SECTION 11 TOXICOLOGICAL INFORMATION
Information on toxicological effects
Inhaled
The material is not thought to produce respiratory irritation (as classified by EC Directives using animal models). Nevertheless inhalation of
dusts, or fumes, especially for prolonged periods, may produce respiratory discomfort and occasionally, distress.
Acute silicosis occurs under conditions of extremely high silica dust exposure particularly when the particle size of the dust is small. It differs
greatly from classical silicosis both clinically and pathologically.
Ingestion
The material has
NOT
been classified by EC Directives or other classification systems as "harmful by ingestion". This is because of the lack of
corroborating animal or human evidence. 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 rather than those producing morbidity (disease, ill-health).
Skin Contact
The material is not thought to produce adverse health effects or skin irritation following contact (as classified by EC Directives 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.
Eye
Limited evidence exists, or practical experience suggests, that the material may cause eye irritation in a substantial number of individuals and/or
is expected to produce significant ocular lesions which are present twenty-four hours or more after instillation into the eye(s) of experimental
animals. Repeated or prolonged eye contact may cause inflammation characterised by temporary redness (similar to windburn) of the conjunctiva
(conjunctivitis); temporary impairment of vision and/or other transient eye damage/ulceration may occur.
Chronic
Harmful: danger of serious damage to health by prolonged exposure through inhalation.
Serious damage (clear functional disturbance or morphological change which may have toxicological significance) is likely to be caused by
repeated or prolonged exposure. As a rule the material produces, or contains a substance which produces severe lesions. Such damage may
become apparent following direct application in subchronic (90 day) toxicity studies or following sub-acute (28 day) or chronic (two-year) toxicity
tests.
