Yes I think CH's list is a good starting point, with Steve's bump cap substituting the hard hat.
For the safety glasses, I prefer these, they can be used with or without the elastic strap:
Also with the long sleeve shirt and trousers, I was going to start looking for more durable/protective layers that could (?) offer greater protection against possible cuts and puncture wounds ie: when gaining entry to buildings; walking through hedges and even crossing barbed wire fences etc. I was thinking possibly about the slash proof hoodies and some kind of durable snag proof trousers.
Also what about trousers that take knee pads?
And what about the use of shin pads again to give extra protection to the legs under your trousers.
Gloves are I feel very important, but also vary widely in their suitability, I've yet to find any that I'm comfortable with if anyone has any specific suggestions....
