The question about safe to drive is up in the air until you have a better clue of the leak size and the location.

Start by refilling the system with distilled water. Wash with soapy water the entire area where the leak sprayed and let it dry. Why? There is so much coolant in the pictures that it will be hard to tell where new coolant is leaking. Coolant doesn’t really dry for weeks on it’s own, so the soapy water gives you a clean baseline.

I use paper towels a lot for leak detection. Zip tie towels, or small sections of towel anywhere you suspect a leak. Don’t let them touch or they will wick. And water doesn’t run uphill but it does run downhill, meaning the highest point you see a leak is closest to the origin.

Have you looked at the outside of the radiator where the tubes join the header for any signs of coolant. Keeping in mind that the fan pulls inward and will spray any coolant all over the place in the pictures you attached.
