There is no problem at 200 ppm. Skill issue

  You're saying that as long as it proceeds as expected, then all will be ok. In the worst case (eg, at the 2,000ppm you indicate as an upper range, or after some mis-step in the process), what ppm chlorine gas would be created, and what would happen if you got a noseful of that at close quarters? This is just terrible advice.
