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.
