Provide appropriate exhaust ventilation at places where dust is formed.
Hygiene measures
Avoid contact with skin, eyes and clothing. Wash hands before breaks and immediately
after handling the product.
For precautions see section 2.2.
Conditions for safe storage, including any incompatibilities

SECTION 8. EXPOSURE CONTROLS/PERSONAL PROTECTION

Appropriate engineering controls
Avoid contact with skin, eyes and clothing. Wash hands before breaks and immediately
after handling the product.
Personal protective equipment
Eye/face protection
Face shield and safety glasses Use equipment for eye protection tested and
approved under appropriate government standards such as NIOSH (US) or EN
166(EU).
Skin protection
Handle with gloves. Gloves must be inspected prior to use. Use proper glove
removal technique (without touching glove's outer surface) to avoid skin contact
with this product. Dispose of contaminated gloves after use in accordance with
applicable laws and good laboratory practices. Wash and dry hands.
Body Protection
Complete suit protecting against chemicals, The type of protective equipment must
be selected according to the concentration and amount of the dangerous substance
at the specific workplace.
Respiratory protection
Where risk assessment shows air-purifying respirators are appropriate use a full-
face particle respirator type N99 (US) or type P2 (EN 143) respirator cartridges as a backup to engineering controls. If the respirator is the sole means of protection, use
a full-face supplied air respirator. Use respirators and components tested and
approved under appropriate government standards such as NIOSH (US) or CEN
(EU).
Control of environmental exposure
Prevent further leakage or spillage if safe to do so. Do not let product enter drains.
Discharge into the environment must be avoided.

Additional Information

Inorganic tin salts are poorly absorbed into the body. When parenterally administered tin
salts are highly toxic. Tin oxide inhaled as a dust or fume leads to a benign pneumoconiosis
with no sign of interference with pulmonary function. Deposited dust appears nodular with
the particles being mostly extracelluar. No necrosis, foreign-body giant-cell reaction, or
collagen formation has been seen. Tin salts that have gained access to the blood stream
are highly toxic and produce neurologic damage and paralysis. With most common tin salts,
the toxicity profile is complicated by hydrolysis in body fluids producing unphysiologic pH
values. The reported symptoms of hyperemia, vascular changes with bleeding in the central
nervous system, liver, heart, and other organs may be due to tin itself or to the
unphysiological pH changes. Ingestion produces vomiting due to the gastric irritation from
the activity and astringency of tin compounds. Injection of inorganic tin salts produces
diarrhea, muscle paralysis, and twitching., Acute selenium poisoning produces central
nervous system effects, which include nervousness, convulsions, and drowsiness. Other
signs of intoxication can include skin eruptions, lassitude, gastrointestinal distress, teeth
that are discolored or decayed, odorous ("garlic") breath, and partial loss of hair and nails.
Chronic exposure by inhalation can produce symptoms that include pallor, coating of the
tongue, anemia, irritation of the mucosa, lumbar pain, liver and spleen damage, as well as
any of the other previously mentioned symptoms. Chronic contact with selenium
compounds may cause garlic odor of breath and sweat, dermatitis, and moderate emotional
instability.
