The user must be a fully qualified and experienced laboratory or chemical production worker to handle these reagents. All users must be aware of the hazardous nature of many of these products. The material safety data sheet (MSDS), which is provided with each order, must be read and understood by the user prior to starting any work with the product contained in a UN-Pac container. In general, handle these products only under an inert atmosphere and exercise caution to prevent inhalation of vapors or direct contact with the skin. Operators must wear appropriate clothing with long sleeves, chemical resistant gloves, goggles, and full faceshield. Additional personal protective equipment must be used as required. In case of contact, immediately flush eyes or skin with water for at least 15 minutes while removing contaminated clothing and shoes. Seek medical attention promptly.

In case of fire, use a dry chemical extinguisher; do not use water with moisture reactive products. Store UN-Pac containers upright in a cool location, away from heat and direct sunlight. Refrigerate if necessary.

During all nitrogen-pressure transfer, the flowing liquid can generate a static charge. Therefore, the UN-Pac container and receiver must be connected to a suitable ground. Aldrich offers a 6-ft length of flat braided bare cable with copper clips at each end which makes a convenient grounding strap (Z15,030-4).

Technical experts are available by telephone to answer your questions regarding the proper handling of products packaged in UN-Pac containers. Contact Aldrich immediately if an inadvertent deviation from the recommended transfer procedure occurs during use of a UN-Pac container.
