Section 2 – Hazard Identification
Emergency Overview
Flammable liquid. Primarily toxic by ingestion. Contact with skin may cause dryness and cracking. May
cause irritation to the eyes and the respiratory system. Wash areas of contact with water.
Appearance: Brown liquid
Odor: Alcohol-like
Target Organs: Eyes, skin, respiratory system, central nervous system, liver, pancreas, cardiovascular
system.
Potential Health Effects/ Routes of Exposure:
Eyes: May cause irritation with stinging and burning with possible damage to the conjunctiva and cornea.
Skin: Results in drying and cracking which can lead to secondary infections and dermatitis.
Ingestion: Symptoms can include sleep disorders, hallucinations, distorted perceptions, ataxia, motor
function changes, convulsions and tremors, coma, headaches, pulmonary changes, and alteration of
gastric secretions.
Inhalation: May cause irritation of the nose and mucosa of the respiratory tract. Exposure to high
concentrations can cause suppression of the central nervous system with symptoms of sleepiness and
lack of concentration.
Chronic Effect / Carcinogenicity Chronic ingestion may cause thyroid disease. Carcinogenicity – None
(IARC, NTP, OSHA)

Ingestion: Immediately dilute with water and induce vomiting. Contact a physician.
Inhalation: Remove to fresh air. Give artificial respiration if necessary. If breathing is difficult, give
oxygen.
Notes to Physician Treat symptomatically and supportively.
Section 5 – Fire Fighting Measures
Flash Point: 24-27C
Autoignition Temperature No information available
Explosion Limits Upper NA
Lower NA
Extinguishing Media: Use dry chemical, water spray, alcohol foam, or carbon dioxide for extinguishing
the surrounding fire. Water spray can be used to dilute spills to non-flammable concentrations.
Unsuitable Extinguishing Media: No information available
Fire & Explosion Hazards Vapors can flow along surfaces to distant ignition source and flashback. Use
water spray to cool fire exposed containers, blanket fire, and to flush non-ignited spills or vapors away
from the fire. Explosion hazard when exposed to heat, flame or oxidizers.
Fire Fighting Instructions / Equipment: Poisonous gases are produced in fire. Continue to cool
containers with water after fire is extinguished. For larger fires, use unmanned hose apparatus, if
possible. Consider down wind conditions. Do not let runoff from fire-fighting measures enter sewers or
water ways. As in any fire, wear protective clothing and NIOSH-approved self-containing breathing
apparatus.

Section 6 – Accidental Release Measures
Personal Precautions Use personal protective equipment. Ensure adequate ventilation. Avoid contact
with skin, eyes and clothing.
Environmental Precautions Should not be released into the environment.
Methods for Containment and Clean Up Remove all sources of ignition. Contain spill. Do not flush to
sewer. Absorb and containerize in a suitable container for proper disposal. Ventilate area of spill. Use
non-sparking tools and equipment. Always obey local regulations.
Section 7 – Handling and Storage
Handling: Wash hands thoroughly after handling. Avoid contact with skin, eyes and clothing. Keep away
from all sources of ignition. Empty containers may be hazardous since they retain product residue.
Storage: Keep containers tightly closed in a cool, dry environment. Protect from freezing and physical
damage. Store in a flammable storage area away from all sources of ignition.
