While I was just a teen, my uncle was a navy machinist / diesel mechanic / made stuff work after his retirement from the Navy he worked for a heavy equipment company that needed work done on a dump truck, this was moonlight work in our driveway, he had the driver of the truck with him to help with what ever needed servicing.
They had the trucks dump body lifted to perform what needed doing, there was no safety blocking to minimize risks, I don't think it was service on the hydraulic lifting system itself, but out of the blue a critical line failed and the driver was crushed to death, that was a horrible day for my uncle!
Having learned from that lesson, I totally respect the power and vulnerability of any type of lift, be it mechanical screw & lever, hydraulic or air!! I've had old hydraulic floor jacks with weak seals bleed down fast, wasn't worth servicing left for the junk man to take away once I bought a capable replacement.
Respect your tools and understand the safety rules when performing any service.
