Material Safety Data Sheet
11. Toxicological Information
11.1. Information on toxicological effects
a) Inhaled
The material is not thought to produce either adverse health effects or irritation of the respiratory tract following inhalation (as
classified by EC Directives using animal models). Nevertheless, adverse systemic effects have been produced following
exposure of animals by at least one other route and good hygiene practice requires that exposure be kept to a minimum and
that suitable control measures be used in an occupational setting.
Metals which form part of massive metals and their alloys, are "locked" into a metal lattice; as a result they are not readily
bioavailable following inhalation. Mechanical processing of massive metals (e.g. cutting, grinding) may cause irritation of the
upper respiratory tract. Additional health effects from elevated temperature processing (e.g., welding) can cause metal fume
fever (nausea, fever, chills, shortness of breath and malaise), reduced ability of the blood to carry oxygen (methaemoglobin)
and the accumulation of fluid in the lungs (pulmonary oedema).
The inhalation of small particles of metal oxide results in sudden thirst, a sweet, metallic foul taste, throat irritation, cough, dry
mucous membranes, tiredness and general unwellness. Headache, nausea and vomiting, fever or chills, restlessness,
sweating, diarrhoea, excessive urination and prostration may also occur.
b) Ingestion
Accidental ingestion of the material may be harmful; animal experiments indicate that ingestion of less than 150 gram may be
fatal or may produce serious damage to the health of the individual.
Metals which form part of massive metals and their alloys, are "locked" into a metal lattice; as a result they are not readily
bioavailable following ingestion. Secondary processes (e.g. change in pH or intervention by gastrointestinal microorganisms)
may allow certain substances to be released in low concentrations.
Tin salts are not very toxic. However, at high concentration, nausea, vomiting and diarrhoea can occur.
c) Skin Contact
Skin contact is not thought to produce harmful health effects (as classified under EC Directives using animal models).
Systemic harm, however, has been identified following exposure of animals by at least one other route and the material may
still produce health damage following entry through wounds, lesions or abrasions.
Particles and foreign bodies produced by high speed processes may be penetrate the skin. Even after the wound heals
persons with retained foreign bodies may experiencing sharp pain with movement or pressure over the site. Discolouration or a
visible mass under the epidermis may be obvious. Numbness or tingling ("pins and needles"), with decreased sensation, may
be the result of a foreign body pressing against nerves.
Open cuts, abraded or irritated skin should not be exposed to this material
d) Eye
This material can cause eye irritation and damage in some persons.
Contact with the eye, by metal dusts, may produce mechanical abrasion or scratches on the cornea - these injuries usually are
minor. However foreign body penetration of the eyeball may produce infection or result in permanent visual damage.
High-speed machines (such as drills and saws) can produce white-hot particles of metal that resemble sparks. Any of these
white-hot particles can enter the unprotected eye and become embedded deep within it.
Corneal abrasions caused by particles and foreign bodies usually cause pain, tearing, and a feeling that there is something in
the eye. They may also cause redness (due to inflamed blood vessels on the surface of the eye) or, occasionally, swelling of
the eye and eyelid. Vision may become blurred. Light may be a source of irritation or may cause the muscle that constricts the
pupil to undergo a painful spasm.
