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.
This material can cause eye irritation and damage in some persons.
This material can cause inflammation of the skin oncontact in some persons. Skin contact is not thought to have harmful health effects, however the material may still produce health damage following entry through wounds, lesions or abrasions.
Inhalation may produce health damage*. If inhaled, this material can irritate the throat andlungs of some persons.
Principal routes of exposure are usually by inhalation of generated dust and skin contact / absorption of the material. Sodium borates, a principal component of the developer, are absorbed slowly through skin intact and very rapidly through broken skin, but not to a sufficient extent to cause poisoning. Chronic absorption may lead to the deposition of boron in the liver, brain, bone and adipose tissue. Chronic dust inhalation may lead to inflammation of the respiratory mucous membranes and conjunctivitis. (ILO Encyclopeadia) Ingestion of the material may result in rash, vomiting, diarrhoea, depression of circulation, subnormal temperature, profound shock and coma.
