Section 3 - Hazards Identification
Emergency Overview
Appearance: Clear, yellow solution
Warning! Flammable liquid and vapor. May cause eye, skin, and respiratory tract irritation. May
be harmful if swallowed. May cause central nervous system depression. May cause dermatitis.
Harmful to aquatic organisms; may cause long-term adverse effects in the aquatic environment.
Target Organs: Central nervous system, liver.
Potential Health Effects
Eye:
May cause moderate eye irritation. May result in corneal injury.
Skin:
May cause moderate skin irritation. Prolonged and/or repeated contact may cause defatting of the
skin and dermatitis.
Ingestion:
May cause gastrointestinal irritation with nausea, vomiting and diarrhea. May cause central nervous
system depression, characterized by excitement, followed by headache, dizziness, drowsiness, and

nausea. Advanced stages may cause collapse, unconsciousness, coma and possible death due to
respiratory failure.
Inhalation:
Inhalation of vapor may cause respiratory tract irritation. May cause effects similar to those
described for ingestion.
Chronic:
Prolonged or repeated skin contact may cause defatting and dermatitis. Chronic exposure may cause
liver damage.
Section 4 - First Aid Measures
Eyes:
Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower
eyelids. Get medical aid.
Skin:
Get medical aid. Flush skin with plenty of water for at least 15 minutes while removing
contaminated clothing and shoes. Wash clothing before reuse.
Ingestion:
Do not induce vomiting. If victim is conscious and alert, give 2-4 cupfuls of milk or water. Never
give anything by mouth to an unconscious person. Get medical aid.
Inhalation:
Remove from exposure and move to fresh air immediately. If not breathing, give artificial
respiration. If breathing is difficult, give oxygen. Get medical aid.
Notes to Physician:
Treat symptomatically and supportively.
Section 5 - Fire Fighting Measures
General Information:
As in any fire, wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH
(approved or equivalent), and full protective gear. Combustion generates toxic fumes. During a fire,
irritating and highly toxic gases may be generated by thermal decomposition or combustion.
Flammable liquid. Can release vapors that form explosive mixtures at temperatures above the
flashpoint. Vapors may be heavier than air. They can spread along the ground and collect in low or
confined areas.
Extinguishing Media:
Use water spray to cool fire-exposed containers. Use dry chemical, carbon dioxide, or alcohol-
resistant foam. Do NOT use straight streams of water.
Autoignition Temperature:
405 癈 (761 癋)
Flash Point:
15 癈 (59 癋)
NFPA Rating:
(estimated) Health: 1, Flammability: 3, Instability: 1
Explosion Limits:
Lower: 2.2 % Upper: 13.7 %

Section 6 - Accidental Release Measures
General Information:
Use proper personal protective equipment as indicated in Section 8.
Spills/Leaks:
Absorb spill with inert material (e.g. vermiculite, sand or earth), and then place in suitable container.
Avoid runoff into storm sewers and ditches that lead to waterways. Clean up spills immediately,
observing precautions in the Protective Equipment section. Remove all sources of ignition. Provide
ventilation.
Section 7 - Handling and Storage
Handling:
Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Use with
adequate ventilation. Use spark-proof tools and explosion proof equipment. Empty containers retain
product residue, (liquid and/or vapor), and can be dangerous. Do not get on skin or in eyes. Do not
ingest or inhale. Do not pressurize, cut, weld, braze, solder, drill, grind, or expose empty containers
to heat, sparks or open flames.
Storage:
Keep away from heat, sparks, and flame. Do not store near combustible materials. Store in a cool,
dry place. Store in a tightly closed container. Keep from contact with oxidizing materials.
Section 8 - Exposure Controls, Personal Protection
Engineering Controls:
Facilities storing or utilizing this material should be equipped with an eyewash facility and a safety
shower. Use adequate ventilation to keep airborne concentrations below the permissible exposure
limits.
