Industrial manslaughter laws are a fine incentive to correctly manage the risks of CO₂ asphyxiation, because it is immediately apparent when your worker has been asphyxiated and the proximal cause is readily determined.

Silicosis takes years to appear so the proximal link is too weak for post facto punishment to have much deterrent effect. It is much more like asbestos in this way, which can also be safely handled but has also been banned.
