3. HAZARDS IDENTIFICATION
Emergency Overview
Appearance, form, odor: Colorless mobile liquid with solvent odor.
DANGER! EXTREMELY FLAMMABLE. Keep away from heat, sparks, open flame. EYE, SKIN, AND RESPIRATORY
SYSTEM IRRITANT. Avoid skin and eye contact. Wash thoroughly after handling. Avoid breathing vapor. Use with
adequate ventilation. Keep container closed when not in use.
Contains: Ketones (78-93-3 and 67-64-1) and Propylene Oxide (75-56-9)
"This product contains a chemical known to the State of California to cause cancer". "This product contains a chemical
known to the State of California to cause birth defects or other reproductive harm."
FIRST AID: Eyes-flush with water for 15 minutes. Get immediate medical attention. Skin-remove contaminated
clothing and excess contaminant, flush skin with soap and water. Inhalation-remove to fresh air. Ingestion-get
immediate medical attention.
See Material Safety Data Sheet for more complete information.
KEEP OUT OF REACH OF CHILDREN!
Potential health effects
Skin contact Skin absorption Eye contact Inhalation Ingestion
Primary routes of exposure:
Symptoms of acute overexposure:
Skin: Moderately irritating. Prolonged or repeated liquid contact can result in defatting/ drying of skin resulting in irritation
and dermatitis.
Eyes: Mildly irritating. High vapor concentrations may also be irritating.
Inhalation:
Vapors may irritate nose, throat, respiratory tract. High vapor concentration may cause CNS depression (giddiness,
headache, dizziness, nausea; in extreme cases- unconsciousness and death).
Ingestion:
Moderately toxic. May produce CNS depression (headache, dizziness, lethargy, weakness, personality change, poor
appetite and nausea).
Effects of chronic overexposure:
Dermatitis may result from prolonged or repeated skin overexposures. Repeated excessive overexposures to
solvents has caused liver, blood and kidney damage in laboratory animals. Propylene Oxide is an NTP and IARC
carcinogen.
Carcinogenicity -- OSHA regulated: No ACGIH: No National Toxicology Program: Yes
International Agency for Research on Cancer:Yes
Cancer-suspect constituent(s) : Propylene oxide
Medical conditions which may be aggravated by exposure:
Preexisting eye, skin, and respiratory disorders.
Other effects:
MEK has demonstrated to potentiate (shorten the time of onset) of peripheral neuropathy caused by either n-hexane
or methyl n-butyl ketone. MEK by itself has not been demonstrated to cause peripheral neuropathy.
MEK can potentiate the neurotoxicity of hydrocarbon compounds (n-hexane, methyl-n-butylketone, and 2,5-
hexanedione) and the liver and kidney toxicity of haloalkane solvents.

4. FIRST AID MEASURES
First aid for eyes:
Flush eye with clean water for at least 15 minutes while gently holding eyelids open. Get immediate medical
attention.
First aid for skin:
Immediately remove contaminated clothing and excess contaminant. Flush skin with water. Wash thoroughly with
soap and warm water. Consult a physician if irritation develops.
First aid for inhalation:
Remove patient to fresh air. Administer oxygen if breathing is difficult. Get medical attention if symptoms persist.
First aid for ingestion:
Give two glasses of water if patient is NOT unconscious or drowsy; induce vomiting by giving 2 tablespoons syrup of
IPECAC. Keep victims head below hips while vomiting. Get medical attention.
5. FIRE FIGHTING MEASURES
General fire and explosion characteristics:
Flammable liquid class IB.
Extinguishing media:
Carbon dioxide Dry chemical Foam Alcohol foam
Water
Flash Point (癋): -35 Method: TOC
Explosive limits in air (percent) -- Lower: 0.5 Upper: 38.5
Special firefighting procedures:
Clear area of unprotected personnel. Do not enter confined fire space without full bunker gear (helmet with face
shield, bunker coats, gloves and rubber boots) and positive pressure NIOSH approved self-contained breathing
apparatus. Cool fire exposed containers with water spray.
Unusual fire and explosion hazards:
Danger! This product is extremely flammable. May cause flash fire. Containers exposed to intense heat from fires
could rupture from vapor pressure buildup.
Hazardous products of combustion:
Thermal decomposition yields oxides of carbon and nitrogen; toxic smoke, and other unknown organic compounds.
6. ACCIDENTAL RELEASE MEASURES
Spill control:
Avoid personal contact. Eliminate ignition sources. Ventilate area.
Containment:
Dike, contain and absorb with clay, sand or other suitable material.
Cleanup:
Wear appropriate respirator and protective clothing. For large spills, pump to storage/salvage vessels. Soak up
residue with an absorbent such as clay, sand, or other suitable material and dispose of properly. Flush area with
water to remove trace residue. Small spills- take up with an absorbent material and place in appropriate containers
for disposal.
Special procedures:
Prevent spill from entering drainage/sewer systems, waterways, and surface waters. Use bonding/ grounding lines
and non-sparking tools.

7. HANDLING AND STORAGE
Handling precautions:
Keep away from heat, sparks, and flames. Surfaces that are sufficiently hot may ignite even liquid product in the
absence of sparks or flame. Extinguish pilot lights, cigarettes and other sources of ignition prior to use and until all
vapors are gone. Vapors may accumulate and travel to ignition sources distant from the handling site - flash fire can
result. Empty containers can contain explosive vapors. Do NOT cut, drill, grind, weld, or perform similar operations
on or near containers. Do NOT pressurize drum containers to empty them. Use grounding/ bonding lines to prevent
accumulation of static electricity. Wash with soap and water before eating, drinking, smoking, applying cosmetics, or
using toilet facilities. Launder contaminated clothing before reuse. Air-dry contaminated clothing in a well ventilated
area before laundering. ---Warning: This product contains a chemical known to the State of California to cause
cancer.
Storage:
Keep away from heat, sparks, and flames. Keep containers closed when not in use. Do not store above 100 deg F.
8. EXPOSURE CONTROLS/PERSONAL PROTECTION
Engineering controls
Ventilation :
Use explosion-proof ventilation that is adequate to keep employee exposure to airborne concentrations below
exposure limits.
Other engineering controls :
Keep container tightly closed. Observe label precautions. Have emergency eye wash and safety shower present.
Personal protective equipment
Eye and face protection:
Wear safety glasses. Wear coverall chemical splash goggles and face shield when eye and face contact is possible.
Skin protection:
Wear impervious ( ie. butyl rubber, Neoprene) clothing to prevent any contact.
Respiratory protection:
A NIOSH/MSHA air purifying respirator with an organic vapor cartridge or a positive pressure air supplied respirator as
exposure levels dictate.
