The above listed potential effects of overexposure are based on actual data, results of studies performed upon similar compositions,
component data and/or expert review of the product. Please refer to Section 11 for the detailed toxicology information.
3. COMPOSITION/INFORMATION ON INGREDIENTS
CAS Number Wt % Component Name
8052-41-3 > 60.0 Stoddard solvent
108-11-2 3.0 - 7.0 4-methyl-2-pentanol
The above components are hazardous as defined in 29 CFR 1910.1200.
4. FIRST AID MEASURES
Eye: Immediately flush with water for 15 minutes.
Skin: Remove from skin and wash thoroughly with soap and water or waterless cleanser. Get
medical attention if irritation or other ill effects develop or persist.
Inhalation: Remove to fresh air. Get medical attention if ill effects persist.
Oral: Get immediate medical attention. Only induce vomiting at the instructions of a physician.
Never give anything by mouth to an unconscious person.
Notes to Physician: Treat according to person's condition and specifics of exposure.
5. FIRE FIGHTING MEASURES
Flash Point: 103.1 癋 / 39.5 癈 (Closed Cup)
Autoignition Temperature: Not determined.
Flammability Limits in Air: Not determined.
Extinguishing Media: On large fires use dry chemical, foam or water spray. On small fires use carbon dioxide
(CO2), dry chemical or water spray. Water can be used to cool fire exposed containers.
Fire Fighting Measures: Self-contained breathing apparatus and protective clothing should be worn in fighting large
fires involving chemicals. Use water spray to keep fire exposed containers cool. Determine
the need to evacuate or isolate the area according to your local emergency plan.
Unusual Fire Hazards: Static electricity will accumulate and may ignite vapors. Prevent a possible fire hazard by
bonding and grounding or inert gas purge.

6. ACCIDENTAL RELEASE MEASURES
Containment/Clean up: Remove possible ignition sources. Determine whether to evacuate or isolate the area
according to your local emergency plan. Observe all personal protection equipment
recommendations described in Sections 5 and 8. For large spills, provide diking or other
appropriate containment to keep material from spreading. If diked material can be pumped,
store recovered material in appropriate container. Clean up remaining materials from spill
with suitable absorbant. Clean area as appropriate since spilled materials, even in small
quantities, may present a slip hazard. Final cleaning may require use of steam, solvents or
detergents. Dispose of saturated absorbant or cleaning materials appropriately, since
spontaneous heating may occur. Local, state and federal laws and regulations may apply to
releases and disposal of this material, as well as those materials and items employed in the
cleanup of releases. You will need to determine which federal, state and local laws and
regulations are applicable. Sections 13 and 15 of this MSDS provide information regarding
certain federal and state requirements.
Note: See section 8 for Personal Protective Equipment for Spills. Call (989) 496-5900, if additional information is
required.
7. HANDLING AND STORAGE
Use with adequate ventilation. Avoid eye exposure. Avoid skin contact. Do not breathe vapor, mist, dust, or fumes.
Keep container closed. Do not take internally.
Static electricity will accumulate and may ignite vapors. Prevent a possible fire hazard by bonding and grounding or inert
gas purge. Keep container closed and away from heat sparks and flame.
8. EXPOSURE CONTROLS / PERSONAL PROTECTION

Eyes: Use chemical worker's goggles.
Skin: Wash at mealtime and end of shift. Contaminated clothing and shoes should be removed as
soon as practical and thoroughly cleaned before reuse. Chemical protective gloves are
recommended.
Suitable Gloves: Silver Shield(R). 4H(R).
Inhalation: Use respiratory protection unless adequate local exhaust ventilation is provided or exposure
assessment demonstrates that exposures are within recommended exposure guidelines. IH
personnel can assist in judging the adequacy of existing engineering controls.
Suitable Respirator: General and local exhaust ventilation is recommended to maintain vapor exposures below
recommended limits. Where concentrations are above recommended limits or are unknown,
appropriate respiratory protection should be worn. Follow OSHA respirator regulations (29
CFR 1910.134) and use NIOSH/MSHA approved respirators.
Personal Protective Equipment for Spills
Eyes: Use full face respirator.
Skin: Wash at mealtime and end of shift. Contaminated clothing and shoes should be removed as
soon as practical and thoroughly cleaned before reuse. Chemical protective gloves are
recommended.
Inhalation/Suitable Respiratory protection recommended. Follow OSHA Respirator Regulations (29 CFR
Respirator: 1910.134) and use NIOSH/MHSA approved respirators. Protection provided by air purifying
respirators against exposure to any hazardous chemical is limited. Use a positive pressure air
supplied respirator if there is any potential for uncontrolled release, exposure levels are
unknown, or any other circumstance where air purifying respirators may not provide adequate
protection.
Precautionary Measures: Avoid eye exposure. Avoid skin contact. Do not breathe vapor, mist, dust, or fumes. Keep
container closed. Do not take internally. Use reasonable care.
Note: These precautions are for room temperature handling. Use at elevated temperature or aerosol/spray applications may require
added precautions.
