Very toxic to aquatic organisms, may cause long- term adverse effects in the
aquatic environment.

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.  Not normally a hazard due to physical form of product.  Considered an unlikely route of entry in commercial/industrial environments.  

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.  Bare unprotected skin should not be exposed to this material.  Perspiration or moisture on the skin increases particle adhesion and possible abrasion so may result increased irritation.  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.  Reactions may not occur on exposure but response may be delayed with symptoms only appearing many hours later.  

CHRONIC HEALTH EFFECTS

  Principal routes of exposure are usually by inhalation of generated dust, inhalation of vapor given off by material that has become wet or damp and skin contact with the material.  The effects of exposure are typical of those resulting due to exposure to  phosphine gas.  Chronic phosphine poisoning is said to resemble chronic phosphorus  poisonings which produces stomach pains, vomiting and diarrhoea.  Chronic ingestion may produce systemic poisoning characterised by cachexia  (general ill-health and malnutrition), anaemia, bronchitis, and necrosis  of the mandible, the so-called "phossy" or Lucifer's" jaw. Other bones may  also be involved as demonstrated by chronic systemic administration to  animals which produces dense growth lines in all extremities proximal to  the epiphyses (phosphoschicht).
