Section 2. Hazards Identification:
Emergency Overview Misuse or intentional inhalation abuse may lead to death without warning. Vapours are heavier than air and can cause suffocation by reducing oxygen available for breathing. Rapid evaporation of the liquid may cause frostbite.

Potential Health Effects:

• Skin: Contact with liquid or refrigerated gas can cause cold burns and frostbite.
• Eyes: Contact with liquid or refrigerated gas can cause cold burns and frostbite.
• Inhalation: Misuse or intentional inhalation abuse may cause death without warning symptoms, due to cardiac effects. Other symptoms potentially related to misuse or inhalation abuse are: Anaesthetic effects, Light-headedness, dizziness, confusion, incoordination, drowsiness, or unconsciousness, irregular heartbeat with a strange sensation in the chest, heart thumping, apprehension, feeling of fainting, dizziness or weakness. Vapours are heavier than air and can cause suffocation by reducing oxygen available for breathing.
• Target Organs Isobutane (<0.1% butadiene): Central nervous system

Carcinogenicity:
None of the components present in this material at concentrations equal to or greater than 0.1% are listed by IARC, NTP, or OSHA, as a carcinogen.

Section 4. First Aid Measures:

• Skin contact: In case of contact, immediately flush skin with plenty of water for at least 15 minutes. Take off all contaminated clothing immediately. Consult a physician. Wash contaminated clothing before re-use. Treat for frostbite if necessary by gently warming affected area.
• Eye contact: In case of contact, immediately flush eyes with plenty of water for at least 15 minutes. Consult a physician if necessary.
• Inhalation: Remove from exposure, lie down. Move to fresh air. Keep patient warm and at rest. Artificial respiration and/or oxygen may be necessary. Consult a physician.
• Ingestion: Is not considered a potential route of exposure.
• General advice: Never give anything by mouth to an unconscious person. When symptoms persist or in all cases of doubt seek medical advice.
• Notes to physician: Because of possible disturbances of cardiac rhythm, catecholamine drugs, such as epinephrine, that may be used in situations of emergency life support should be used with special caution.

Section 5. Firefighting Measures:
Flammable Properties:

• Flash point: does not flash
• Lower explosion limit: Method : None per ASTM E681
• Upper explosion limit: Method : None per ASTM E681
• Fire and Explosion Hazard: Cylinders are equipped with pressure and temperature relief devices, but may still rupture under fire conditions. Decomposition may occur. Contact of welding or soldering torch flame with high concentrations of refrigerant can result in visible changes in the size and colour of the torch flame.

DuPont™ ISCEON® MO59 (R-417A) is a non-ozonedepleting HFC Refrigerant best suited to replace R22 in existing small (<15 kW), direct expansion (DX), residential and commercial air conditioning (AC) equipment. Field experience has shown that ISCEON® MO59 provides performance that meets customer requirements in most properly retrofitted systems. ISCEON® MO59 provides lower cooling capacity, but better energy efficiency than R22 has been reported in many systems, while operating at significantly lower compressor discharge temperature and pressure. Actual performance depends on system design and operating conditions. ISCEON® MO59 is compatible with traditional and new lubricants; in most cases no change of lubricant type during retrofit is required. Minor equipment modifications (e.g., seal replacement) or expansion device adjustments may be required in some applications. Systems using ISCEON® MO59 are easy to service. For most systems, should a refrigerant loss occur, the charge can be completed without the need to remove any residual refrigerant, and the system will then operate normally. The cause of the refrigerant loss should be investigated and corrected as soon as is possible.

Note: When servicing critically charged systems, all of the refrigerant charge should be removed. This is the same practice recommended for HCFC-22.

The use of ISCEON® MO59 in the EU and EEA member countries is regulated under the terms of the Regulation 842/2006 (known as the “F Gas Regulation”), which requires regular leakage testing for systems using the designated substances. ISCEON® MO59 (R417A) is listed in the European Standard EN 378:2008 (Refrigerating and Heat Pump Systems – Safety and Environmental Requirements); Part 4 of this standard relates to retrofit activities.

Summary – Steps to Retrofit:
The following provides a summary of the basic retrofit steps for ISCEON® MO59.
(Detailed discussion of each step is provided in this bulletin.)

• Establish baseline performance with existing refrigerant and check for leaks. (See retrofit checklist (attached))
• Remove all of the old (R22 or other) refrigerant from the system into a recovery cylinder. Weigh the amount removed.
• Where practical replace the filter drier and critical elastomeric seals/gaskets.
• Evacuate system and check for leaks.
• Charge with ISCEON® MO59. • Remove liquid only from charging cylinder. • The initial charge amount should be approximately 85% of the standard charge for R22. The final charge amount is typically approximately 95%.
• Start up system, adjust charge size (unless liquid receiver or TXV present) to achieve optimum superheat.
• Monitor oil levels in compressor, if possible. Add oil as required to maintain proper levels
• Label system showing the refrigerant (and any replacement lubricant) used. Update system log-book.

Important Safety Information:
Like CFCs and HCFCs, ISCEON® 9 Series refrigerants are safe to use when handled properly. However, any refrigerant can cause injury or even death when mishandled. Please review the following guidelines before using any refrigerant.

• Do not work in high concentrations of refrigerant vapors. Always maintain adequate ventilation in the work area. Do not breathe vapors. Do not breathe lubricant mists from leaking systems. Ventilate the area well after any leak before attempting to repair equipment.
• Do not use handheld leak detectors to check for breathable air in enclosed working spaces. These detectors are not designed to determine if the air is safe to breathe. Use oxygen monitors to ensure adequate oxygen is available to sustain life.
