POTENTIAL HEALTH EFFECTS

ACUTE HEALTH EFFECTS

SWALLOWED

  Severely toxic effects may result from the accidental ingestion of the material; animal experiments indicate that ingestion of less than 5 gram may be fatal or may produce serious damage to the health of the individual.  

EYE

  Although the material is not thought to be an irritant, direct contact with the eye may produce transient discomfort characterized by tearing or conjunctival redness (as with windburn).  

SKIN

  The material is not thought to produce adverse health effects or skin irritation following contact (as classified using animal models). Nevertheless, good hygiene practice requires that exposure be kept to a minimum and that suitable gloves be used in an occupational setting.  Toxic effects may result from skin absorption.  

INHALED

  The material is not thought to produce adverse health effects or irritation of the respiratory tract (as classified using animal models). Nevertheless, good hygiene practice requires that exposure be kept to a minimum and that suitable control measures be used in an occupational setting.  Contact with water liberates toxic gases.  Inhalation of the vapor is hazardous and may even be fatal.  

CHRONIC HEALTH EFFECTS

  Principal routes of exposure are usually by.  inhalation.  skin contact/eye contact.  The effects of exposure are typical of those resulting due to exposure to  phosphine gas.  Inhalation of phosphine may result in pain in the region of the diaphragm,  feeling of coldness, weakness, vertigo, nausea, vomiting, dyspnea, bronchitis,  oedema, lung damage, convulsions, coma and possible death. [Merck]  Breathing difficulties may be delayed several hours after exposure to  phosphine has ceased. [CHRIS]  Eye and skin contact may result in burns due to dermal moisture promoting  release of phosphine gas.  Ingestion may result in respiratory, cardiac, hepatic and renal involvement  due to rapid release of phosphine gas.
