What must be done after packing a parachute for emergency use?

After packing a parachute for emergency use, it is essential to ensure that it is sealed securely. This step is crucial because a well-sealed parachute prevents contaminants, such as dust and moisture, from entering the container, which could compromise the parachute's deployment and functionality when needed. A secure seal helps maintain the integrity of the packed parachute and ensures that it remains in optimal condition during storage.

While inspection by a second rigger is an important safety practice to confirm that the parachute has been packed correctly, it is not the immediate step that follows packing. Color-coding might be beneficial for identification but is not a standard procedure immediately after packing. Re-packing for usability is also not a required action right after packing; rather, parachutes are typically packed for emergencies and should remain in that state until needed or regularly inspected as per maintenance protocols.
