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 particlerespirator 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).

Additional Information
RTECS: Not available
Acute inhalation exposure to cadmium fumes may cause "metal fume fever" with flu-like symptoms ofweakness, fever, headache, chills, nausea, vomiting, dizziness, sweating, muscular pain, cough and
difficulty breathing. Acute
pulmonary edema may develop within 24 hours and reaches a maximum by three days.The first
chronic effect of exposure to cadmium is generally kidney damage, manifested by excretion of
excessive protein in the urine, followed by anemia, teeth discoloration and loss of smell. Cadmium
also is believed to cause pulmonary emphysema and bone disease., To the best of our knowledge,
the chemical, physical, and toxicological properties have not been thoroughly investigated.
