When I was the night operator for the county water & sewer district, I handled Cl all the time- it's nasty stuff.
One of the original WWI poison gases, it's always proved a two-edged sword when tried as a weapon- as likely to harm your guys as the enemy.
It is very deadly if the victim inhales a concentrated dose, but the problem has always been delivery of the stuff. And, being a gas, it dissapates fairly rapidly. That said, in an enclosed space, it's bad stuff.
I wouldn't be terribly worried about it, but it would be nice it they could account for it.

I recall all sorts of precautions in my chem labs decades ago. How hard would it be to fill a milk jug with it and would the plastic cap need more than tape to seal it?
Thanks backhoe for that feedback.
