I think the United Kingdom has the highest safety standards. What do you think?

Yes Mohammed I do think that United kingdom has the highest safety standards not because this is where NEBOSH (National Examination Board in Occupational Safety and Health UK) And IOSH (Institution Of Occupational Safety and health) is based but dividing in different types of industry I see in UK safety is practised/considered everywhere.
Consider aviation,Australia AND US has strictest regulations good safety standards too.
Sill you can see like most of the developed countries they do have effective safety standards and control measures in place...

That is true. I agree with you guys100%
