Don't know the regs, but once saw an SDS for it that said the vapor was so heavy it would flow out the bottom of a fume hood and roll across the floor.  The SDS recommended using it outdoors and standing upwind. Seriously.

Ni(CO)4 is the basis of the Mond Process for extracting and purifying nickel from ore.  Blow CO over the raw ore, then thermally decompose the Ni(CO)4 around 225 °C to regenerate free CO and deposit nickel. In fact, it can be used to nickel plate items as it leaves a mirror finish.   It reportedly has a musty odor similar to moldy hay.  I always tell my students that Mond managed to write "musty odooo-." in his lab notebook but that's just a little chemistry humor.  That's my homage to a scene in Monty Python and the Holy Grail: https://www.youtube.com/watch?v=ZlIz0q8aWpA 

It's basically insane to use this material for an industrial level process. I would highly discourage its use under any circumstance.

I have a client in California who is considering using a process that uses nickel carbonyl. I have made them aware of the extremely toxic nature of this compound. The only reason they are considering it is that it solves a problem that would be very difficult to achieve any other way. My question to the community is this: what, if any, specific regulations are there regarding the use of this compound?

Thank you
