Hazards and Protection.
Commercial aqueous solution a mixture of several nonvolatile hydrated forms in equilibrium.
All chemicals should be considered hazardous. Avoid direct physical contact. Use appropriate, approved safety equipment. Untrained individuals should not handle this chemical or its container. Handling should occur in a chemical fume hood.
Wear protective clothing and self-contained breathing apparatus.
Wear positive pressure self-contained breathing apparatus (SCBA).
If you should spill this chemical, use absorbent paper to pick up all liquid spill material. Seal the absorbent paper, as well as any of your clothing which may be contaminated, in a vapor-tight plastic bag for eventual disposal. Wash any surfaces you may have contaminated with a soap and water solution. Do not reenter the contaminated area until the Safety Officer (or other responsible person) has verified that the area has been properly cleaned.
Polymerizes violently when contacted with water.
React vigorously with strong oxidizing agents such as nitric acid Reacts with itself in the presence of base to give glyconates.
Fires involving this material can be controlled with a dry chemical, carbon dioxide or Halon extinguisher.
Slightly flammable. Very flammable at elevated temperatures.
Heat may cause polymerization to a combustible, viscous material.
Fire may produce irritating, corrosive and/or toxic gases.
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.
TOXIC; inhalation, ingestion, or skin contact with material may cause severe injury or death. Effects of contact or inhalation may be delayed.
Dermal exposure may result in corrosive action on the skin. Skin lesions begin with epithelial cracking and the formation of slow-healing ulcers.
DO NOT INDUCE VOMITING. Volatile chemicals have a high risk of being aspirated into the victim's lungs during vomiting which increases the medical problems. If the victim is conscious and not convulsing, give 1 or 2 glasses of water to dilute the chemical and IMMEDIATELY call a hospital or poison control center. IMMEDIATELY transport the victim to a hospital.
IMMEDIATELY leave the contaminated area; take deep breaths of fresh air. If symptoms (such as wheezing, coughing, shortness of breath, or burning in the mouth, throat, or chest) develop, call a physician and be prepared to transport the victim to a hospital. Provide proper respiratory protection to rescuers entering an unknown atmosphere. Whenever possible, Self-Contained Breathing Apparatus (SCBA) should be used.
IMMEDIATELY flood affected skin with water while removing and isolating all contaminated clothing. Gently wash all affected skin areas thoroughly with soap and water. If symptoms such as redness or irritation develop, IMMEDIATELY call a physician and be prepared to transport the victim to a hospital for treatment.
First check the victim for contact lenses and remove if present. Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center. Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician. IMMEDIATELY transport the victim after flushing eyes to a hospital even if no symptoms (such as redness or irritation) develop.
