[quote=redkimba]You are not being silly; it's right and good that you worry about your husband.
----------------------------
Just make sure that he's passed all the OSHA medical testing that is vitally necessary for his demanding job. He would not be allowed to work there if he was not able to, but your fears for him are normal. I'd be worried too, but I would also add my own fears of such high places to that and make myself miserable.
Just let him know you love him and you back him in anything he does in his work.
Remember, these jobs have foremen who will keep a sharp eye on all the workers and will force them to do the right thing.
Besides, your DH would not have gotten the job in the first place if he wasn't considered good in his work.
Wishing him and you the best.
