![]() The initial responsibility for implementing this hierarchy rests with trained laboratory personnel. As suggested in previous chapters, there is a strategic hierarchy for managing chemicals and waste to accomplish these objectives. The best strategy for managing laboratory waste aims to maximize safety and minimize environmental impact, and considers these objectives from the time of purchase. This chapter presents methods for the management and ultimate disposal of laboratory waste that may present chemical hazards, as well as those multihazardous wastes that contain some combination of chemical, radioactive, and biological hazards. Control panels are normally located on the units, but can be remotely mounted anywhere in the lab.8.B.2.1 Characterization for Off-Site ManagementĨ.B.2.2 Identification Responsibilities of All Laboratory PersonnelĨ.B.2.4 In-Laboratory Test Procedures for UnknownsĨ.B.3.1 Definition of Characteristic WasteĨ.B.3.3 Determining the Regulatory Status of a WasteĨ.B.4.1 Accumulation of Waste at the Location of GenerationĨ.B.4.2 Accumulation of Waste in a Central AreaĨ.B.4.3 Special Regulations for Laboratories at Academic InstitutionsĨ.B.5 Disposal of Nonhazardous and Nonregulated WasteĨ.B.7 Monitoring Waste Services, Transport, and Off-Site Treatment and DisposalĨ.B.7.1 Preparation for Off-Site Treatment or Disposal of WasteĨ.B.7.2 Choice of Transporter and Disposal FacilityĨ.C.1.4 Commercial Disposal Services for Mixed WasteĨ.C.2.1 Disposal of Chemically Contaminated Animal TissueĨ.C.2.2 Sewer Disposal of Chemical–Biological Liquids The units can be located under counters or in cabinets. They can include collection tanks with pumps or be located near floor drains for gravity discharge into the sewer. LabDELTA units are small enough to be located in the laboratory itself. The units can be monitored locally with alarm lights, or remotely on a PC using web-based TCP/IP communications or modem-to-modem dial-up. Pump options incorporating high level alarms and automatic shut-offs are available to transfer untreatable waste to drums. Solvent waste, acid waste, and most lab liquid wastes are handled automatically. Wastech's LabDELTA™ laboratory waste treatment units are quiet, sealed to eliminate vapors, and designed to be vented to building systems. Wastech Controls has been supplying waste treatment solutions since 1987, and brings this design experience into the lab with reliable designs and durable components such as pH sensors and pH controllers. PP heat exchanger at bottom of reaction tank. ![]() The units are small and compact, fabricated of polypropylene, with drip pans or double-containment as requested, and include all sensors and controllers. Using various system designs including two-stage neutralization, limestone pretreatment, or packaged chillers with PVDF or Telfon heat exchangers, Wastech Controls treats the waste safely and prepares it for dumping into the sewer. Accidents from exothermic reactions, spills, burns and glass breakage are eliminated. Other systems handle heavy metals, fluoride reduction, and pH adjustment for caustic fluids, automatically and without risk to lab personnel. ![]() ![]() Acid waste neutralization (AWN) including strong acid neutralization (0-2 pH) is typical. Complete packages are available in either 2, 4 or 6 gallon batch designs or 1, 2 or 3 gpm continuous designs with complete controls, including communication options for alarm reporting. These are ideal as school laboratory waste treatment systems. LabDELTA™ from Wastech Controls solves laboratory waste treatment problems with small-volume, automated systems. LabDELTA™ from Wastech automates laboratory liquid processesįrom waste treatment to dispensing and chemical mixing. Solves Laboratory Waste Treatment Problems
