Design a storage and transportation system for the safe handling of hydrochloric acid, a hazardous chemical commonly used in the chemical industry. Your system should include all the necessary equipment, materials, and procedures, and should be in compliance with regulatory standards for the storage and transportation of hazardous chemicals. Additionally, address any potential risks or hazards associated with the storage and transportation of the chemical and explain how these risks will be mitigated.
