STORAGE AND HANDLING
Care should be taken not to expose the product to high temperature
conditions, direct sunlight, ignition sources, oxidizing agents, alkalis or
acids. This might cause uncontrollable polymerization of the product
with the generation of heat. Storage and handling should be in stainless
steel, amber glass, amber polyethylene or baked phenolic lined
containers. Procedures that remove or displace oxygen from the material
should be avoided. Do not store this material under an oxygen free
atmosphere. Dry air is recommended to displace material removed from
the container. Wash thoroughly after handling. Keep container tightly
closed. Use with adequate ventilation.
