Tests were conducted using water for liquid containers, sand and sawdust for solids containers, or water and anti-freeze mixtures for plastic drums used to contain liquids.  Your product may adversely affect container materials, bung threads or closing devices.  Product compatibility with the container is a shipper's responsibility.

These instructions for container closure are based upon the closure methods used to enable these containers to pass the United Nations test requirements as outlined by the UN marking on the package.

These closures recommendations do not take into account any hazards present in your facility or the handling, filling or shipping of your product.   The use of sparkless tools and proper safety equipment is recommended.   Consult your supervisor for your special safety precautions.

Any containers used for packing of hazardous materials should be inspected prior to filling and shipment.  Containers with obvious damage or deterioration should not be filled or shipped.
