7. HANDLING AND STORAGE
NORMAL HANDLING: Always wear recommended personal protective equipment.
Avoid breathing vapors and liquid contact with eyes, skin or clothing. Do not puncture or drop cylinders, expose
them to open flame or excessive heat. Use authorized cylinders only. Follow standard safety precautions for
handling and use of compressed gas cylinders. R-134A should not be mixed with air above atmospheric pressure
for leak testing or any other purpose.
STORAGE RECOMMENDATIONS:
Store in a cool, well-ventilated area of low fire risk and keep out of direct sunlight. Protect cylinder and its fittings
from physical damage. Storage in subsurface locations should be avoided. Close valve tightly after use and when
empty. Cylinder temperatures should not exceed 52° C (125° F).
8. EXPOSURE CONTROLS / PERSONAL PROTECTION
ENGINEERING CONTROLS: Provide local ventilation at filling zones and areas where leakage is probable.
Mechanical (general) ventilation may be adequate for other operating and storage areas.
PERSONAL PROTECTIVE EQUIPMENT
SKIN PROTECTION: Skin contact with refrigerant may cause frostbite. General work clothing and
gloves (leather) should provide adequate protection. If prolonged contact with the liquid or gas is
anticipated, insulated gloves constructed of PVA, neoprene or butyl rubber should be used. Any
contaminated clothing should be promptly removed and washed before reuse.
EYE PROTECTION:
For normal conditions, wear safety glasses. Where there is reasonable
probability of liquid contact, wear chemical safety goggles.
RESPIRATORY PROTECTION: None generally required for adequately ventilated work situations.
For accidental release or non-ventilated situations, or release into confined space, where the concentration
may be above the PEL of 1,000 ppm, use a self-contained, NIOSH- approved breathing apparatus or
supplied air respirator. For escape: use the former or a NIOSH-approved gas mask with organic vapor
canister.
ADDITIONAL RECOMMENDATIONS: Where contact with liquid is likely, such as in a spill or leak,
impervious boots and clothing should be worn. High dose-level warning signs are recommended for areas
of principle exposure. Provide eyewash stations and quick-drench shower facilities at convenient locations.
For tank cleaning operations, see OSHA regulations, 29 CFR 1910.132 and 29 CFR 1910.133.
