SECTION 11 Toxicological information
Information on toxicological effects
Inhaled
The material has
NOT
been classified as 'harmful by inhalation'. This is because of the lack of corroborating animal or human
evidence.
The odour of isopropanol may give some warning of exposure, but odour fatigue may occur. Inhalation of isopropanol may
produce irritation of the nose and throat with sneezing, sore throat and runny nose.
Ingestion
The material has
NOT
been classified by as 'harmful by ingestion'. This is because of the lack of corroborating animal or human
evidence.
Overexposure to non-ring alcohols causes nervous system symptoms. These include headache, muscle weakness and
inco-ordination, giddiness, confusion, delirium and coma.
Skin Contact
The material is not thought to produce adverse health effects or skin irritation following contact. Nevertheless, good hygiene
practice requires that exposure be kept to a minimum and that suitable gloves be used in an occupational setting.
Open cuts, abraded or irritated skin should not be exposed to this material
Entry into the blood-stream, through, for example, cuts, abrasions or lesions, may produce systemic injury with harmful effects.
Examine the skin prior to the use of the material and ensure that any external damage is suitably protected.
Eye
Causes serious eye irritation.
Chronic
In 1997, IARC (the International Agency for Research on Cancer) concluded that crystalline silica inhaled from occupational
sources can cause lung cancer in humans. However in making the overall evaluation, IARC noted that 'carcinogenicity was not
detected in all industrial circumstances studied. Carcinogenicity may be dependent on inherent characteristics of the crystalline
silica or on external factors affecting its biological activity or distribution of its polymorphs.' (IARC Monographs on the evaluation
of the carcinogenic risks of chemicals to humans, Silica, silicates dust and organic fibres, 1997, Vol. 68, IARC, Lyon, France.)
Skin contact with the material is more likely to cause a sensitisation reaction in some persons compared to the general
population.
Toxic: danger of serious damage to health by prolonged exposure through inhalation, in contact with skin and if swallowed.
This material can cause serious damage if one is exposed to it for long periods. It can be assumed that it contains a substance
which can produce severe defects.
Substance accumulation, in the human body, may occur and may cause some concern following repeated or long-term
occupational exposure.
Rosin (colophany) has caused allergic contact dermatitis in solderers using resin flux-cored solders, can be a sensitiser for
strings instrument players, and has caused dermatitis after use in adhesive tapes [NIOSHTEC]. It is found in many products that
commonly come in contact with the skin, including cosmetics, sunscreens, veterinary medications, adhesives, sealants, polishes,
paints and oils.
Amorphous silicas generally are less hazardous than crystalline silicas, but the former can be converted to the latter on heating
and subsequent cooling. Inhalation of dusts containing crystalline silicas may lead to silicosis, a disabling lung disease that may
take years to develop.
Long term, or repeated exposure of isopropanol may cause inco-ordination and tiredness.
Repeated inhalation exposure to isopropanol may produce sleepiness, inco-ordination and liver degeneration. Animal data show
developmental effects only at exposure levels that produce toxic effects in adult animals. Isopropanol does not cause genetic
damage.
There are inconclusive reports of human sensitisation from skin contacts with isopropanol. Chronic alcoholics are more tolerant
of the whole-body effects of isopropanol.
Animal testing showed the chronic exposure did not produce reproductive effects.
NOTE: Commercial isopropanol does not contain 'isopropyl oil', which caused an excess incidence of sinus and throat cancers in
isoproanol production workers in the past. 'Isopropyl oil' is no longer formed during production of isopropanol.
