4.1 “Stand-alone” laboratories rarely generate or handle large volumes of hazardous substances. However, the safe handling and disposal of these substances is still a matter of concern. Since the promulgation of the Resource Conservation and Recovery Act (RCRA) of 1976, more attention has been given to the proper handling and disposal of such materials. States may adopt more stringent requirements; information on this may be found along the path EPA Home > Wastes > Regions/States/Tribes > RCRA State Authorization > Data, Charts and Graphs (STATS) > State/Regional. To keep track of this, EPA classifies state regulatory language as (1) authorized, (2) procedural/enforcement, (3) broader in scope, and (4) unauthorized, and it publishes notices concerning the first three in the Federal Register.
4.2 Laboratory management should designate an individual who will be responsible for waste disposal and must review the RCRA guidelines, in particular:
40 CFR 261.3 - definition of a hazardous waste,
40 CFR 261.33 -specific substances listed as hazardous,
40 CFR 262 - generator requirements and exclusions, and proper shipping and manifesting procedures.
4.3 Because many laboratory employees could be involved in the proper treatment and disposal of laboratory chemicals and samples, it is recommended that a safety and training program be designed and presented to all regarding procedures to follow in the treatment and disposal of designated laboratory wastes. This recommendation is required in the United States by the EPA (40 CFR 265.16). For those who pack and ship, Hazardous Materials Shipper training is also required by DOT (49 CFR 172.203).5
4.4 If practical and economically feasible, it is recommended that all laboratory waste be either recovered, re-used, or disposed of in-house. However, should this not be the case, other alternatives are presented. This guide is intended only as a suggested organized method for classification, segregation, and disposal of chemical laboratory waste. A university can set up its own chemical distributor to take orders from departments, order in economical quantities, sell at prorated bulk price plus expenses, and take back what is unused. For an example of a university central facility for minimizing over-ordering, storing chemical packages between uses, and disposing of hazardous wastes, see the web site of the University of Vermont, especially Procedure 12: Laboratory Waste Pickup and RCRA Hazardous Waste Determination.
4.5 The handling of laboratory samples, especially those received in large numbers or quantities from a specific source, can often be accommodated by returning the material to the originator, for processing and potentially combining with larger quantities of the same material for recycling or disposal. Shipments of hazardous waste, including samples, are subject to RCRA regulations that do not apply to shipments of what is similar but not waste-like. A sample that was not a waste as received, and has not been contaminated or ......
包括:化学品空容器;过期与报废化学品;研究、试验等产生的化学废弃物;沾染化学品的实验器皿、耗材等废弃物;过期的样品等。 2.危险实验室废弃物 (hazardous waste) 列入国家危险废物名录或者根据国家规定的危险废物鉴別标准和鉴别方法认定的具有危险特性的实验室废弃物。 ...
3.废气的处理 实验室产生的少量废气ー般以通过通风装置直接排至室外。氯化氢、硫化氢等酸性气体,应用碱液吸收,如浓度很低则可以通过抽风设备排放到室外。毒性大的气体可以参考工业废气处理办法,用吸附、吸收、氧化、分解等方法处理后排放、废弃排放标准应符合GB14554和GB16297的相关要求。 ...
