The regulations are 1.5m depth for excavations, which is a guideline,
insofar that if someone is kneeling in a1.5m trench they are gonna get
buried if a side collapses.
Yes I do get into deep holes but test the sides first to determine that
they are stable and dry, if in any doubt I'll bench it.

I have some very good cast iron jackstands which I use regularly. I do not
care to be a greasy spot under my car. They are used when I need to remove a
wheel. Just used a couple of pairs the other day win I was putting new pads
and rotors on the wife's 2005 Mazda 6.
Nothing dodgy about these ramps - they are solid wood and could easily support
far more weight than this car. I built them because I had a pair of the
stamped steel ramps a while back, and I had two major issues with them:
1.) They wouldn't stay put so you could drive up on them. That is, when the tire came up
against the ramp the ramp just skidded forward. The manufacturer's suggestion: Put them
on a "soft" surface, or place a piece of rubber sheet under them so they
wouldn't slide on the floor.
2.) One of them started to bend or distort and dropped in height by about an
inch. It was not overloaded according to the ratings and the car I had on it
at the time (a 1970 250C) was well below the maximum load.
That's when I got rid of them.
The jack has a very slight leak that's been present for some years. The lack
of hydraulic fluid was a cumulative thing that I had just never addressed. I
haven't seen any leakage since I refilled it, so I'll continue to use it with
diligence. That means inspecting it before each use.
Again, I am very careful when working under a car and usually have multiple
means of supporting it in place. I have no intention of being squished under
my car.
When you're excavating a trench, do you ever get down in it without shoring?
I'll bet not. My rule - never get in a trench or hole deeper than my waist.

Dunno, dodgy ramps and a flakey jack, sounds a bit dodgy.
I have a pair of metal ramps but gave up using them ages ago, I might drag em
out now and again but the car is jacked up and the ramps put under the tires. I
just hate driving vehicles up ramps.
Over the years I have invested in jack stands and now have three pairs, ranging
from weak to very strong, this is particularly useful as a lot of jobs involve
removing the wheels, hard to do when the wheel is sitting on a ramp.
Where is this jack losing oil? A jack that has issues is to be treated with
great care.
