Reacts as a base to neutralize acids Reacts within a few seconds with solutions of sodium hypochlorite.
Fire Extinguishing Agents: Water, foam
Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes.
Contact with metals may evolve flammable hydrogen gas.
Toxic oxides of nitrogen may form in fire.
Increased deep tendon reflexes, drowsiness, stupor, seizures and coma may be noted.
Persistent vomiting, hematemesis and hemorrhagic gastritis due to the corrosive action of oxalic acid on the mucous membranes may occur immediately following ingestion.
Cough, sore throat. Irritates eyes, skin and respiratory tract. May cause effects on the central nervous system and kidneys, resulting in impaired functions. <BR>Chronic effects - May have effects on the kidneys.
Dermal exposure may result in corrosive action on the skin. Skin lesions begin with epithelial cracking and the formation of slow-healing ulcers.
Redness, pain, severe deep burns.
Seek medical assistance.
