IMHO. Even with a Padlocked OFF cct there can always be the risk of a leakage from other equipment ie. Capacitors discharging & if in a bank of Caps could be a powerful enough boot to cause harm.
Has happened, & if someone was up a ladder, could cause a physical reaction to drop you off said ladder.
On an unlocked but OFF circuit there is always the chance some clown comes along & sees it is off & switches it back on regardless of any warning labels & signs.
The tools are easier to grip.
That's the problem - almost everyone walking around infected with CV19 isn't sick yet and doesn't know it, so they should be wearing masks - I'm hopeful that compliance will be high and enforcement strong with this - it could mean we could get back where we were a month ago quite quickly - as always though it will depend on what the selfish and low IQ parts of society do now - after all, they are the ones that caused the issues here in Melbourne we are seeing now.

How would I know I was ill if I didn't have symptoms and hadn't been tested? Even people who do develop symptoms can go several days before the symptoms appear so they may not be aware they are infected. Why take the risk?
If I was in Melbourne I'd be happy to wear a mask. Also in close conditions anywhere such as a bus, train or small space. Why not?
Really, this just confirms my previous opinion that it would be a big help if all, or at least most, people would get tested, preferably in the same week.
Lets have a National Testing Week and get the job done. There are ample test kits and they have to be used within six months or thrown out, so let's do it.
Its frustrating sitting around waiting to see if we get sick, let's get on the front foot and do something to eradicate the virus.
The more that get tested the more positives will be found and the more community transmission can be stopped. It just seems like a no-brainer to me. I've been tested twice and I'm very happy to get tested as often as seems necessary.
Got my mask in my pocket ready to go, and I'm not even in Victoria. Its not reusable, but I'll get a reusable one in time.

Problem is that testing people with no symptoms almost always shows a negative result - even if in fact they do have it. Compulsory mask wearing and staying at home is about the best way to slow it - we just need people to actually do this - there are still way too many people out and about for no good reason.
I went out this morning to the Docs, then past the Supermarket - and that should be it now until at least next week, but down the street was as busy as any normal weekday from what I saw - all the shops were open and there were people wandering in and out of them as per normal - not sure what part of essential that is...

Its certainly true it can take a few days for the levels to get up high enough to give a positive result. But at least more positives would be identified.

						Super ModeratorNot rhetorical, and (likely unintentionally) a good pair of questions.
Masks serve several purposes. Social distancing is designed to avoid direct aerosol contamination with the theory that a virus laden aerosol will fall prior to it hitting the next person. Masks are designed to prevent the aerosol leaving the mask. That has the double whammy of significantly reducing the immediate person to person transmission, but also preventing the virus landing on surfaces leading to contact transmission.
In theory if masks work there is no need for social distancing. The problems are several. People are using masks (or scarves or tea towels or whatever) which significantly reduce the emission of aerosols but don't completely stop them. Then we have people using inappropriate masks (like N95s with exhaust valves). Then we have people using the right masks, but improperly fitted (like the plonker I saw in the lift last week who had 6 surgical masks on with a gap either side so big I reckon I could fit a ping pong ball in there).
So the concept (as has been stated many times in this thread) is the mask protects you from me, but nothing is perfect. It's a bit like the effectiveness of a condom is directly related to precisely the user follows the instructions. Even then, they're not 100%. Social distancing just adds extra precaution to the equation to reduce the probability of contamination and also prevents accidental person to person contact and that extra transmission vector.
