Methods for cleaning up: Evaporates.
7. Handling and storage
Handling: Technical measures / precautions: Provide sufficient air
exchange and/or exhaust in work rooms. Safe handling advice: Use
only in well–ventilated areas. Do not breath vapours or spray mist.
System leak testing: Dot not pressure test any system with
air/HFC–134a mixtures. Can form a combustible mixture with air at
pressures above atmospheric when air concentration exceeds 60% by
volume.
Storage: Technical measures/Storage conditions: Keep tightly closed
in a dry, cool and well–ventilated place. Incompatible products:
Explosive, flammable materials. Organic peroxide. Packaging
material: Store in original container.
8. Exposure controls / personal protection
Engineering measures: Ensure adequate ventilation, especially in
confined areas.
Control parameters: DuPont’s acceptable exposure limit: AEL(8–h
and 12–h TWA) = 1000 ml/m

; DuPont (1995).
Personal protection equipment: Respiratory protection: For rescue
and maintenance work in CFC–tanks use self–contained breathing
apparatus. Vapours are heavier than air and can cause suffocation by
reducing available for breathing. Eye protection: safety glasses. Hand
protection: rubber gloves. Hygiene measures: Do not smoke.
9. Physical and chemical properties
Form: liquefied gas
Colour: colourless

10.Stability and reactivity
Stability: No decomposition if used as directed.
Materials to avoid: Alkali metals, alkaline earth metals, powdered
metal salts, powdered Al, Zn, Be, etc.
Hazardous composition products: hydrogen halides, traces of
carbonyl halides.
11.Toxicological information
Acute toxicity: ALC/inhalation/4h/rat = 567 ml/l.
Local effects: Concentrations substancially above the OEL value may
cause narcotic effects. Inhalation of decomposition products in high
concentration may cause shortness of breath (lung oedema).
Long term toxicity: Did not show carcinogenic, teratogenic or
mutagenic effects in animal experiments.
Special effects: Rapid evaporation of the liquid may cause frostbite.
12.Ecological information
Exotoxicity effects: Halocarbon global warming potential; HGWP;
(R–11 = 1) = 0.28. Ozone depletion potential; ODP; (R11 = 1) = 0.
13.Disposal considerations
Waste from residues / unused products: Can be used after
redonditioning.
Contaminated packaging: Empty pressure vessels should be
returned to the supplier.
