8.2 Exposure controls
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.

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., Gastrointestinal
disturbance, Dizziness, Nausea, Headache, Vomiting, Diarrhoea, Abdominal pain, May cause argyria (a slate-gray or
bluish discoloration of the skin and deep tissues due to the deposit of insoluble albuminate of silver)., To the best of our
knowledge, the chemical, physical, and toxicological properties have not been thoroughly investigated.
