Ok, I’ve tried to come up with answer myself but I cant.
Why do some sites (lafarge springs to mind) not allow you to wear them on site? 
I think it’s because they don’t have any proper ankle support.
It’s because if you have an accident which is trapping your foot they are difficult to get off. If you have lace up boots they can simply cut the laces and release the foot from the boot without causing any further damage. Makes sense if you think about it although I wear slip on boot type (not riggers) and have to change them at some sites for lace up - Celsa for one…pain in the arris for it 
Tis the wondrous Elfin Safety culture we live in now…
Riggers do not provide any ankle support on uneven ground apparently! ie it’s easier to twist/sprain your ankle while wearing riggers than it is with proper lace ups…
Most, if not all of the quarries are the same now…
It isn’t actually the HSE that have a problem with Rigger Boots, it’s the Fashion Police, they’re on the same list as Crocs

I think your right, well so I have been told and it’s now our company policy, they now do an ankle high slip on that is allowed, it has stretchy sides that can be cut easily and the boot removed.
I reckon they ban you cos you look like a jakey bassa 
We have a choice, but they’re not recommended. I can’t drive in them but a lot of injuries have happened in construction and quarrying by machine drivers slipping (muddy boots) and breaking ankles when their feet go through the machine steps.

Nooo i love my riggers, apparently shorts and riggers are not such as good look though 
wouldnt been see dead in Crocs though! 
Some sites that don’t allow riggers because they don’t give adequate ankle support DO allow welly boots! WTF is going on?

I see your point but what sort of rescue crew cant cut a pair of boots off?

We’ve had this come up at our drivers meetings & the argument from both sides (management & drivers) hit a grey area.
Of course the company wants to keep up with HSE legislation & HSE take a dim view on rigger boots although as far as i’m aware they havent banned them from anywhere , it’s down to individual company policy.
The excuses were, no ankle support,hard to get off after an accident , & tarmac , sand & aggrigates falling down in the boot while being worn.
Fortunately we deliver animal feeds on farms & we rarely if ever go onto building sites or quarries so the suggested policy of banning rigger boots got bogged down in personal preference .

Are palce has banned wely booots as well , they say that if a sight is that bad you have to wear wellies, you shouldnt be delivering there.

It’s mainly our own sites that are crap.

To put an ankle or lower calf break/fracture into a splint the boot needs to come off pretty quick. A standard first aid kit will only have scissors/knife to cut laces not a thick leather boot. Depending where you are an ambulance could take quite a while to get to you.
