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

N100 (US) or type P3 (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

RTECS: WE0350000

anemia, Vomiting, Diarrhoea, Cough, Difficulty in breathing, 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., Dermatitis, garlic-like breath odor, pallor, nervousness,
