Flammables disposal

Spill Disposal In treatment of spills or wastes the suppression of vapors is the first concern and the aquatic toxicity to plants, fish, and microorganisms is the second. Normal procedures for flammable Hquids should also be carried out. 

Resource Conservation and ecoveTy Jict. The RCRA focuses on the proper disposition of waste from industrial processes. The interface to printing ink is primarily solvents, which can be flammable, and ingredients in ink that can contribute to the presence of certain heavy metals. The proper interface is the safe disposal of waste inks, but is often confused with disposal of printing matter. 

Higher dimeric ketenes are flammable but have higher flash points and are less reactive than diketene. Almost no data are available. Diketene can be disposed of by incineration, preferably after dilution with an inert solvent such as toluene. Higher ketene dimers can also be incinerated. 

An elementary introduction to chemistry is given in Chapter 3 this serves only to provide background and for more advanced consideration reference will be necessary to specific text books, e.g. as listed in the Bibliography. A brief discussion of the relevance of physicochemical principles to hazard identification is given in Chapter 4. Relevant toxic and flammable properties, and summaries of appropriate precautions to cater for them during handling, use and disposal, are provided in Chapters 5 and 6, respectively. Reactive hazards are discussed in Chapter 7. The special problems with cryogenic materials and chemicals under pressure, typified by compressed...

Waste treatment prior to disposal may introduee phase ehanges whieh result in quite different pollution eontrol eonsiderations. For example, the gases generated by ineineration of a solid waste ean be serubbed with liquid in order to meet an aeeeptable diseharge eriterion henee, in addition to ash for disposal, a liquid effluent stream is produeed and requires treatment. Other waste treatment proeesses may result in the liberation of flammable or toxie gaseous emissions as exemplified in Table 16.5. 

Landfill disposal of certain categories of solid waste may result in gas generation, mainly methane, and a highly polluted leachate. The methane may be drawn off, to avoid a flammable hazard on- or off-site. The leachate is pumped off for treatment. 

Listing of solid wastes, quantities, analyses and physical form (e.g. solid, slurry, suspension, sludge) toxicity and flammability. Checking the reliability and legality of waste disposal options, including any transportation offsite. Record keeping. 

The purpose of the facilities described in this chapter is to provide for safe handling of various drainage materials and emergency streams, so that they may be safely routed to the sewer, tankage, flare, or other appropriate destination. Drainage systems specified herein ensure that flammable or toxic materials may be disposed of without hazard of fire or injury when equipment is taken out of service. Also described are systems to handle process water drawoffs, cooling water, and other aqueous effluent streams which may be contaminated with hydrocarbons, and which could otherwise create hazardous conditions if they were discharged directly to the sewer. 

Waste disposal systems containing flammable, corrosive, or toxic materials should be at least 250 feet from plant equipment.

The laboratory operator must make a careful examination of all wastes that will be generated and, from this, work up a waste disposal system. Some wastes may be compatible and could be disposed of together. Others could react and thus cause problems. Flammables must be given special attention. Certain biological wastes may be very hazardous even in small quantities. Special rules apply to radioactive materials, even in the small amounts used for investigative purposes. 

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.
