Cleanup Methods
Hydrazine removal from nuclear power plant wastewater using activated carbon and copper ion catalysts.
In the event of a spill, remove all ignition sources, soak up the hydrazine with a spill pillow or absorbent material, place in an appropriate container, and dispose of properly. Evacuation and cleanup using respiratory protection may be necessary in the event of a large spill or release in a confined area.
Spill or leak procedures: Eliminate all ignition sources. Approach release from upwind. Use water spray to cool & disperse vapors, protect personnel, & dilute spills to form nonflammable mixtures. Control runoff & isolate discharged material for proper disposal.
Environmental considerations: Land Spill: Dig a pit, pond, lagoon, holding area to contain liquid or solid material. /SRP: If time permits, pits, ponds, lagoons, soak holes, or holding areas should be sealed with an impermeable flexible membrane liner./ Dike surface flow using soil, sand bags, foamed polyurethane, or foamed concrete. Absorb bulk liquid with fly ash, cement powder, or commercial sorbents.

Oxidizers, hydrogen peroxide, nitric acid, metallic oxides, acids (Note: Can ignite SPONTANEOUSLY on contact with oxidizers or porous materials such as earth, wood, & cloth).
Hydrazine ignites in contact wiht chlorine.
Hydrazine is decomposed explosively by chromates & chromic anhydride.
Hydrazine reacts vigorously with cupric oxide.
Spontaneous ignition occurs when /fluorine & hydrazine/ are mixed.
The catalytic decomposition of hydrazine in the presence of Raney nickel may be vigorous at room temp.

Other Preventative Measures
If material not on fire and not involved in fire: Keep material out of water sources and sewers. Attempt to stop leak if without undue personnel hazard. Use water spray to knock-down vapors. /Hydrazine, aqueous solution/
If material not on fire and not involved in fire: Keep sparks, flames, and other sources of ignition away. Keep material out of water sources and sewers. Build dikes to contain flow as necessary. Attempt to stop leak if without undue personnel hazard. Use water spray to diperse vapors and dilute standing pools of liquid.
SRP: Contaminated protective clothing should be segregated in such a manner so that there is no direct personal contact by personnel who handle, dispose, or clean the clothing. Quality assurance to ascertain the completeness of the cleaning procedures should be implemented before the decontaminated protective clothing is returned for reuse by the workers. Contaminated clothing should not be taken home at end of shift, but should remain at employee's place of work for cleaning.
Personnel protection: Avoid breathing vapors. Keep upwind. ... Avoid bodily contact with the material. ... Do not handle broken packages unless wearing appropriate protective equipment. Wash away any material which may have contacted the body with copious amounts of water or soap and water. /Hydrazine, anhydrous; hydrazine, aqueous solution/
SRP: The scientific literature for the use of contact lenses in industry is conflicting. The benefit or detrimental effects of wearing contact lenses depend not only upon the substance, but also on factors including the form of the substance, characteristics and duration of the exposure, the uses of other eye protection equipment, and the hygiene of the lenses. However, there may be individual substances whose irritating or corrosive properties are such that the wearing of contact lenses would be harmful to the eye. In those specific cases, contact lenses should not be worn. In any event, the usual eye protection equipment should be worn even when contact lenses are in place.

Disposal Methods
Generators of waste (equal to or greater than 100 kg/mo) containing this contaminant, EPA hazardous waste number U133, must conform with USEPA regulations in storage, transportation, treatment and disposal of waste.
Hydrazine is a waste chemical stream constituent which may be subjected to ultimate disposal by controlled incineration with facilities for effluent scrubbing to abate any ammonia formed in the combustion process.
Hydrazine is a potential candidate for liquid injection incineration with a temperature range of 650 to 1600 deg C and residence times of 0.1 to 2 seconds. Also a potential candidate for rotary kiln incineration with a temperature range of 820 to 1,600 deg C and residence times of seconds for liquids and gases; hours for solids. Also a potential candidate for fluidized bed incineration with a temperature range of 450 to 980 deg C and residence times of seconds for liquids and gases; longer for solids.
Recommendable method: Incineration. Peer-review: Dilute well with alcohol, hydrocarbon solvent before burning. Concentrated hydrazine may explode if heated. Hydrazine is a powerful reductant but should be well diluted prior to oxidizing. (Peer-review conclusions of an IRPTC Expert Consultation (May 1985))
PRECAUTIONS FOR "CARCINOGENS": There is no universal method of disposal that has been proved satisfactory for all carcinogenic compounds & specific methods of chem destruction ... published have not been tested on all kinds of carcinogen containing waste. ... summary of avail methods & recommendations ... /given/ must be treated as guide only. /Chemical Carcinogens/
PRECAUTIONS FOR "CARCINOGENS": ... Incineration may be only feasible method for disposal of contaminated laboratory waste from biological expt. However, not all incinerators are suitable for this purpose. The most efficient type ... is probably the gas fired type, in which a first stage combustion with a less than stoichiometric air:fuel ratio is followed by a second stage with excess air. Some ... are designed to accept ... aqueous & organic solvent solutions, otherwise it is necessary ... to absorb soln onto suitable combustible material, such as sawdust. Alternatively, chem destruction may be used, esp when small quantities ... are to be destroyed in laboratory. /Chemical Carcinogens/
PRECAUTIONS FOR "CARCINOGENS": HEPA (high efficiency particulate arrestor) filters ... can be disposed of by incineration. For spent charcoal filters, the adsorbed material can be stripped off at high temp & carcinogenic wastes generated by this treatment conducted to & burned in an incinerator. ... LIQUID WASTE: ... Disposal should be carried out by incineration at temp that ... ensure complete combustion. SOLID WASTE: Carcasses of lab animals, cage litter, & misc solid wastes ... should be disposed of by incineration at temp high enough to ensure destruction of chem carcinogens or their metabolites. /Chemical Carcinogens/
PRECAUTIONS FOR "CARCINOGENS": ... Small quantities of ... some carcinogens can be destroyed using chem reactions ... but no general rules can be given. ... As a general technique ... treatment with sodium dichromate in strong sulfuric acid can be used. The time necessary for destruction ... is seldom known ... but 1-2 days is generally considered sufficient when freshly prepd reagent is used. ... Carcinogens that are easily oxidizable can be destroyed with milder oxidative agents, such as saturated soln of potassium permanganate in acetone, which appears to be a suitable agent for destruction of hydrazines or of compounds containing isolated carbon-carbon double bonds. Concn or 50% aqueous sodium hypochlorite can also be used as an oxidizing agent. /Chemical Carcinogens/
PRECAUTIONS FOR "CARCINOGENS": Carcinogens that are alkylating, arylating or acylating agents per se can be destroyed by reaction with appropriate nucleophiles, such as water, hydroxyl ions, ammonia, thiols, & thiosulfate. The reactivity of various alkylating agents varies greatly ... & is also influenced by sol of agent in the reaction medium. To facilitate the complete reaction, it is suggested that the agents be dissolved in ethanol or similar solvents. ... No method should be applied ... until it has been thoroughly tested for its effectiveness & safety on material to be inactivated. For example, in case of destruction of alkylating agents, it is possible to detect residual compounds by reaction with 4-(4-nitrobenzyl)-pyridine. /Chemical Carcinogens/
Neutralization of hydrazine fuels with hypochlorite is a recommended procedure for the treatment of fuel spills prior to disposal. Previous research has shown that incomplete reaction of hypochlorite with the methylated hydrazine fuels monomethylhydrazine and unsymmetrical dimethylhydrazine leads to a wide variety of byproducts, including N-nitrosoamines, which are believed to be highly carcinogenic. The results presented in this paper were obtained as part of a program to assess the environmental implications of using the hypochlorite method for the treatment and disposal of hydrazine fuel spills. The fuels examined were hydrazine, monomethylhydrazine, unsymmetrical dimethylhydrazine and Aerozine-50. The neutralization products were determined under experimental conditions comparable to those expected for actual spills. The effects of varying the temperature and the pH as well as of aging the final reaction mixture were determined. Quantitative measurements of nitrosoamines produced are presented. Major and environemntally significant minor products were identified using gas chromatography /mass-spectrometry.
Liquid injection or fluidized bed incineration methods are acceptable disposal methods ... .
