Hazards and Protection.
Storage
Do not store near any material intended for use or consumption by humans or animals. KEEP OUT OF REACH OF CHILDREN.
Protection
Chemical goggles should be worn when handling. Wear clean long sleeved shirt and long pants, shoes and socks and waterproof gloves,. Launder contaminated clothing separately.
Respirators
Wear appropriate NIOSH/MSA dust mask if exposure limit would be exceeded
Small spills/leaks
Sweep up or vacuum. Create a minimum of dust in clean up operations. Observe the personal protective equipment recommendations during clean up.
Stability
Stable under normal storage conditions.
Incompatibilities
Magnesium produces hydrogen. Hydroxylammine may ignite when mixed with anhydrous copper sulfate. Sodium hypobromite solutions are decomposed by catalytic action of cupric ions.
Decomposition
Oxides of copper and sulfur may occur with thermal decomposition.

Fire.
Fire fighting
Dry chemical, CO2, water fog, foam. Prevent human exposure to fire, smoke, fumes or products of decomposition. Wear self contained breathing apparatus and full cover protective clothing. Water spray to cool product is preferred to directed high pressure streams.

Exposure limit(s)
OSHA PEL 1 mg/m3 as Cu.
Exposure effects
Repeated or prolonged inhalation of dust, mist or fumes of copper may cause irritation of the upper respiratory tract and occasionally ulceration and perforation of the nasal septum. Depending on concentration and duration of contact, repeated or exposure to eyes may result in symptoms as in acute exposure Repeated or prolonged exposure may cause dermatitis. Rarely, sensitization to copper may occur. Repeated ingestion of copper salts may result in anemia, liver and kidney damage.
   Ingestion
May result in irritation of the gastrointestinal tract, nausea, vomiting, salivation, gastric pain, hemorrhagic gastritis, diarrhea, capillary damage, liver and kidney damage, and central nervous system stimulation, followed by depression. Jaundice, pain in the liver, and hemolytic anemia have been reported following acute human poisonings.
   Inhalation
Strong irritant to nose and throat. Inhalation of dust and spray mist my cause irritation of upper respiratory tract. Excessive exposure may cause cough, mucous production, shortness of breath reflecting metal fume fever.
   Skin
Slight skin irritant. Excessive exposure, especially if prolonged, may produce skin irritation. Repeated exposure may cause allergic contact dermatitis.
   Eyes
Severe eye irritant. May be corrosive to eyes. Causes substantial but temporary eye injury.

First aid
