Convention shall affect the implementation of other instruments concerning sanitary and veterinary control. 7. Nothing in this Convention shall affect the liberty of the Parties to adopt stricter measures for the protection of animals during international transport. Article 5 Authorisation of transporters 1. Each Party shall ensure that transporters transporting animals for commercial purposes are: (a) registered in a manner enabling the competent authority to identify them rapidly in the event of failure to comply with the requirements of this Convention; (b) covered by an authorisation valid for international transport granted by the competent authority of the Party in which the transporters are established. 2. Each Party shall ensure that the authorisation is granted to transporters who entrust the transport of animals only to personnel who have received proper training on the provisions of this Convention. 3. Each Party shall ensure that the abovementioned authorisation may be suspended or withdrawn where the competent authorities that granted the authorisation are informed that the transporter has repeatedly or seriously violated the provisions of this Convention. 4. Where a Party has observed an infringement of this Convention by a transporter registered in another Party to this Convention, the former Party shall communicate details of the infringement observed to the latter. DESIGN AND CONSTRUCTION Article 6 Design and construction 1. Means of transport, containers and their fittings shall be constructed, maintained and operated so as to avoid injury and suffering and to ensure the safety of the animals during transport. 2. The means of transport or container shall be designed and constructed so as to provide animals with adequate space to stand in their natural position, except for poultry other than day-old chicks. 3. The means of transport or container shall be designed and constructed so as to ensure: (a) sufficient clear space above the animals in their natural standing position for effective air circulation; (b) air quality and quantity appropriate to the species transported can be maintained, in particular where animals are carried in a fully enclosed space. 4. Means of transport, containers, fittings, etc., shall be strong enough to contain the animals' weight, to prevent them escaping or falling out, to withstand stress due to movement and, where necessary, to contain partitions to protect animals from the motion of the means of transport. Fittings shall be designed for quick and easy operation. 5. Partitions shall be of rigid construction, strong enough to withstand the weight of animals being pushed against them and designed so that they do not impede air circulation. 6. The means of transport or containers shall be constructed and operated so as to protect animals against inclement weather and adverse changes in weather conditions. In particular, the external roof directly above the animals shall minimise absorption and conduction of solar heat. 7. The floor of the means of transport or container shall be anti-slip. Floors shall be designed, constructed and maintained to avoid discomfort, distress and injury to the animals and minimise leakage of urine and faeces. Materials used for floor construction shall be selected so as to minimise corrosion. 8. The means of transport or container shall be so designed and constructed as to provide access to the animals to allow them to be inspected, and if necessary watered, fed and cared for. 9. When animals need to be tied, appropriate equipment shall be provided in the means of transport. 10. Containers in which animals are transported shall be clearly and visibly marked to indicate the presence of live animals, with a sign indicating the top of the container. 11. Means of transport, containers and their fittings shall be designed and constructed to allow easy cleaning and disinfection. PREPARATION FOR TRANSPORT Article 7 Planning 1. For each journey, the person responsible for the transport of the animals shall be identified so that information on the organisation, carrying out and completion of the transport can be obtained at any time during the journey. 2. Where the intended journey time exceeds eight hours for the transport of domestic solipeds, and domestic animals of the bovine, ovine, caprine and porcine species, the person responsible for the transport shall draw up a document specifying the arrangements established for the journey and in particular the following details: (a) identification of the transporter and means of transport; (b) identification of the consignment and accompanying documents (animal species, number of animals, veterinary certificates); (c) the place and country of departure, places of transfer, places where animals are to be unloaded and rested and the place and country of destination. 3. The person responsible for the transport shall ensure that the intended journey complies with the respective rules of the countries of departure, transit and destination. 4. The person in charge of the welfare of the animals
