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. Determine the need to evacuate or isolate the area according to
your local emergency plan. Use water spray to keep fire exposed containers cool.

MOLYKOTE(R) 7409 ANTI-FRICTION COATING
Unusual Fire Hazards: Vapors are heavier than air and may travel to a source of ignition and flash back. Static
electricity will accumulate and may ignite vapors. Prevent a possible fire hazard by bonding
and grounding or inert gas purge.
Hazardous Decomposition Products
Thermal breakdown of this product during fire or very high heat conditions may evolve the following hazardous
decomposition products: Carbon oxides and traces of incompletely burned carbon compounds. Nitrogen oxides.
Formaldehyde. Sulfur oxides. Metal oxides.
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. Traces of benzene (carcinogen) may form if heated in air above 300 F (149 C). Provide
ventilation to control vapor exposure within inhalation guidelines when handling at elevated temperatures. Review the
OSHA benzene regulation for detailed information on safe handling requirements. Avoid eye exposure. Avoid skin
contact. Avoid breathing 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.

respirable fraction. ACGIH TLV: TWA 2 mg/m3 respirable
fraction.
Engineering Controls
Local Ventilation: Recommended.
General Ventilation: Recommended.
Personal Protective Equipment for Routine Handling
Eyes: Use chemical worker's goggles.
Skin: Wash at mealtime and end of shift. If skin contact occurs, change contaminated clothing as
soon as possible and thoroughly flush affected areas with cool water. Chemical protective
gloves are recommended.
Suitable Gloves: Butyl Rubber. Teflon(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. If skin contact occurs, change contaminated clothing as
soon as possible and thoroughly flush affected areas with cool water. 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. Avoid breathing vapor, mist, dust, or fumes. Keep
container closed. Do not take internally. Use reasonable care.

Comments: Traces of benzene (carcinogen) may form if heated in air above 300 F (149 C). Provide
ventilation to control vapor exposure within inhalation guidelines when handling at elevated
temperatures. Review the OSHA benzene regulation for detailed information on safe
handling requirements.
When heated to temperatures above 150 degrees C in the presence of air, product can form
formaldehyde vapors. Formaldehyde is a potential cancer hazard, a known skin and
respiratory sensitizer, and an irritant to the eyes, nose, throat, skin, and digestive system.
Safe handling conditions may be maintained by keeping vapor concentrations within the
OSHA Permissible Exposure Limit for formaldehyde.
Note: These precautions are for room temperature handling. Use at elevated temperature or aerosol/spray applications may require
added precautions.
