3.2 POTENTIAL HEALTH EFFECTS

3M MATERIAL SAFETY DATA SHEET HFE-7500 3M (TM) NOVEC (TM) Engineered Fluid 10/08/2003

Eye Contact:
Contact with the eyes during product use is not expected to result in significant irritation.

Skin Contact:
Contact with the skin during product use is not expected to result in significant irritation.

Inhalation:
If thermal decomposition occurs:
Respiratory Effects: Signs/symptoms may include cough, sneezing, shortness of breath, chest tightness, nasal discharge, and
wheezing.

Ingestion:
No health effects are expected.

3.3 POTENTIAL ENVIRONMENTAL EFFECTS

This substance has chemical moieties that are resistant to biodegradation and is likely to only undergo partial biodegradation in the
environment.

The high potential of this substance to move from water to the atmosphere means its potential to bioconcentrate is likely to disappear
rapidly from aerobic environments.

AQUATIC TOXICITY: Testing results indicate that this product has insignificant toxicity to aquatic organisms at its saturation point
(Lowest LC50, EC50, or IC50 > substance water solubility).

This substance is highly volatile and has a high Henry's Law constant and is thus expected to move rapidly through vaporization from
solution in an aquatic compartment or from a soil surface in a terrestrial compartment to the atmosphere.

ATMOSPHERIC FATE:
Zero Oxone Depletion Potential (ODP).
Atmospheric Lifetime: ~2.2 years (based on reaction with OH radicals)
Global Warming Potential (GWP): 90 (100 year ITH) (IPCC1995 method)
Global Warming Potential (GWP): 100 (100 year ITH) (IPCC2001 method)

SECTION 4: FIRST AID MEASURES
4.1 FIRST AID PROCEDURES

The following first aid recommendations are based on an assumption that appropriate personal and industrial hygiene practices are
followed.

Eye Contact: Flush eyes with large amounts of water. Get medical attention.

Skin Contact: Wash affected area with soap and water. If signs/symptoms develop, get medical attention.

Inhalation: If signs/symptoms develop, remove person to fresh air. If signs/symptoms develop, get medical attention.

If Swallowed: Do not induce vomiting. Give victim two glasses of water. Never give anything by mouth to an unconscious person.
If signs/symptoms develop, get medical attention.

5.2 EXTINGUISHING MEDIA
Material will not burn.

5.3 PROTECTION OF FIRE FIGHTERS

Special Fire Fighting Procedures: Water may be used to blanket the fire. Exposure to extreme heat can give rise to thermal
decomposition. Wear full protective clothing, including helmet, self-contained, positive pressure or pressure demand breathing
apparatus, bunker coat and pants, bands around arms, waist and legs, face mask, and protective covering for exposed areas of the head.

Unusual Fire and Explosion Hazards: No unusual fire or explosion hazards are anticipated. No unusual effects are anticipated
during fire extinguishing operations. Avoid breathing the products and substances that may result from the thermal decomposition of
the product or the other substances in the fire zone. Keep containers cool with water spray when exposed to fire to avoid rupture.

Note: See STABILITY AND REACTIVITY (SECTION 10) for hazardous combustion and thermal decomposition
information.

SECTION 6: ACCIDENTAL RELEASE MEASURES
Accidental Release Measures: Observe precautions from other sections. Call 3M- HELPS line (1-800-364-3577) for more
information on handling and managing the spill. Evacuate unprotected and untrained personnel from hazard area. The spill should be
cleaned up by qualified personnel. Ventilate the area with fresh air. Contain spill. Working from around the edges of the spill
inward, cover with bentonite, vermiculite, or commercially available inorganic absorbent material. Mix in sufficient absorbent until it
appears dry. Collect as much of the spilled material as possible. Clean up residue. Place in a metal container approved for
transportation by appropriate authorities. Seal the container. Dispose of collected material as soon as possible.

In the event of a release of this material, the user should determine if the release qualifies as reportable according to
local, state, and federal regulations.

SECTION 7: HANDLING AND STORAGE
7.1 HANDLING
Avoid skin contact with hot material. For industrial or professional use only. Contents may be under pressure, open carefully. No
smoking: Smoking while using this product can result in contamination of the tobacco and/or smoke and lead to the formation of the
hazardous decomposition products mentioned in the Reactivity Data section of this MSDS. Store work clothes separately from other
clothing, food and tobacco products. Use general dilution ventilation and/or local exhaust ventilation to control airborne exposures to
below Occupational Exposure Limits. If ventilation is not adequate, use respiratory protection equipment. Avoid continuous
exposure of the material to extreme conditions of heat, i.e., above 150 C (welding, open flame, misuse or equipment failure). Avoid
exceeding a watt density of 50 watts/inch2 from a heater surface. Continuous exposure to 150 C results in very slight decomposition
of this product and therefore, is a very conservative use temperature threshold. Applications involving exposure of the fluid to
temperatures exceeding 150 C or watt densities exceeding 50 watts/inch2 have been safely implemented. Applications which may
exceed these use parameters should be reviewed with 3M Technical Service.

3M MATERIAL SAFETY DATA SHEET HFE-7500 3M (TM) NOVEC (TM) Engineered Fluid 10/08/2003

7.2 STORAGE
Keep container tightly closed. Keep container in well-ventilated area. Store away from heat. Store away from strong bases.

SECTION 8: EXPOSURE CONTROLS/PERSONAL PROTECTION
8.1 ENGINEERING CONTROLS
Use with appropriate local exhaust ventilation. Provide local exhaust ventilation at transfer points. Provide appropriate local exhaust
when product is heated. For those situations where the fluid might be exposed to extreme overheating due to misuse or equipment
failure, use with appropriate local exhaust ventilation sufficient to maintain levels of thermal decomposition products below their
exposure guidelines.

8.2 PERSONAL PROTECTIVE EQUIPMENT (PPE)

8.2.1 Eye/Face Protection
Avoid eye contact.
The following eye protection(s) are recommended: Safety Glasses with side shields.

8.2.2 Skin Protection
Avoid skin contact with hot material. Wear appropriate gloves, such as Nomex, when handling this material to prevent thermal burns.

Select and use gloves and/or protective clothing to prevent skin contact based on the results of an exposure assessment. Consult with
your glove and/or protective clothing manufacturer for selection of appropriate compatible materials.
Gloves made from the following material(s) are recommended: Nitrile Rubber, Polyethylene/Ethylene Vinyl Alcohol.

8.2.3 Respiratory Protection
Avoid breathing of vapors, mists or spray. Under normal use conditions, airborne exposures are not expected to be significant enough
to require respiratory protection.

Select one of the following NIOSH approved respirators based on airborne concentration of contaminants and in accordance with
OSHA regulations: Half facepiece or fullface air-purifying respirator with organic vapor cartridges. Consult the current 3M
Respiratory Selection Guide for additional information or call 1-800-243-4630 for 3M technical assistance. If thermal decomposition
products are expected, use fullface supplied air respirator.

8.2.4 Prevention of Swallowing
Do not eat, drink or smoke when using this product. Wash exposed areas thoroughly with soap and water.

SECTION 16: OTHER INFORMATION
NFPA Hazard Classification
Health: 3 Flammability: 1 Reactivity: 0 Special Hazards: None

National Fire Protection Association (NFPA) hazard ratings are designed for use by emergency response personnel to address the hazards that are
presented by short-term, acute exposure to a material under conditions of fire, spill, or similar emergencies. Hazard ratings are primarily based on the
inherent physical and toxic properties of the material but also include the toxic properties of combustion or decomposition products that are known to
be generated in significant quantities. The hazard ratyings assigned to this product are based on the properties of combustion or decomposition
products that can occur in an uncontrolled fire situation.

HMIS Hazard Classification
Health: 0 Flammability: 1 Reactivity: 0 Protection: X - See PPE section.
Hazardous Material Identification System (HMIS(r)) hazard ratings are designed to inform employees of chemical hazards in the workplace. These
ratings are based on the inherent properties of the material under expected conditions of normal use and are not intended for use in emergency
situations. HMIS(r) ratings are to be used with a fully implemented HMIS(r) program. HMIS(r) is a registered mark of the National Paint and
Coatings Association (NPCA).
