Lithium

Halon 1301, the suppression agent found in Class C cargo compartments, is ineffective in controlling a lithium metal cell fire. A lithium metal cell explosion can damage cargo liners and activate pressure relief panels. For this reason, lithium metal cells are currently prohibited as bulk cargo shipments on passenger-carrying aircrafts.

Magnetized Material

Loading specifications for magnetized material are described in Subsection 9.3.10 of the DGR. The DGR requires that magnetized material is loaded so that the headings of aircraft compasses are maintained within the tolerances prescribed by the applicable aircraft airworthiness requirements and, where possible, minimize the effects on compasses.

Dry Ice

Refer to the sample Acceptance Checklist for Dry Ice in the back of the DGR manual. This checklist, or a similar version, is required for all dry ice shipments when a Shipper's Declaration for Dangerous Goods is not required. The checklist provides guidance for proper documentation, packaging, marking, and labeling of consignments containing dry ice.

In the event of a release of dry ice during package handling or preparation:

• Do not handle dry ice with bare hands, as this may result in rapid frostbite or injury.
• Ventilate the area where the dry ice has spilled or leaked, and be aware of potentially hazardous concentrations of CO2 gas.

CO2 is heavier than ambient air and will remain in low areas without adequate forced ventilation.
