Reactivity Data
When heated, this product can decompose to release toxic arsenic and lead fumes.
Toxicological Properties3
This cake is a complex mixture. The toxicological properties are expected to be related to the
composition of the mixture. The toxicological properties of the major ingredients are listed below.
Inco Lead carbonate The International Agency For Research On Cancer (IARC) concluded that
there is inadequate evidence that lead and lead compounds are carcinogenic
to humans. However, there is sufficient evidence that inorganic lead
compounds are carcinogenic to animals.
Material Anemia caused by inorganic lead inhibiting the production of blood
hemoglobin is an early sign of lead poisoning.
Of the various lead compounds, the carbonate, the monoxide, and the
Safety sulphate are considered more toxic than metallic lead or other lead
compounds.
IARC concluded that there is sufficient evidence that arsenic and arsenic
Data compounds, as a group but not necessarily as individual chemicals, are
carcinogenic to humans. The association between environmental exposure to
arsenic in contaminated drinking water, and skin cancer has been observed
and confirmed. Two cases of bladder cancer were also confirmed. U.S.
Sheet Smelter workers exposed to inorganic arsenic have been shown to have
significant and consistent increases in lung cancer. Arsenic compounds can
be absorbed by inhalation or ingestion.
Acute arsenic poisonings can be fatal. Symptoms of fatal poisonings are
abdominal pain and vomiting, usually within an hour or ingestion. In some
cases, dermatitis and peripheral neuritis follow recovery from acute symptoms.
Acute dermatitis starts with erythema associated with burning and itching,
giving the skin a mottled appearance. If the dermatitis is on the face, swelling
may occur followed by eruptions of the skin.
Chronic skin lesions caused by exposure to arsenic compounds are
characterized by cracking, thickening, and drying of the skin, warts and
excessive sweating. Dermatitis of the face and eyelids can be accompanied
by conjunctivitis with redness, swelling and pain.
Arsenic-bearing dust in contact with moist skin, eyes or nasal passages can
form arsenious acid causing irritation and in some cases, corroding of the
septal mucosa. Iron III arsenate can emit toxic fumes of arsenic when heated
to decomposition.
Ferrous hydroxide
(Fe(OH)2 A search of the literature revealed no pertinent toxicological data for
ferrous hydroxide.
Silica, amorphous IARC has concluded there is inadequate evidence that amorphous silica
was carcinogenic to humans and animals. In some animal studies, amorphous
silica has been shown to be fibrogenic resulting in reduced lung function.
In human studies, amorphous silica (diatomaceous earth, precipitated and
gel) seems to have little adverse effect on lungs when exposures are

reasonably controlled. There is not enough industrial experience to indicate the
degree of hazard for amorphous silica (fused).
Bismuth oxychloride Not available.
Preventative Measures
As supplied, the product is visibly wet and ventilation is normally not required. If dried, or allowed
to dry in a user operation, ventilation is required to keep exposure to airborne contaminants below
Inco the exposure limits. If ventilation alone cannot so control exposure, use NIOSH-approved
respirators selected according to the selection, care and use of respirators CSA Z94.4-M1993.
Do not store near acids.
Material Avoid breathing dust.
Avoid skin and eye contact wash thoroughly after handling. Launder clothing and gloves as
Safety needed. Keep container closed.
First Aid Measures
For respiratory tract
Data irritation Remove to fresh air. If symptoms persist,
get medical attention for skin irritation, flush thoroughly with plenty of water.
For rashes Seek medical attention
Sheet For eye irritation Immediately flush with water for 15 minutes. Seek medical attention. Hold
eyelids open while flushing with water.
If ingested Seek medical attention
