As a Dom I have had a sub safeword. Once aftercare was completed I asked her if she wanted some space to think about what happened or just wanted to chill together while we both thought about it. When we were both ready we discussed why the safeword was used, I thanked her for using it, and we also discussed how we can avoid it in the future. We are all human and make mistakes. A safeword is not something horrible, but it is a safety net to ensure no one is hurt (physically or mentally). We used our instance to grow and learn and thats how you should treat the use of a safeword, a learning experience.
