Irritant, Combustible Liquid
FIRST-AID MEASURES EYES: Flush with water for 15 minutes. Seek medical advice if irritation persists.
SKIN: Flush with water, then wash thoroughly with soap and water. Remove contaminated clothing and
wash before reuse. Seek medical attention if irritation persists.
INHALATION: Remove the victim from exposure and move to fresh air. If breathing is difficult, give
oxygen. If not breathing, give artificial respiration. Keep victim quiet and warm. Seek immediate
medical attention.
INGESTION: Drink water and seek immediate medical attention. Avoid alcoholic beverages. Never give
anything by mouth to an unconscious person.
FIRE-FIGHTING INFORMATION Use media suitable to extinguish the supporting or surrounding fire. Wear NIOSH (or equivalent) approved self
contained breathing apparatus. For small fires only: use carbon dioxide, dry powder or foam. Vapors may be
heavier than air, spread along the ground and collect in low or confined areas. Containers may explode when
heated. Combustible liquid. Emits toxic fumes under fire conditions.
Flash Point = 69掳C (157掳F).
ACCIDENTAL RELEASE MEASURES Wear appropriate personal protective equipment and clothing including lab coat, safety goggles, gloves and
NIOSH-approved respirator. Eliminate all sources of ignition. Cover with dry-lime, sand or soda ash. Using non-
sparking tools, collect in a manner that does not create dust and place in a suitable waste container. Avoid
contact of material with skin or eyes. Use adequate ventilation.
HANDLING AND STORAGE CAUTION: Use caution when opening container. Contents may be under pressure. Wear appropriate personal
protective equipment and clothing including lab coat, safety goggles, gloves and NIOSH-approved respirator.
Avoid all sources of ignition. Ground all equipment. Avoid contact of material with skin or eyes. Use adequate
ventilation. Moisture sensitive. Store at !20掳C away from incompatible material. Keep away from heat, sparks
and flame.
PERSONAL PROTECTION Wear appropriate personal protective equipment and clothing including lab coat, safety goggles, gloves and
NIOSH-approved respirator. A qualified industrial hygienist should evaluate the need for respiratory protection.
Use respiratory protection approved by NIOSH (or equivalent) and appropriate to the hazard. Avoid contact of
material with skin or eyes. Mechanical ventilation or local exhaust as needed to control exposure to dust,
vapors or mists. Access to a safety shower and eye-wash. Wash thoroughly after handling.

STABILITY AND REACTIVITY DEPC hydrolyzes in the presence of moisture to form ethanol and carbon dioxide. Caution. Contents may be
under pressure. Remove the cap with caution. Conditions to avoid: heat, sparks, flames and other sources of
ignition. Incompatible with moisture, strong oxidizing agents, strong acids, strong bases, ammonia and strong
reducing agents. Hazardous decomposition products include carbon oxides. Hazardous polymerization will not
occur.
TOXICOLOGICAL INFORMATION EFFECTS OF OVEREXPOSURE:
EYES: Contact may cause irritation. Prolonged or repeated contact may result in conjunctivitis.
SKIN: May be harmful if absorbed through the skin. Contact may cause irritation. Prolonged or repeated
contact may result in dermatitis.
INHALATION: May be harmful if inhaled. May cause irritation. Vapor or mist may be irritating to the eyes,
mucous membranes and upper respiratory tract. Aspiration may lead to pulmonary edema. Inhalation at
high concentrations may cause CNS depression and asphyxiation.
INGESTION: Harmful if ingested. This product is moderately toxic by ingestion. May cause gastrointestinal
irritation with nausea, vomiting and diarrhea.
