POTENTIAL HEALTH EFFECTS

ACUTE HEALTH EFFECTS

SWALLOWED

  Toxic effects may result from the accidental ingestion of the material; animal experiments indicate that ingestion of less than 40 gram may be fatal or may produce serious damage to the health of the individual.  The material can produce chemical burns within the oral cavity and gastrointestinal tract following ingestion.  Considered an unlikely route of entry in commercial/industrial environments.  

EYE

  The material can produce chemical burns to the eye following direct contact. Vapors or mists may be extremely irritating.  If applied to the eyes, this material causes severe eye damage.  The material may produce moderate eye irritation leading to inflammation. Repeated or prolonged exposure to irritants may produce conjunctivitis.  

SKIN

  The material can produce chemical burns following direct contactwith the skin.  Toxic effects may result from skin absorption.  Exposure limits with "skin" notation indicate that vapor and liquid may be absorbed through intact skin. Absorption by skin may readily exceed vapor inhalation exposure. Symptoms for skin absorption are the same as for inhalation. Contact with eyes and mucous membranes may also contribute to overall exposure and may also invalidate the exposure standard.  The material may cause skin irritation after prolonged or repeated exposure and may produce on contact skin redness, swelling, the production of vesicles, scaling and thickening of the skin.  

INHALED

  If inhaled, this material can irritate the throat andlungs of some persons.  Inhalation hazard is increased at higher temperatures.  If exposure to highly concentrated solvent atmosphere is prolonged this may lead to narcosis, unconsciousness, even coma and possible death.  The material may produce respiratory tract irritation, and result in damage to the lung including reduced lung function.  

CHRONIC HEALTH EFFECTS

  There is ample evidence that this material can be regarded as being able to cause cancer in humans based on experiments and other information.  

  Principal routes of exposure are usually via inhalation and skin  contact/absorption. Hydrazine is a strong irritant and is corrosive in high  concentrations via all routes of exposure, in addition hydrazine exerts a  pronounced systemic effect via any route of exposure. Symptoms include  nausea dizziness, headache, and central nervous system excitability.  Central nervous system poisoning may lead to convulsions, and, in severe  cases, respiratory arrest and death. Chronic and systemic symptoms of  exposure include damage to the liver, kidney and blood producing system.  Hydrazine has also been reported as an allergen. Inhalation of high  concentrations may cause pulmonary oedema. (Sax, ILO Encyclopaedia)
