POTENTIAL HEALTH EFFECTS

ACUTE HEALTH EFFECTS

SWALLOWED

  Although ingestion is not thought to produce harmful effects, the material may still be damaging to the health of the individual following ingestion, especially where pre-  existing organ (e.g. liver, kidney) damage is evident. Present definitions of harmful or toxic substances are generally based on doses producing mortality (death) rather than those producing morbidity (disease, ill-health). Gastrointestinal tract discomfort may produce nausea and vomiting. In an occupational setting however, ingestion of insignificant quantities is not thought to be cause for concern.  Considered an unlikely route of entry in commercial/industrial environments.  Ingestion may result in nausea, pain, vomiting. Vomit entering the lungs by aspiration may cause potentially lethal chemical pneumonitis.  

EYE

  This material can cause eye irritation and damage in some persons.  The liquid may produce eye discomfort and is capable of causing temporary impairment of vision and/or transient eye inflammation, ulceration.  The material may produce severe irritation to the eye causing pronounced inflammation. Repeated or prolonged exposure to irritants may produce conjunctivitis.  

SKIN

  Skin contact with the material may damage the health of the individual; systemic effects may result following absorption.  This material can cause inflammation of the skin oncontact in some persons.  The material may accentuate any pre-existing skin condition.  Toxic effects may result from skin absorption.  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

  Inhalation may produce health damage*.  If inhaled, this material can irritate the throat andlungs of some persons.  Inhalation hazard is increased at higher temperatures.  Inhalation of high concentrations of gas/vapor causes lung irritation with coughing and nausea, central nervous depression with headache and dizziness, slowing of reflexes, fatigue and inco-ordination.  The material may produce respiratory tract irritation, and result in damage to the lung including reduced lung function.  

CHRONIC HEALTH EFFECTS

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

  Principal routes of exposure are usually by skin contact/absorption and inhalation of vapor.  Prolonged or continuous skin contact with the liquid may cause defatting with drying, cracking, irritation and dermatitis following.  As with any chemical product, contact with unprotected bare skin; inhalation of vapor, mist or dust in work place atmosphere; or ingestion in any form, should be avoided by observing good occupational work practice.  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.
