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. 

Concentrated wastes can result from bad product being made, unsalable byproducts, contamination of products, laboratory wastes, and previously mentioned pollution-abatement steps that concentrate the pollutants. Whatever their source, if recovery is impossible, they must be eliminated. The most common means are incineration or pyrolysis followed by landfill operations and/or compacting. As...

Interaction is exothermic, and if air is present, incandescence may occur with freshly prepared granular material. Admixture with oxygen causes a violent explosion [1], Soda-lime, used to absorb hydrogen sulfide, will subsequently react with atmospheric oxygen and especially carbon dioxide (from the solid coolant) with a sufficient exotherm in contact with moist paper wipes (in a laboratory waste bin) to cause ignition [2], Spent material should be saturated with water before separate disposal. Mixture analogous to soda-lime, such as barium hydroxide with potassium or sodium hydroxides, also behave similarly [1],... 

Other types of solid laboratory waste including used silica gel and charcoal should also be packed, labeled, and sent for disposal in a secure landfill. 

Labpack Generally refers to any small containers of hazardous waste in an overpacked drum, but not restricted to laboratory wastes.

Soda-lime, after absorbing hydrogen sulfide, exhibits a considerable exotherm (100°C) when exposed simultaneously to moisture and air, particularly with carbon dioxide enrichment, and has caused fires in laboratory waste bins containing moist paper wipes. Saturation with water and separate disposal in sealed containers is recommended.

Despite data reporting occupational exposure that can occur through the handling and processing of mycotoxins and manipulation in the laboratory, little focus has been placed on those issues, and precautions to be undertaken in the laboratory are rarely mentioned in papers dealing with the analysis of mycotoxins. As far as the latter issue is concerned, safety measures include precautions in handling mycotoxins, and the decontamination and destruction of laboratory wastes. In addition, it is necessary to institute precautions aimed at avoiding the loss of accuracy.

Due to the ease of formation of third phase with CMPO, many literature reports are based on the use of the mixture of 0.2 M CMPO + 1.2 M TBP as the solvent (63). This mixture has also been used in the TRUEX process recommended for the partitioning of minor actinides from HLW. Some applications of CMPO for the separation of Pu include its recovery from assorted laboratory wastes and oxalate supernatant (64, 65).
