You can name all the safety certificates you want (which I am all aware off).
A very respected, smart and highly intelligent person in science and engineering with over 50 years of experience, ones told me the following (unfortunately I'm not allowed to share his name in public)
"People always say safety first. Which is very incorrect and even dangerous.
It is thinking first (just follow basic science and engineering), than safety and third is sometimes just random bad luck"
In fact, it is even proven that blindly following safety protocols can even lead to potentially more dangerous situations.
You should teach people the how and why instead.
With me a lot of people in the field are getting extremely sick of all the ridiculous so called 'safety rules'.
You can write pages about how many years of experience you have and what kind of qualifications or certificates etc, but it all simply comes down to some general science knowledge.
Because it simply doesn't make sense why nobody cares about batteries, while it doesn't cost much to kill someone very easily with a 9V battery!
I know companies/countries where someone isn't even allowed to handle a bloody standard knife anymore
If people are to dumb to know what they are doing, they shouldn't be doing it in the first place.
In fact, in a lot of countries that's even how the law system work.
Which means that it's not important anymore if a product was 'unsafe', just by the fact that you were doing things you weren't qualified for cancels everything out.
Btw, with all the respect, but I don't know who brainwashed people that 'you need approved safety facilities' to test safety.
Than you simply have fallen in the big marketing trap.
You forget the reason WHY these facilities exist, with the one and only reason: cover themselves in court.
Nothing more, nothing less. That doesn't mean that other ways aren't safe.
(in fact I know many so called 'safety regulations' in some countries that are absolutely forbidden in others)
Second to that, if safety is so important, why is it SO difficult and SO expensive to get these tests done, of to even get the basic documents?
These things should be open to the public.
All of this doesn't mean that there are people out there that make these type of meters, review a lot of meters or just have a very good understanding what potential dangerous there are and how to tackle them or are just smart people with enough knowledge/resources to find that out.
These meters and safety tests are not done by unknown hyper smart aliens.
So in fact, I would
ENCOURAGE people to dig into this and share it to the public because in my opinion that's even your responsibility as an engineer/scientist.
And to add something extra for the people who have so "many experience in the field", maybe it would be better to help people out, explain it how it is done properly instead of kicking people shins.
If you can make the time and energy to rant, you can also use the same time and energy to be productive instead.
Talking about proving.......
