HANDLING AND STORAGE
7.1. Safe ‐ handling precautions
Safe use of the product:
The product must be handled in accordance with good industrial hygiene and safety practices.
Only experienced and properly instructed persons can manipulate gases under pressure.
Do not smoke while handling the product.
Use only specific equipment that are suitable for the product and for the operating pressure and temperature. In case of doubt, please contact
the supplier.
Do not breathe the gas.
Don’t release the product in the atmosphere.
You must ensure sufficient air exchange and/or suction.
Do not use direct flame or electric heating to increase internal pressure.
Do not remove or render illegible the affixed supplier identification labels.
Do not undergo any pressure test with the air /HFC ‐ 134a mixtures.
Gas ‐ air can form a combustible mixture at pressures higher than the atmospheric one when the volume ratio exceeds 60%.
Storage: Keep the unit away from incompatible products such as: explosive, flammable materials, Organic peroxide

PHYSICAL AND CHEMICAL PROPERTIES
9.1. Basic information about the Physical and Chemical properties
.
Aspet: Physical state at 20°C / 101.3kPa: Colorless liquefied gas.
Odor: Similar to ether.
Olfactory threshold: The olfactory threshold is subjective and inadequate to warn of overexposure.
Melting point ‐ 101°C
Boiling point: ‐ 26.5°C
Ignition point: Not flammable
Critical temperature [°C] 101°C
Relative density, gas (air = 1): 3,6
Water solubility: 1930 mg/l
9.2. Other information
Gas/vapor more heavier than air. May accumulate in confined spaces, particularly at or below ground level.
STABILITY AND REACTIVITY
Stability: No reactivity if used with the appropriate instructions.
Incompatible materials:
Humidity.
Refer to ISO 11114 standard for further information on material compatibility.
Hazardous decomposition products: Halogen acids, carbon dioxide (CO
2
), carbon monoxide, fluorocarbons, carbonyl halides.
Dangerous reactions:
The product is not flammable in contact with air under normal conditions of temperature and pressure. Under pressure with air or oxygen, the
mixture can become flammable. Some mixtures of HCFC or HFC and chlorine may become flammable or reactive under certain conditions.
TOXICOLOGICAL INFORMATION
