Hazards and Protection.
Storage
Safety cans should be used for storing flammable solvents.
Handling
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.
Protection
Gloves should be used and skin contact avoided at all times.
Respirators
Use NIOSH/MSHA approved respirator appropriate for exposure of concern.
Small spills/leaks
If you should spill this chemical, FIRST REMOVE ALL SOURCES OF IGNITION, then use absorbent paper to pick up all liquid spill material. Your contaminated clothing and absorbent paper should be sealed in a vapor-tight plastic bag for eventual disposal. Solvent wash all contaminated surfaces with acetone followed by washing 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.
Stability
Volatility of uncured epoxy resins is not great. The substance can presumably form explosive peroxides.
Incompatibilities
React with acids, bases, and oxidizing and reducing agents.
Decomposition
When heated to decomposition, it emits acrid smoke and irritating fumes.

Exposure effects
Epichlorohydrin ingestion has resulted in cyanosis, muscular relaxation or paralysis, tremor, seizures, and respiratory arrest in animal studies.
   Ingestion
Ingestion of polyamines may result in burns to the oral pharynx and esophagus. Dysphagia and drooling may be noted.
   Inhalation
Fumes from cured epoxy resins may result in coughing, and bronchospasm persisting for several days.
   Skin
Allergic contact dermatitis occurs in a significant number of occupational exposures. Exposures may result in severe burns to the skin. Eczema, urticaria and photodermatitis have been reported following dermal exposures.
   Eyes
Fumes from cured epoxy resins may result in periorbital edema, facial pruritus and inflammation of the eye.

First aid
 
   Ingestion
DO NOT INDUCE VOMITING. 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. Be prepared to transport the victim to a hospital if advised by a physician.
   Inhalation
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.
   Skin
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.
   Eyes
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.
