbreakable materials are appropriate and available. b. Regardless of container type, all employees shall comply with all the waste accumulation requirements in Chapter 3, Managing Industrial Solid Waste, including: (1) Containers shall be kept closed at all times, except when adding wastes; (2) Each container shall be labeled with the name or description of the contents; (3) The exterior of the container shall be clean, and (4) The container shall be in good condition (not leaking, excessively corroded, or otherwise show evidence of deterioration; contact the EO if the container requires over packing. 14.4 Container Size Select the smallest practical size of container in order to minimize the amount of waste that you accumulate before calling for pickup and disposal. Waste containers come in different sizes and materials. 5-gallon polyethylene, 55-gallon polyethylene, and 55-gallon steel containers are available by calling Facilities Work Control. 14.5 Accumulation Location 14.5.1 Outside Waste Accumulation Wastes should be accumulated in a location that is secure and appropriate. Waste containers should be stored in locations protected from the weather when possible. Drums will rust over time, labels will fade in sunlight, and any waste that may be on the exterior of the container will get into storm water during rain. If waste is stored outdoors and in large quantities (55 gallons or more), containment will need to be provided that will hold the waste and any rainwater if the container should leak. More information on waste accumulation areas is provided in Chapter 3, Managing Industrial Solid Waste. 14.5.2 Vent Hoods Waste accumulation containers shall not be stored in vent hoods unless there is no other safe alternative. 14.6 Accumulation Time a. Wastes shall not be accumulated for more than 6 months. b. Laboratories shall not accumulate wastes for more than 3 months.
