May cause SENSITIZATION by skin contact.
Limited evidence of a carcinogenic effect.
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 to be non toxic. Considered an unlikely route of entry in commercial/industrial environments.
There is some evidence to suggest that this material can causeeye irritation and damage in some persons. The material may be irritating to the eye, with prolonged contact causing inflammation. Repeated or prolonged exposure to irritants may produce conjunctivitis.
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. Excessive use or prolonged contact may lead to defatting, dryingand irritation of sensitive skin.
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. Not normally a hazard due to non-volatile nature of product. Inhalation of vapor is more likely at higher than normal temperatures.
There has been concern that this material can cause cancer or mutations, but there is not enough data to make an assessment. Skin contact with the material is more likely to cause a sensitization reaction in some persons compared to the general population.
Considered to be non toxic. During the curing period small amounts of methanol may be liberated from the crosslinking/termination process. Swallowing large amounts may produce nausea and have a laxative effect. When heated at high temperatures inhalation of fumes and oxidation products from methyl silicones can be irritating and toxic.
