2. HAZARDS IDENTIFICATION

CLASSIFICATION: Gases under pressure, Liquefied Gas
SIGNAL WORD: WARNING
HAZARD STATEMENT: Contains gas under pressure, may explode if heated

SYMBOL: Gas Cylinder

PRECAUTIONARY STATEMENT: STORAGE: Protect from sunlight, store in a well-ventilated place

EMERGENCY OVERVIEW: Colorless, volatile liquid with ethereal and faint sweetish odor. Non-flammable
material. Overexposure may cause dizziness and loss of concentration. At higher levels, CNS depression and
cardiac arrhythmia may result from exposure. Vapors displace air and can cause asphyxiation in confined

spaces. At higher temperatures, (>250 C), decomposition products may include Hydrofluoric Acid (HF) and
carbonyl halides.

POTENTIAL HEALTH HAZARDS

SKIN: Irritation would result from a defatting action on tissue. Liquid contact could cause frostbite.

EYES: Liquid contact can cause severe irritation and frostbite. Mist may irritate.

INHALATION: R-410A is low in acute toxicity in animals. When oxygen levels in air are reduced to 12-14% by

displacement, symptoms of asphyxiation, loss of coordination, increased pulse rate and deeper
respiration will occur. At high levels, cardiac arrhythmia may occur.

INGESTION: Ingestion is unlikely because of the low boiling point of the material. Should it occur, discomfort in

the gastrointestinal tract from rapid evaporation of the material and consequent evolution of gas
would result. Some effects of inhalation and skin exposure would be expected.

DELAYED EFFECTS: None known.

4. FIRST AID MEASURES

SKIN: Promptly flush skin with water until all chemical is removed. If there is evidence of frostbite, bathe (do not rub) with

lukewarm (not hot) water. If water is not available, cover with a clean, soft cloth or similar covering. Get medical
attention if symptoms persist.

EYES: Immediately flush eyes with large amounts of water for at least 15 minutes (in case of frostbite water should be

lukewarm, not hot) lifting eyelids occasionally to facilitate irrigation. Get medical attention if symptoms persist.

INHALATION: Immediately remove to fresh air. If breathing has stopped, give artificial respiration. Use oxygen as

required, provided a qualified operator is available. Get medical attention. Do not give epinephrine
(adrenaline).

INGESTION: Ingestion is unlikely because of the physical properties and is not expected to be hazardous. Do not induce

vomiting unless instructed to do so by a physician.

ADVICE TO PHYSICIAN: Because of the possible disturbances of cardiac rhythm, catecholamine drugs, such as

epinephrine, should be used with special caution and only in situations of emergency
life support. Treatment of overexposure should be directed at the control of symptoms and
the clinical conditions.

FLAMMABLE PROPERTIES

FLASH POINT: Gas, not applicable per DOT regulations
FLASH POINT METHOD: Not applicable

AUTOIGNITION TEMPERATURE: >750 C

UPPER FLAME LIMIT (volume % in air): None by ASTM D-56-82
LOWER FLAME LIMIT (volume % in air): None by ASTM E-681
FLAME PROPAGATION RATE (solids): Not applicable
OSHA FLAMMABILITY CLASS: Not applicable

EXTINGUISHING MEDIA:

Use any standard agent – choose the one most appropriate for type of surrounding fire (material itself is not
flammable)

UNUSUAL FIRE AND EXPLOSION HAZARDS:
R-410A is not flammable at ambient temperatures and atmospheric pressure. However, this material will become
combustible when mixed with air under pressure and exposed to strong ignition sources.

Contact with certain reactive metals may result in formation of explosive or exothermic reactions under specific
conditions (e.g. very high temperatures and/or appropriate pressures).

SPECIAL FIRE FIGHTING PRECAUTIONS/INSTRUCTIONS:
Firefighters should wear self-contained, NIOSH-approved breathing apparatus for protection against possible toxic
decomposition products. Proper eye and skin protection should be provided. Use water spray to keep fire-exposed
containers cool.

6. ACCIDENTAL RELEASE MEASURES

IN CASE OF SPILL OR OTHER RELEASE: (Always wear recommended personal protective equipment.)

Evacuate unprotected personnel. Product dissipates upon release. Protected personnel should remove ignition
sources and shut off leak, if without risk, and provide ventilation. Unprotected personnel should not return to the
affected area until air has been tested and determined safe, including low-lying areas.

Spills and releases may have to be reported to Federal and/or local authorities. See Section 15 regarding reporting
requirements.

7. HANDLING AND STORAGE

NORMAL HANDLING: (Always wear recommended personal protective equipment.)

Avoid breathing vapors and liquid contact with eyes, skin or clothing. Do not puncture or drop cylinders, expose
them to open flame or excessive heat. Use authorized cylinders only. Follow standard safety precautions for
handling and use of compressed gas cylinders.
