Well maybe start with making a glass cylinder with a 1mm sq area whole through it's middle.
And then fill it with mercury (after stopping one end of course).
we have no rights these days, things such as rights have become a pseudo fact.
I have this image in mind of your bus having a pc installed which automates it. Sue sits there with her feet up reading the news paper and her sensors and servos do the rest... proper little Queen of Sheba. Ah that's the life... No wonder she's always smiling. Just when the law comes into it, makes her stern faced.
Getting very OT, I'm afraid. But it is related to first aid in the workplace - which may affect quite a few electrical engineers, in theory only (hopefully).
Well, the rule was introduced after they had tried (and failed) to discipline me for leaving the bus to give emergency aid earlier in the year - and my refusal to agree not to do so in the future. We are/were trained to the "Appointed Person" level (about the lowest level of first aid certification there is) and are supposed to render first aid until someone better-trained is available.
However, they said that was only "in the workplace" (i.e. the bus) and only applied to giving aid to employees and fare-paying passengers. Presumably, if someone did have a heart attack on the bus, my first check should have been of his ticket ;)
The engineering work-place analogy seems to be, an "Appointed Person" could and should help a fellow employee at work who, say, electrocuted himself. But he shouldn't step out of the building onto the street to give the help to a pedestrian walking by, electrocuted by a faulty street light. Your company could become liable, apparently.
I don't know what the position is "across the pond" - I get the impression that your society is even more litigatious and wonder what your rules for rendering first aid in or near the workplace are..
Here, in the UK, an increasing number of activities are being curtailed because of the threat of litigation, including Village Fetes, "conkers", selling home-made cakes by Women's Institute, selling second-hand electrical equipment from charity shops, etc. A Chartered Electrical Engineer is no longer "qualified" to safety-test a mains radio..
yep everybody wants to sue somebody it seems... and every one has heard about the hot chocolate at the drive-in case, however it is my understanding that many many silly lawsuits are rejected by level headed judges: "you bought a hot beverage, spilled on yourself, and now you want to sue someone? get out of my court and pay the court costs too!" its just that when the system works the way it should it isn't newsworthy so news coverage of the oddball cases make it seem like everything is out of proportion.
and likewise insurance costs are restricting activities like concerts, fireworks, and many other public events.
i was amazed to discover that the UK requires a license to have a TV set. can you tell me the justification behind such a law?
if an EE is not allowed to test electronics.... who is? a PHD? or is it only left handed descendants of Tesla?
