Where a hut is located is critical to the calculations really - the TSG is in the middle of a busy honeypot village whereas Red Rose (for example) is literally in the middle of nowhere, so it's hard to compare them directly. But both sets of locals may or may not want activity yet if it means random visitors arriving from different parts of the country. The population of Castleton can't be ignored in our determinations as we operate alongside them. We have a few couples in the club who live together, so they could share a bunk and use a combined shower/toilet together or separately. But no-one else could, if they were to choose to do that, until it was all cleaned down again afterwards. As our showers are normally used after caving, they get muddy, so often get hosed-down first and then cleaned with disinfectant on the contact surfaces. But if the hosing-down blasts virus all over the changing area (as the water spray always does), then that's hardly the answer. So someone has to hand-clean everything, and who's going to do that as a volunteer? You might catch Covid-19 from cleaning down someone else's showering?
We're not panicking over the legal aspect per se, but as volunteers we do have to be aware that we're facilitating a hobby primarily, and that our normal risk-assessments are tilted more toward caving activities and keeping the physical structure of the building safe rather than the implications of delivering a potentially fatal infection to our members and visitors, outside the obvious ones from water pipes, etc. So there's a lot more thought needs to be put into how we implement any new procedures, and what impact they might have on 'normal' hostings, both for us and our neighbours. The local villagers are famously tolerant of late-night (sometimes noisy) revelry at The Chapel, possibly as many will have consumed similar beverages and 'understand'. And I suspect some like our eccentricities and believe we make the place more interesting. But I doubt they would understand that sort of activity right now, so I would imagine that any re-opening for us would have to be very slow and steady, and extremely well-behaved.
