Storage Conditions

Keep container tightly closed in a dry and well-ventilated place. Containers which are opened must be carefully resealed and kept upright to prevent leakage. Recommended storage temperature 2 - 8 deg C. Air and moisture sensitive. Light sensitive. Store under inert gas. Over time, pressure may increase causing containers to burst.
Vinylidene chloride must be stored in tanks that have nickel, baked phenolic, or glass linings.
Store in a flammable liquid storage area or approved cabinet away from ignition sources and corrosive and reactive materials. May form peroxides in storage. High concentrations cause a deficiency of oxygen with the risk of unconsciousness or death. Check that oxygen content is at least 19% before entering storage or spill area. A regulated, marked area should be established where this chemical is handled, used, or stored in compliance with OSHA Standard 1910.1045. ... Prior to working with this chemical you should be trained on its proper handling and storage. Before entering confined space where this chemical may be present, check to make sure that an explosive concentration is not present. Vinylidene chloride must be stored to avoid contact with oxidizers, such as perchlorates, peroxides, permanganates, chlorates, and nitrates, and strong acids, such as hydrochloric, sulfuric, and nitric, since violent reactions occur. Store in tightly closed containers in a cool, well-ventilated area away from sources of heat. Protect storage containers from physical damage. Sources of ignition, such as smoking and open flames, are prohibited where vinylidene chloride is handled, used, stored. Metal containers involving the transfer of 5 gallons or more of vinylidene chloride should be grounded and bonded. Drums must be equipped with self-closing valves, pressure vacuum bungs, and flame arresters. Use only nonsparking tools and equipment, especially when opening and closing containers of vinylidene chloride. Wherever vinylidene chloride is used, handled, manufactured, or stored, use explosion-proof electrical equipment and fittings. Procedures for handling, use, and storage of cylinders should be in compliance with OSHA 1910.101 and 1910.169, as with the recommendations of the Compressed Gas Association.
Store in a cool, dry, well-ventilated location. Do not store in aluminum. Separate from air, light, heat, strong oxidizing materials. Outside or detached storage is preferred. Inside storage should be in a standard flammable liquids storage warehouse, room, or cabinet.
