Okay, well, i've been wondering this too, but the only thing I know about doing this is the fumes that come out of the vent. It is a info_particle_system, with the particle name of: human_cleanser, or human_cleanser_cheap. Here is a list of particles for future reference! https://developer.valvesoftware.com/wiki/List_of_Portal_2_Particles

I'm at work just now, but if you find a map made by myself, Portal Raider Toxic B3, it has exactly what you are looking for. Feel free to decompile the map. I will send u the .vmf if that does not work

Here is the .vmf as promised. Go into the main room, to the left you will see 2 pipes, the neurotxinn is in the pipes. The countdown screen is on the wall at the back, hope this helps.

To kill the player when the timer runs out, you could place a trigger_hurt covering the entire map and activate it once the timer runs out.

or, an easier way is to make a logic_relay and add the output
ontrigger - @command - Command - startneurotoxin/ kill delay: how long you want to wait

and when the player kills the neurotoxin, disable the trigger.

Isn't cancelpending a better option?
That allows it to be activated again in case you do need to add some more neurotoxin in case the test subject needs to hurry up a bit more?

Sometimes when I'm bored, I used the complicated methods of mapping.
