REFRIGERANT SAFETY DATA SHEET
Name:
R134a (100% ,1,1,2-Tetrafluoroethane).
RISK INDICATIONS
Major risks:
Asphyxia.
Specific risks:
The rapid evaporation may cause freezing.
It can cause cardiac arrhythmia.
FIRST AID
General informations:
Never give anything by mouth to an unconscious person.
Inhalation:
Move to fresh air.
Oxygen or artificial respiration if necessary.
Do not administer adrenaline or similar drugs.
Eyes contact:
Rinse carefully with water for at least 15 minutes and consult a doctor.
Contact with skin:
Wash immediately with plenty of water.
Take off immediately the contaminated clothing.
FIRE PREVENTION
Extinguishing Media:
Whatever.
Specific risks:
Increase in pressure.
Specific methods:
Use water spray to cool containers
Special protective equipments:
Use breathing apparatus in confined spaces.
ACCIDENTAL RELEASE ACTIONS
Personal precautions:
Evacuate personnel to safe areas.
Provide
adequate
ventilation.
Use personal protective equipment.
Environmental precautions:
Evaporate.
Cleaning method:
Evaporate.
HANDLING AND STORAGE
Manipulation
actions/technical precautions:
Provide sufficient air exchange and/or suction in workplaces.
Recommendations for safe use:
Do not breathe vapors or aerosol.
Do not apply any testing pressure with air/HFC-134a mixtures. It may form with the air a fuel mixture at pressures greater than atmospheric
greater than atmospheric pressure when the volume ratio exceeds 60%.
Storage:
Close tightly and store in a cool, dry and well ventilated place.
Store in original container. Incompatible products: explosive, flammable materials, organic peroxide.
EXPOSURE CONTROL / PERSONAL PROTECTION
Control parameters:
AEL (8-h e 12-h TWA) = 1000 ml/m3.
Respiratory protection:
For rescue and maintenance operation in storage tanks use self-contained respirator apparatus.
The vapors are heavier than air and can cause suffocation by reducing oxygen available for breathing.
Eyes protection:
Total safety glasses.
Protection of hands:
Rubber gloves.
Hygiene measures:
Do not smoke.
PHYSICAL AND CHEMICAL PROPERTIES
Colour:
Colourless liquefied gas.
Odor:
Similar to ether.
Boiling point:
-26.5°C at atmospheric pressure.
Lighting point:
It does not ignite.
Density:
1.21 kg/l at 25°C.
Solubility in water (wt %):
0.15
STABILITY AND REACTIVITY
Stability:
No reactivity when used with the appropriate instructions.
Materials to avoid:
Alkali metals, alkaline earth metals, powdered metals, metal salts.
Dangerous decomposition products:
Halogen acids, carbon dioxide (CO2), carbon monoxide, fluorocarbons, carbonyl halides.
Dangerous reactions:
The product is not flammable in contact with air under ambient conditions of temperature and pressure. When pressurized with air or oxygen
the mixture may become flammable. Certain mixtures of HCFCs or HFCs with chlorine may become flammable or reactive under certain conditions.
TOXICOLOGICAL INFORMATION
Acute toxicity:
LC50/ inhalation /4 hours/on rat >2085 mg/m3
Local effects:
Concentrations substantially above the TLV (1000 ppm) may cause narcotic effects.
Inhalation of decomposed products at high concentrations may cause respiratory failure (pulmonary edema).
Long term toxicity:
Did not show carcinogenic, teratogenic or mutagenic effects in animal experiments. It can cause cardiac arrhythmia.
Threshold limit for the cardiac sensitivity: 312975 mg/m3. Threshold limit for the anesthetic effects: 834600 mg/m3.
