Hi Waseem

Your first post here so welcome to the Forums.

Not entirely sure what you are trying to achieve with your post and you don't indicate what geography you are based in - which would perhaps help set a benchmark as to your expectations.

Yes, of course, health, safety and welfare standards on construction sites in "developing" countries such as, you mention Pakistan, are probably less than satisfactory but that is also the case in the UK and other "developed" nations, such that e.g. fatal accident rates in the US are MUCH higher than in the UK and most of Europe. 

Whilst IOSH has members across the World I doubt that it has many in some "developing" countries such as Pakistan.

To an extent the health and safety standards in many "developing" countries can be expected to broadly correlate with the level of "development" - as less reliance is on cheap manual labour, then health and safety standards should improve as well.

Which then leads to considerations as to how important occupational health and safety standards are in the context of the environment around the workplace. If the chances of a worker dying prematurely (or being severely harmed) are much higher due to the lack of e.g. clean water and good sanitation, then perhaps more focus should be given to improving public heatlh than workplace H&S standards.

So perhaps the need is for overall improvemetn in developing countries, aligned with ensuring that investment is directed to the improvement of conditions for ALL, rather than the few who are often the primary beneficiaries, such that the gap between rich and poor becomes ever greater (just as is happening in the "developed" nations). 

Just to mirror AK if you look at the UN Globally Harmonised System this requires individual nations to adopt in to their own legsilation a UN publication. The UN GHS is neither "Global" (not every country has adopted the system) nor is it "harmonised" with different countries following one of the many published versions to suit their domestic circumstances.

You then have the politicians reversing rival parties undertakings such as Donald Trump withdrawing from the Paris Climate Change agreement.

What is culturally acceptable in one nation may also be prohibited in another for example the use of bamboo as a scaffold material - if we were to write a standard for scaffolds how many years would the technical debate rage?
