Final answer:
Detonating cord and boosters must be stored in a secure magazine that is specially designed for explosives, located at a safe distance from other structures, and has controlled access.
Step-by-step explanation:
Detonating cord and boosters should be stored in accordance with local and national regulations which often require keeping them in a magazine designed for the storage of explosives. Such magazines should be located a safe distance away from inhabited buildings, railways, or highways and need to be constructed in a way that protects the contents from unauthorized access, fire, and accidental detonation. Furthermore, the environment within the storage facility should be kept dry and well-ventilated to prevent deterioration of the explosives. It is also important to ensure that storage areas are marked with appropriate signage and have strict access controls to ensure safety.
