Safety requirements-not tips-when using floor jacks and jack stands | Hagerty Media
After a ratchet-and-socket set, box-end wrenches, and screwdrivers, the most commonly used automotive DIY tools are probably a floor jack and a set of jack stands. Whether you're changing a flat tire, replacing brake pads and rotors, or performing work under the vehicle that requires it to be raised for clearance or comfort, it's important to understand that the functions of floor jack and jack stands are tightly intertwined. https://www.hagerty.com/media/opinion/the-hack-mechanic/safety-requirements-not-tips-when-using-floo...
Thanks for writing this; this is the kind of stuff I obsess over when working on the car. Most of the time I'm just inspecting the brakes and suspension before and after track days. For extra safety I put the wheels under the frame rails as soon as they are off the car.
That's a great question, especially since, due to operator error on my part, I once did have the mid-rise lift depressurize. I don't use jackstands--they're not tall enough--but if I'm working under it for extended periods, I'll put a wheel and tire under it as a last-ditch fail-safe.
