ACGIH TLV TWA: 1.0 mg/m3 (as copper dust/mist)

1.0 mg/m3 (as copper dust/mist)

Emergency overview: Odorless blue crystals. Can cause irreversible eye damage and severe skin irritation. Harmful if swallowed or absorbed through the skin. Avoid breathing dust or mist. Avoid contact with the skin, eyes or clothes. May cause skin sensitization in certain individuals.
Swallowing: Toxic orally in accordance with FHSLA regulations. Acute oral LD50 (male rats) = 472 mg/Kg. Can cause irritation to the digestive tract and abdominal pain.
Skin : Slight skin irritant. Excessive exposure may cause skin irritation. Repeated exposure may cause allergic dermititis. May cause irritation or burns on wet skin.
Eyes: Can cause severe eye irritation and may result in irreversible eye damage.
Inhalation: Inhalation of dust may cause irritation to the mucous membranes and upper respiratory tract
Carcinogenicity: None as per NTP, OSHA, and IARC.

Ingestion: Give large amounts of milk, egg white, gelatin solution, or if they are not available, large quantities of water. Do not induce vomiting or give anything to an unconscious person. Avoid alcohol. Call Poison Control Center or a physician.
Skin: Wash thoroughly with soap and water. Remove and wash contaminated clothing before reuse.
Eyes: Immediately flush eyes with plenty of water for 15 minutes. Hold eyelids apart during irrigation. Call a physician.
Inhalation: Remove person to fresh air. If not breathing, administer artificial respiration. Get medical attention.
Carcinogenicity: None.

Flash Point: Not applicable.
Flammable Limits: Not flammable. If heated above 400o C it can decompose to emit toxic fumes of oxide and sulfur. Auto Ignition Temperature: Not determined.
Extinguishing Media: Copper Sulfate does not burn nor will it support combustion. If stored with other combustible products use water, CO2 or dry chemical.
Special Fire Fighting Instructions: If dry heated above 600o C, SO2 is evolved. If water is used it will solubalize the Copper Sulfate and care should be taken to keep such water out of streams or other water bodies.
Fire Fighting Equipment: Wear self-contained breathing apparatus.
Fire and Explosion Hazards: None.

Use clean-up measures that avoid dust generation. Wear NIOSH or MSHA approved respirator if dust will be generated. Cover spill with absorbent material such as seeping compound or lime. Sweep up and put into an appropriate container for proper disposal in an approved method. Prevent accidental entry of solution into streams or other bodies of water. Shovel spills into plastic bags and seal with tape.

Signal Word: DANGER
Handling Information: Avoid breathing dust or mist. Sweep up crystals. Eye wash stations should be available in work areas. Users should wash hands before eating, drinking, smoking or using the toilet. Remove PPE immediately after handling this product. Wash outside of gloves before removing. Wash and change into clean clothing as soon as possible. Storage Information: Store in closed containers in a cool, dry, well ventilated area away from heat sources and reducing agents. Store in original containers. Keep away from galvanized pipe, aluminum and nylon. Place damaged containers in plastic bags.

Ventilation: TWA = 1 mg/l. for Copper Sulfate. When TWA exceeds this limit in the workplace, provide appropriate ventilation.
Respiratory Protection: Wear an approved respirator for dusts or mists: MSHA/NIOSH approved number prefix TC-21C, or a NIOSH approved respirator with any R, P or HE filter. Alternatively, provide respiratory protection equipment in accordance with Paragraph 1910.134 of Title 29 of the Code of Federal Regulations.
Eye Protection: Use safety glasses with side shields or goggles.
Skin Protection: Applicators and other handlers should wear long sleeved shirts and long pants, waterproof gloves, shoes plus socks and protective eyewear. Discard clothing and other absorbent materials that have been drenched or heavily contaminated with product's concentrate. Do not reuse them. Keep and wash PPE separately from other laundry.

Physical State: Blue crystals or powder

Molecular Weight: 249.68
Appearance: Transparent blue crystals
Odor: Odorless

Stability: Stable
Conditions to Avoid: Product is highly soluble, but does not react with water.
Incompatibility: Solutions are mildly corrosive to steel. Store solutions in plastic or rubber or 304, 347 or 316 stainless steel. Iron and moisture should be avoided. Store in a dry area. Incompatible with aluminum powder, acetylene gas, hydroxylamine, magnesium and moisture. Contact with magnesium can generate dangerous levels of hydrogen gas. With exposure to air it will oxidize and turn whitish. Hazardous Decomposition Products: None at normal production temperatures and pressures. If dry heated above 600oC toxic sulfur may evolve.
Polymerization: Will not occur.

Inhalation: LC50 > 2.95 mg/L (rat) Inhalation of dust can result in irritation of nasal mucous membranes and sometimes of the pharynx, on occasion ulceration with perforation of the nasal septum.
Skin: LD50 > 8.0 g/kg (rabbit)
Ingestion: LD50 > 472.5 mg/kg (rat)
Primary Eye Irritation: Corrosive, irreversible eye damage.
Primary Skin Irritation: No skin irritation.
Note to Physician: Probable mucosal damage may contraindicate the use of gastric lavage. Measures against circulatory shock, respiratory depression and convulsions may be needed. Wilson's disease can be aggravated by excessive exposure. Symptoms include nausea, vomiting, epigastria pain, diarrhea, dizziness, jaundice, and general debility.
