I work for a maintenance dept and we have a forklift basket, is it legal to use?

If they are legal what are the restrictions?

Heres the deal, my boss wants to rent a 40 ft boom forklift and have me use the basket to change out some pole lights.

I am not in favor of this, I just have a bad feeling about getting in there with no controls 40 feet up.

I am aware of fall protection and I always wear it on a boom man lift.

My boss is not a tradesman he is a manager type and he probably saw the forklift basket and figured it would be ok.

If anyone can point me to some sort of OSHA regulation or something it would be most helpful.

Many thanks.
