Virtual Reality Toxins

Aren't busted canisters explody enough

They will mess you up if you're in the same room as them (mostly because you're now stunned in a sea of hellfire), but they won't spread to other departments.
Even the most catastrophic toxins failure with the exception of a bomb actually detonating will only barely have an effect on research at large, with most of the damage concentrated in the RD's office and possibly artlab due to convection.

This assumes there's no structural failures between toxins and the remainder of research, mind.
