Is sending transaction hash safe?

Hello there, I'm curious about something related to cryptocurrency transactions. I've heard that sharing transaction hashes can sometimes be a bit risky. So, I'm wondering, is sending transaction hash safe? I mean, does it expose any sensitive information that could potentially put my funds at risk? And if it's not entirely safe, what precautions should I take to ensure the security of my transactions? I'd appreciate any insights you can provide on this matter.
