IV Ni(CO)4 is highly hazardous, much more so than implied by its CO content, reflecting the effects of the nickel if it was released in the body. [1] Historically, laboratories that used Ni(CO)4 would keep a canary in the lab as an indicator of nickel carbonyl toxicity, due to the higher sensitivity of birds to this toxin.
