As far as health and safety issues go in the UK, Each employee of a company is responsible for any H&S related issues and risk assessment of a situation.
This approach helps to look after others wellbeing and also look after the company should any accidents arise that could have been avoided with the vigilance of the employee.
However, Most company managers etc tend to turn a blind eye and show contempt towards employees that try to work with H&S legistlation that costs the company money.
This attitude makes it hard for anyone to adhere to H&S issues without being labled a trouble maker or someone that is not part of a team thus putting their jobs at risk should they push H&S related issues that the Management don't like.
Management love "YES" Men!
when an accident does arise, then they play the blame game and tend to look at the lower end of the ladder to place the blame.
100% of H&S is down to common sense and logic, If employees don't have either then it boggles the mind why they are employed in the first place.
