inhalation.
Toxic by inhalation and if swallowed.
Toxic to aquatic organisms, may cause long- term adverse effects in the aquatic
environment.

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.  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.  

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.  

CHRONIC HEALTH EFFECTS

  Inhaling this product is more likely to cause a sensitization reaction in some persons compared to the general population.  Skin contact with the material is more likely to cause a sensitization reaction in some persons compared to the general population.  There is sufficient evidence to suggest that this materialdirectly causes cancer in humans.  Based on experiments and other information, there is ample evidence to presume that exposure to this material can cause genetic defects that can be inherited.  Ample evidence exists from experimentation that reduced human fertility is directly caused by exposure to the material.  Ample evidence exists, from results in experimentation, that developmental disorders are directly caused by human exposure to the material.  

  The material is considered to be harmful by all exposure routes.  Principal routes of exposure are usually by skin contact/absorption, skin contact and inhalation of vapor.  One ingredient of the product has caused skin sensitization reactions, shown as localized reddening and hives, or may produce respiratory sensitization characterized by asthma-  like symptoms and runny nose.  Health problems mainly relate to pentavalent arsenic and hexavalent  chromium and appear in the treating process rather than the treated timber.  Arsenic poisoning may result from ingestion, or inhalation of mists,  spray or contaminated dust.  Long-term exposure to arsenic and its inorganic salts may produce loss of appetite, nausea and vomiting, low fever, persistent headache, pallor, weakness and phlegm. Skin effects include redness, eczema, pigmentation, diffuse hair loss, scaling of the palms and soles, sloughing, brittle nails, white lines or bands on the nails, loss of hair and nails, and localized swelling. Kidney damage can occur and liver enlargement with jaundice may develop into cirrhosis (hardening of the liver), with fluid in the abdomen. Nervous system effects involving the extremities (numbness, tingling, burning pain, weakness, inco-ordination) may also occur. Arsenic is well-known to cause cancer in humans.  Symptoms usually start a few weeks after the acute poisoning and recovery  is slow. Arsenic is a cumulative poison. [ILO Encyclopedia].  BE AWARE: Repeated minor exposures with only mild symptoms may have serious cumulative poisoning effect.  Workers in treatment plants or who handle wet CCA treated timber, should  be provided with regular medical checks, with determination of urinary  arsenic and chromium levels. [Manufacturer].
