Did you know that every merlin park has it's own on-site H&S team? And that when you say they would be in trouble, they would only be in trouble with themselves unless whoever was involved took it further which usually they don't as Merlin (a very big corporation) would just pay them off to keep quite.
So in essence you don't know what you are talking about when it comes to H&S. Merlin Entertainments as a company have a HQ H&S team which work with separate parks H&S team which spend every minute of every day reviewing situations and possible outcomes of circumstances. When they feel something is unsafe they remove it long before it happens. Take Stealth queue-line last year, someone reported that part of the fencing had collapsed and by the next morning hey presto the queue had been fixed.
I'm not sure if you know this but, accidents are Merlin Theme Parks are EXCEEDINGLY rare, the rate of which I believe is even lower than Disney.
To sum up the above, H&S are always investigating and when they think something could happen they stop it before it does.
