Where I work, there have been some folks who worked for 5 years in a mega-construction project in Tawain which involved construction of bridges, highways, tunnel, etc.

But just recently I was told, in that project which costed $2 billion dollars to construct....54 people died during the construction....at different times in different locations. Needless to say there is much more lax occupational safety regulations in certain countries, even in a industrialized country like Tawain.

How life is valued..or NOT valued over making of money. Safety for anything requires time to educate users, participants, citizens; buying safety equipment, etc.
