Move the victim into fresh air. If breathing is difficult, give oxygen. If not breathing, give artificial respiration and consult a doctor immediately. Do not use mouth to mouth resuscitation if the victim ingested or inhaled the chemical.
Take off contaminated clothing immediately. Wash off with soap and plenty of water. Consult a doctor.
Rinse with pure water for at least 15 minutes. Consult a doctor.
Rinse mouth with water. Do not induce vomiting. Never give anything by mouth to an unconscious person. Call a doctor or Poison Control Center immediately.
Inhalation of dust causes irritation of nose and throat. Contact with eyes or skin causes irritation. Ingestion has been observed to cause tremors and muscle spasms in test animals. (USCG, 1999)
Basic treatment: Establish a patent airway. Suction if necessary. Watch for signs of respiratory insufficiency and assist ventilations if necessary. Administer oxygen by nonrebreather mask at 10 to 15 L/min. Monitor for pulmonary edema and treat if necessary . Anticipate seizures and treat if necessary . For eye contamination, flush eyes immediately with water. Irrigate each eye continuously with normal saline during transport . Do not use emetics. For ingestion, rinse mouth and administer 5 ml/kg up to 200 ml of water for dilution if the patient can swallow, has a strong gag reflex, and does not drool. Administer activated charcoal . Cover skin burns with dry, sterile dressings after decontamination . Hydrazine and Related Compounds
Extinguish with water, dry chemicals, foam or carbon dioxide.
Special Hazards of Combustion Products: Toxic nitrogen oxides are produced. (USCG, 1999)
Wear self-contained breathing apparatus for firefighting if necessary.
Avoid dust formation. Avoid breathing mist, gas or vapours.Avoid contacting with skin and eye. Use personal protective equipment.Wear chemical impermeable gloves. Ensure adequate ventilation.Remove all sources of ignition. Evacuate personnel to safe areas.Keep people away from and upwind of spill/leak.
Prevent further spillage or leakage if it is safe to do so. Do not let the chemical enter drains. Discharge into the environment must be avoided.
Ventilate area of spill or leak. Collect for reclamation, or absorb in vermiculite, dry sand, earth, or a similar material.
Handling in a well ventilated place. Wear suitable protective clothing. Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Use non-sparking tools. Prevent fire caused by electrostatic discharge steam.
De-Cut, Fair Plus, Super De-sprout have indefinite shelf life and should be stored at room temp.

Ensure adequate ventilation. Handle in accordance with good industrial hygiene and safety practice. Set up emergency exits and the risk-elimination area.
Wear tightly fitting safety goggles with side-shields conforming to EN 166(EU) or NIOSH (US).
Wear fire/flame resistant and impervious clothing. Handle with gloves. Gloves must be inspected prior to use. Wash and dry hands. The selected protective gloves have to satisfy the specifications of EU Directive 89/686/EEC and the standard EN 374 derived from it.
If the exposure limits are exceeded, irritation or other symptoms are experienced, use a full-face respirator.

Very stable to both acidic & basic hydrolysis.
MALEIC HYDRAZIDE can be decomposed by oxidizing agents. It can also be decomposed by strong acids. It forms water-soluble alkali-metal and amine salts. It is slightly acidic and may be titrated as a monobasic acid. Mild oxidation produces a compound which reacts instantly with dienes at -107° F to form crystalline derivatives. This chemical is slightly corrosive to iron and zinc. It is incompatible with pesticides that are highly alkaline in reaction. In the presence of heavy metal and iron, zinc, calcium and magnesium ions, sparingly-soluble salts are formed. (NTP, 1992)

If in presence of strong acid, maleic hydrazide acid may precipitate. Do not use concentrate through brass nozzles as the amine content may cause erosion.
When heated to decomposition it emits highly toxic fumes of /nitrogen oxides/.

Maleic hydrazide can serve as sole source of carbon & nitrogen for number of microorganisms & ... is very subject to bacterial decomp in soil .
An estimated BCF of 3 was calculated for maleic hydrazide(SRC), using a log Kow of -1.96 (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).
The reported Koc of maleic hydrazide was 264 for a clay soil, and 23 for a sand(1). Based on a classification scheme(2), these Koc values suggest that maleic hydrazide has very high to moderate mobility in soil(SRC). In a field experiment in which 5 and 10 kg/ha of maleic hydrazide were applied, the hydrazide did not migrate below a depth of 10 cm(3). This may be due to extensive biodegradation of maleic hydrazide(3). Maleic hydrazide was shown to bind to the clay component in Aiken clay loam where anion exchange is the predominant process(4). In a study of the adsorption of maleic hydrazide in 22 different soils, adsorption was most significantly correlated to specific surface area, clay content, and pH(5). The lack of correlation of adsorption with organic content of the soils may have been partly caused by the low organic content of the soils studied (<2%)(5). Adsorption of the herbicide ranged from high to low(5). Based upon the above information, maleic hydrazide may generally be expected to be mobile in soils with low clay content and relatively immobile in soils with high clay content. The mobility also may be affected by pH and specific surface area of the soils(SRC).

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.
