Hazards and Protection.
Storage
Keep container tightly closed.
Protection
Compatible chemical-resistant gloves. Chemical safety goggles. Protective clothing.
Respirators
Use respirators and components tested and approved under appropriate government standards such as NIOSH (US) or CEN (EU). 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.
Small spills/leaks
Sweep up, place in a bag and hold for waste disposal. Ventilate area and wash spill site after material pickup is complete.
Stability
Material is heat and moisture sensitive.
Incompatibilities
Acids.
Decomposition
Hydrogen fluoride, copper oxide.

Fire.
Fire fighting
Extinguish with water spray, carbon dioxide, dry chemical powder or appropriate foam. Wear self-contained breathing apparatus and protective clothing to prevent contact with skin and eyes.
Hazards
Emits toxic fumes under fire conditions.

Exposure effects
Material reacts with moisture on the skin, eyes, and mucous membranes to generate hydrogen fluoride. Hydrogen fluoride is extremely destructive and may cause deep progressive burns that induce subcutaneous tissues to become blanched and bloodless resulting in lesions of dead tissue that are slow to heal. Symptoms of fluoride overexposure may include salivation, nausea, vomiting, abdominal pain, fever, and labored breathing. Fluoride ion can reduce serum calcium levels possibly causing fatal hypocalcemia. Prolonged exposure to fluoride dusts, vapors, or mists results in perforation of the nasal septum. Chronic effects include excessive calcification of the bones, ligaments, and tendons. Material is extremely destructive to tissue of the mucous membranes and upper respiratory tract, eyes, and skin. Inhalation may result in spasm, inflammation and edema of the larynxand bronchi, chemical pneumonitis, and pulmonary edema. Symptoms of exposure may include burning sensation, coughing, wheezing, laryngitis, shortness of breath, headache, nausea, and vomiting. Chronic copper poisoning is typified by hepatic cirrhosis, brain damage and demyelination, kidney defects, and copper deposition in the cornea as exemplified by humans with Wilson's disease. It has also been reported that copper poisoning has lead to hemolytic anemia and accelerates arteriosclerosis. Eye contact with copper dust may cause irritation with redness and pain. Copper particles in the eye may cause discoloration of the ocular tissue, degeneration and/or detachment of the retina. Contact of copper dust with skin may cause keratinization. Inhalation of copper dust may cause ulceration and perforation of the nasal system. Copper fume may cause metal fume fever. Symptoms may include sweet, metallic taste in mouth; coughing; fever; muscle aches; nausea; and headache.
   Ingestion
Harmful if swallowed.
   Inhalation
Material is extremely destructive to the tissue of the mucous membranes and upper respiratory tract. Harmful if inhaled.
   Skin
Causes burns. Harmful if absorbed through skin.
   Eyes
Causes burns.

First aid
 
   Ingestion
If swallowed, wash out mouth with water provided person is conscious. Call a physician.
   Inhalation
If inhaled, remove to fresh air. If not breathing give artificial respiration. If breathing is difficult, give oxygen.
   Skin
In case of contact, immediately wash skin with soap and copious amounts of water. Remove contaminated clothing and shoes. Call a physician.
   Eyes
In case of contact with eyes, flush with copious amounts of water for at least 15 minutes. Assure adequate flushing by separating the eyelids with fingers. Call a physician.
