COMPANY ADDRESS: EMERGENCY TELEPHONE NUMBERS:
iGas USA, Inc. (800) 424-9300 (CHEMTREC, transportation and spills)
8105 Anderson Rd
Tampa, FL 33634
PRODUCT NAME : R-507
CHEMICAL NAME : AZ-50
PRODUCT USE : Refrigerant
PRODUCT CODE : n/a
SECTION 2 - HAZARDS IDENTIFICATION SUMMARY
(As defined by OSHA Hazard Communication Standard, 29 CFR 1910.1200)
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: AZ-50 (R-507) is low in acute toxicity in animals. When oxygen levels
in the 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.

Trace impurities and additional material names not listed above may also appear in Section 15 toward the end of the
MSDS. These materials may be listed for local “Right-To-Know” compliance and for other reasons.
SECTION 4 - FIRST AID MEASURES
First Aid responders should use protective equipment in Section 8 if there is a potential for exposure to product.
IF SWALLOWED: 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.
IF ON SKIN OR CLOTHING: 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.
IF IN 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.
IF INHALED: 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).
Have a product container or label with you when calling a poison control center or doctor, or going for treatment.
NOTE 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.

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, NIOSHapproved 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.
SECTION 6 - ACCIDENTAL RELEASE MEASURES
(Always wear recommended personal protective equipment.) Evacuate unprotected personnel. Protected personnel
should remove ignition sources and shut off leak, if without risk, and provide ventilation. Unprotected personnel
should not return 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.
SECTION 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. AZ-50 (R-507) should not be mixed with air above atmospheric pressure for leak testing
or any other purpose.
STORAGE RECOMMENDATIONS: Store in a cool, well-ventilated area of low fire risk and out of direct sunlight.
Protect cylinder and its fittings from physical damage. Storage in subsurface locations should be avoided. Close
valve tightly after use and when empty.

ENGINEERING CONTROLS: Provide local ventilation at filling zones and areas where leakage is probable.
Mechanical (general) ventilation may be adequate for other operating and storage areas.
PERSONAL PROTECTIVE EQUIPMENT SKIN PROTECTION: Skin contact with refrigerant may cause frostbite.
General work clothing and gloves (leather) should provide adequate protection. If prolonged contact with the liquid
or gas is anticipated, insulated gloves constructed of PVA, neoprene or butyl rubber should be used. Any
contaminated clothing should be promptly removed and washed before reuse.
EYE PROTECTION: For normal conditions, wear safety glasses. Where there is reasonable probability of liquid
contact, wear chemical safety goggles.
RESPIRATORY PROTECTION: None generally required for adequately ventilated work situations. For accidental
release or non-ventilated situations, or release into confined space, where the concentration may be above the PEL
of 1,000 ppm, use a self-contained, NIOSH-approved breathing apparatus or supplied air respirator. For escape:
use the former or a NIOSH-approved gas mask with organic vapor canister.
