Insulating exterior of old cast iron boiler?

I have an old cast iron boiler (steam system). The boiler is covered with asbestos or plaster on the outside. But the boiler throws off a LOT of heat thru the insulation. And also some of the asbestos or whatever has come loose. A few pieces have fallen off.

Can I maybe add some type of insulation to the outside of the boiler, or is that a bad thing to do for some reason?

Boiler Insulation

If you allow the boiler to cool, you can wet the asbestos & remove it yourself if you use the proper precautions to prevent the fibers from becoming airbourne. After the asbestos is off you can wrap the boiler in foil faced fiberglass insulation or with Stic-Tite insulating cement you mix with water & trowel on.
