R134a (100% ,1,1,2-Tetrafluoroethane).
Asphyxia.
The rapid evaporation may cause freezing.
It can cause cardiac arrhythmia.
Never give anything by mouth to an unconscious person.
Move to fresh air.
Oxygen or artificial respiration if necessary.
Do not administer adrenaline or similar drugs.
Rinse carefully with water for at least 15 minutes and consult a doctor.
Wash immediately with plenty of water.
Take off immediately the contaminated clothing.
Whatever.
Increase in pressure.
Use water spray to cool containers
Use breathing apparatus in confined spaces.
Evacuate personnel to safe areas.
Provide adequate ventilation.
Use personal protective equipment.
Evaporate.
Evaporate.
Provide sufficient air exchange and/or suction in workplaces.
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%.
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
AEL (8-h e 12-h TWA) = 1000 ml/m3.
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.
Total safety glasses.
Rubber gloves.
Do not smoke.
PHYSICAL AND CHEMICAL PROPERTIES
Colourless liquefied gas.
Similar to ether.
-26.5°C at atmospheric pressure.
It does not ignite.
1.21 kg/l at 25°C.
0.15
No reactivity when used with the appropriate instructions.
Alkali metals, alkaline earth metals, powdered metals, metal salts.
Halogen acids, carbon dioxide (CO2), carbon monoxide, fluorocarbons, carbonyl halides.
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
LC50/ inhalation /4 hours/on rat >2085 mg/m3
Concentrations substantially above the TLV (1000 ppm) may cause narcotic effects.
Inhalation of decomposed products at high concentrations may cause respiratory failure (pulmonary edema).
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.
