For Containment: Stop leak, if possible without risk. As an immediate precautionary measure, isolate spill or leak area in all
directions.
Methods for Cleaning Up: Stop the source of the release, if safe to do so. Consider the use of water spray to disperse vapors. Isolate
the area until gas has dispersed. Ventilate and gas test area before entering. Contact competent authorities after a spill.
6.4. Reference to Other Sections
See Section 8 for exposure controls and personal protection and Section 13 for disposal considerations.
SECTION 7: HANDLING AND STORAGE
7.1. Precautions for Safe Handling
Additional Hazards When Processed: Handle empty containers with care because residual vapors are flammable. Ruptured
cylinders may rocket. Do not pressurize, cut, or weld containers. Ensure adequate ventilation. Asphyxiating gas at high
concentrations.
Precautions for Safe Handling: Wash hands and other exposed areas with mild soap and water before eating, drinking or smoking
and when leaving work. Avoid prolonged contact with eyes, skin and clothing. Do not breathe gas.
Hygiene Measures: Handle in accordance with good industrial hygiene and safety procedures.
7.2. Conditions for Safe Storage, Including Any Incompatibilities
Technical Measures: Comply with applicable regulations. Proper grounding procedures to avoid static electricity should be followed.
Storage Conditions: Keep container closed when not in use. Store in a dry, cool place. Keep/Store away from direct sunlight,
extremely high or low temperatures and incompatible materials. Keep in fireproof place. Cylinders should be stored upright with
valve protection cap in place and firmly secured to prevent falling. Incompatible Materials: Strong acids, strong bases, strong
oxidizers.
7.3. Specific End Use(s)
Refrigerant. For professional use only.
