Betting this was just under 10 pounds. 
Thatâs a RQ joke as the RQ for Cl2 is 10 pounds – CLEARLY we have exceeded that in this event. (But you never know!)
All jokes aside, this is a big one. People wanting to know why itâs taking so long to get an âall clearâ 2-hrs after the leak was isolated just donât know Chlorine! At 3Xâs heavier than air, itâs a LAZY chemical – just wants to sit down and hang out. With an IDLH of 10 ppm and a PEL/TLV of 1.0 and 0.5 ppm, respectively, it will take some time (even with mechanical forced air ventilation) to dissipate the cloud to safe levels.
Not that I want to be there, but this gets me excited. FYI, I loved my ER apparatuses and no way in H_LL I would have my nice rig sitting that close to an uncontrolled cloud of Cl2. Just me though, everyone must have a different 2024 ERG booklet than mine!!
COMMUNITY AWARENESS & EMERGENCY RESPONSE (CAER) sirens were activated around 9 a.m. after an active chlorine gas release at a chlorine manufacturing facility. At least four persons have been treated, but their conditions were not disclosed.
The local Police Department confirmed that there was an active Level 3 (Highest Level) chlorine release, meaning the gas had reached off-site.
At 9:46 a.m., CAER reported that the leak had been stopped; the shelter-in-place order was lifted by 10:40 a.m.
