How do you remove glass from body and hair without hurting the person?

If it were at my house, I would have him lean over the side of the tub and use the shower head on a hose to wash it out - diluting hair shampoo or dishwashing detergent liquid to be able to pour a soapy mixture to remove grease/oil on the hair and then comb the hair from the back of the neck forward to get glass without hands touching it. Otherwise, I would probably do the same thing in the backyard with a hose.

well depending on the size of the glass, you could use tweezers or a plier. Just look for the peices, and take them out. try washing out his hair. use gloves, so you don't get scratched. You should also go to a clinic, maybe, to make sure all the peices are out so he does't get infected! And sorry to say, but it will be uncomfortable for him. there's no way of removing glass, without slight discomfort.

Lastly, does his boss know of this accident? I don't think it's right to send someone home full of glass...!

Good luck :)
