Invictus I disagree.

The difference is, IMO, the contractor has a safety consultant and the Boss of the computer company does not.

If I was their advisor I would introduce a similar policy and recommend it is followed.

If he refuses to accept it I would not stay as his adviser.

You interpreted my post incorrectly, I would not threaten to walk away, I would walk away.

I do not work for anyone who does not take my advice, whether from a legal standpoint or not.

I have done it before and may do it again.

A couple of relevant articles on the BBC site from today relating to vaping and people's differing attitudes towards them:

Stonecold, I am self employed and not desperate for work, I find it much better for me not to have to argue with clients who do not see the sense in good safety practices, and I don't get frustrated by working with people who do not really want me to advise but just to use my name as safety adviser.

If everyone acted like myself clients and employers would either be very safety conscious or not have any safety advisers.

It works for me.

Although I readily admit I have no experience of using these devices, and therefore stand to be corrected, I understand that they tend to use glycol as a carrier solvent, so users presumably are at no risk of freezing up on a cold day. I also understand that there is some research that suggests that they are not the safe alternative to smoking we were given to understand.
