When other forms of transport are inappropriate
Whilst carriage by other forms of transport may be possible, States should evaluate a risk analysis which should include consideration of:
- Length of journey. Transport by other forms may result in an unrealistic journey time and could affect the viability of the dangerous goods.
- Infrastructure. The availability of other forms of transport may be limited.
- Security. The comprehensive security provisions of the air mode may reduce the possibility of unlavful interference (theft, etc.).
- Routing. Transport by air may result in a reduced risk of exposure of the public to the dangerous goods in the event of an incident or accident. The risk of piracy may also be significantly reduced.
- Cost. The cost of carriage by other forms of transport may be economically unreasonable. However, the decision to grant an exemption should not be based on cost alone.
