Skydrol LD-4, 500B-4, Chevron Hy-jet 4.
As stated, when you get a hyd leak it often is from a pinhole in a hose, pipe, seal, then a mist forms. Not very pleasent for the Lungs, causes you to Cough and Choke, Eye Irritation, and Irritation of Sensetive Body Parts.
Have been involed with problems where the liquid has been heated by the aircraft braking systems, Breaking down the hydralic fluid into an acid, the residue entering the system and causing system failures.
Another thing to think about, but maybe not so for F1, is this liquid tends to break down plastic based structure and components, if allowed to be in contact for any length of time.
