Storage waste containers

It is important to keep the amount of potentially hazardous waste in the laboratory to a minimum at all times. Periodically, contents of the laboratory waste containers will be transferred to appropriate containers for final disposal. These must be stored in a safe location, often outdoors, while awaiting pick-up by a disposal service. There will be local restrictions for such storage. A locked storage area may be needed, for example, to prevent unauthorized access to hazardous materials. The fire department niiay set strict limits as to how much flammable material may be present. All containers must be marked with contents, and the storage area will no doubt require warning signs. 

Radioactive wastes are usually stored in underground tanks or in temporary storage at reactor sites for recycling or disposal (Whicker and Schultz 1982a). For low-level wastes, containment and isolation are the preferred disposal options, including burial, hydraulic injection into deep geological strata, and ocean disposal (Table 32.10). Options for the disposal of high-level wastes include... 

A storage tank contains water contaminated with a small quantity of a soluble hazardous waste material. The tank is 3 m in diameter and 6 m high. At the current time the liquid height is within 1 m of the top of the tank. 

Hexachloroethane and waste containing hexachloroethane are classified as hazardous wastes by EPA. Generators of waste containing this contaminant must conform to EPA regulations for treatment, storage, and disposal (see Chapter 7). Rotary kiln or fluidized bed incineration methods are acceptable disposal methods for these wastes. Underground injection may also be used (HSDB 1995). 

Hexane enters the air, water, and soil during its manufacture and use. Wastes containing //-hexane are sometimes disposed of in landfills. //-Hexane can enter the environment from these landfills. //-Hexane also enters the environment from accidental spills during transport and leaks from storage containers. 

A liquid swine manure sample collected from a waste storage basin contained benzoic acid at a concentration of 4.0 mg/L (Zahn et al., 1997). 

Hazardous waste must be packaged in accordance with DHS and Department of Transportation (DOT) requirements prior to shipment to a treatment, storage and/or disposal facility. Marking and labeling must also be in accordance with DOT guidelines. A hazardous waste label must be affixed to all hazardous waste containers. 

Significant quantities of mixed low-level waste have been generated and are in storage at more than 40 DOE sites, including national laboratories and naval shipyards. These wastes contain materials listed as hazardous or having hazardous characteristics under RCRA and wastes that are considered hazardous under TSCA (1976). At the end of 1994, DOE sites had in storage 91,000 metric tons of... 

The basic components of a high-performance liquid chromatographic system are shown in Figure 3.1. The instrument consists of (a) eluent containers for the mobile phase, (b) a pump to move the eluent and sample through the system, (c) an injection device to allow sample introduction, (d) a column(s) to provide solute separation, (e) a detector to visualize the separated components, (f) a waste container for the used solvent, and finally (g) a data collection device to assist in interpretation and storage of results.
