Section 2 - HAZARDS IDENTIFICATION

CANADIAN WHMIS SYMBOLS

EMERGENCY OVERVIEW

May cause SENSITIZATION by skin contact.
Harmful by inhalation, in contact with skin and if swallowed.
Irritating to eyes and skin.
Toxic to aquatic organisms, may cause long- term adverse effects in the aquatic
environment.

POTENTIAL HEALTH EFFECTS

ACUTE HEALTH EFFECTS

SWALLOWED

  Accidental ingestion of the material may be harmful; animal experiments indicate that ingestion of less than 150 gram may be fatal or may produce serious damage to the health of the individual.  Considered an unlikely route of entry in commercial/industrial environments.  

EYE

  This material can cause eye irritation and damage in some persons.  

SKIN

  Skin contact with the material may be harmful; systemic effects may resultfollowing absorption.  This material can cause inflammation of the skin oncontact in some persons.  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.  

INHALED

  The material is not thought to produce respiratory irritation (as classified using animal models). Nevertheless inhalation of the material, especially for prolonged periods, may produce respiratory discomfort and occasionally, distress.  Inhalation hazard is increased at higher temperatures.  

CHRONIC HEALTH EFFECTS

  Skin contact with the material is more likely to cause a sensitization reaction in some persons compared to the general population.  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 routes 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)
