50 ppm; NIOSH considers hydrazine to be a potential occupational carcinogen.

Decomposes . This produces ammonia, hydrogen and nitrogen oxides. This generates fire and explosion hazard. The substance is a strong reducing agent. It reacts violently with oxidants. The substance is a medium strong base. Reacts violently with acids, many metals, metal oxides and porous materials. This generates fire and explosion hazard. Air or oxygen is not required for decomposition.

Hydrazine vapor is exceptionally hazardous in that once it is ignited it will continue to burn by exothermic decomposition in complete absence of air or other oxidant.HYDRAZINE is a powerful reducing agent. May ignite spontaneously if mixed with hydrogen peroxide or with nitric acid. Decomposes with flame on contact with many metallic oxide surfaces [Haz. Chem. Data(1966)]. While boiling a piece of polyester fiber in hydrazine in a glass beaker, a technician put a somewhat rusty pair of metal tweezers into the hydrazine, which then ignited [MCA Case History 1893 (1973)]. Forms explosive metal hydrazides when mixed with alkali metals in presence of ammonia [Mellor 8, Supp. 2:95(1967)]. During the measurement of the shock sensitivity of a mixture containing hydrazine, a drop of the mixture fell on a tetryl explosive. The tetryl immediately burst into flames [ASESB 105]. Ignites spontaneously if mixed with nitrous oxide [Mellor 8, Supp. 2:214(1967)]. Reacts explosively with potassium and sodium dichromate [Mellor 11:234(1946-1947)].

NTP: Reasonably anticipated to be a human carcinogen

Information is not available on the reproductive or developmental effects of hydrazine in humans. Data regarding developmental effects in animals are limited to a study in which hydrazine injected into pregnant rats resulted in fetotoxicity including increased fetal and neonatal mortality. (,10) Inhalation of hydrazine for a year resulted in effects to the ovaries, endometrium, and uterus in female rats and to the testes in male hamsters. (10)

The substance is corrosive to the eyes, skin and respiratory tract. Inhalation may cause lung oedema, but only after initial corrosive effects on eyes and/or airways have become manifest. Corrosive on ingestion. The substance may cause effects on the liver and central nervous system. Exposure could cause death.

Repeated or prolonged contact may cause skin sensitization. The substance may have effects on the liver, kidneys and central nervous system. This substance is possibly carcinogenic to humans.

A harmful contamination of the air can be reached very quickly on evaporation of this substance at 20°C.

Pure cultures of Azotobacter vinelandii are capable of metabolizing hydrazine to three carboxylic acids related to 3,4-dihydropyridazinone-5-carboxylic acid and ammonia and nitrogen gas(1) and unidentified, acid-labile compounds(2). The degradation of hydrazine hydrate in river water follows 1st order reaction kinetics(3). The degradation rate increases with increasing temperature, dissolved oxygen, and the presence of microorganisms at pH values of 6-8(3). Hydrazine at 500 mg/l, present in a wastewater mixture of other hydrazine compounds, was incubated with an inoculum prepared from a trickling filter plant; following a 24 hour lag period, this mixture of compounds was readily biodegraded as measured by oxygen uptake(4). No specific information on the fate of hydrazine alone was available in this study(4).

An estimated BCF of 3 was calculated for hydrazine(SRC), using a log Kow of -2.07(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low (SRC). Bioconcentration in guppies was studied using both "hard" (440 mg/L CACO3) and "soft" (22 mg/L CACO3) water (4). Little uptake was noted in the soft water experiments, but mild bioconcentration was observed in the experiments conducted using hard water(4). After 96 hours, the concentration of hydrazine in guppies was about 144 ug/g(4).

The Koc of hydrazine is estimated as 2(SRC), using a log Kow of -2.07(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that hydrazine is expected to have very high mobility in soil(SRC). Hydrazine is a weak base (pKa= 7.96); at pH values well below the pKa, hydrazine exists primarily as the protonated form and can take part in cation exchange reactions(4). The nature and extent of hydrazine adsorption by clays and soils is very dependent on suspension pH and on the types of surface functional groups present on the solid matrix. Under acidic conditions, pH 4.0, 99.9% of the hydrazine is present as the protonated species and should be able to readily replace Na+ from exchange sites(4). Under alkaline conditions, pH 8.0, approximately 50% of the hydrazine is protonated and 50% is in neutral form. The primary mechanism of hydrazine adsorption in a montmorillonite clay suspension was cation exchange, both at pH 4 and 8; adsorption of hydrazine was lower at the higher pH value(4). The main mechanism for hydrazine retention at pH 4 and at low hydrazine concentrations in the upper Arrendondo soil horizon (fine sand) was also cation exchange. At higher concentrations more than 60% of the hydrazine interacted with a different type of binding site, possibly with organic-surface functional groups such as carbonyl groups(4). Under alkaline conditions, using upper horizon Arrendondo soil, (at pH 8.0) hydrazine was adsorbed more readily than at pH 4(4).

The material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. Do not discharge to sewer systems.

Containers can be triply rinsed (or equivalent) and offered for recycling or reconditioning. Alternatively, the packaging can be punctured to make it unusable for other purposes and then be disposed of in a sanitary landfill. Controlled incineration with flue gas scrubbing is possible for combustible packaging materials.
