Safety and Handling
Unisolv-1234yf is classified as an extremely flammable gas and a liquefied gas under pressure. Containers may rupture or explode if heated. Keep the product away from heat, sparks, open flames, hot surfaces, and other ignition sources.
Adequate Ventilation
Use only with adequate ventilation. Released gas may displace oxygen and cause rapid suffocation.
Ignition Control
Keep away from sparks, flames, hot surfaces, and other ignition sources. Do not smoke near the product.
Cold-Contact Protection
Contact with rapidly evaporating liquid may freeze tissue and cause burns similar to frostbite.
Pressure-Rated Equipment
Use equipment rated for cylinder pressure and close the valve after each use and when the container is empty.
Storage Information
Store Unisolv-1234yf in a segregated, approved, dry, cool, and well-ventilated area away from direct sunlight and incompatible materials. Eliminate all ignition sources and keep containers tightly closed until ready for use.
Temperature Control
Do not store above 50°C, or 122°F. Cylinder temperatures should not exceed 52°C, or 125°F.
Upright Storage
Store cylinders upright with valve-protection caps in place.
Secure Cylinders
Secure cylinders to prevent them from falling or being knocked over.
Physical Protection
Do not drag, roll, slide, or drop cylinders. Use a suitable hand truck when moving them.
