“A total evacuation of staff has occurred, and we are waiting for the arrival of the team dealing with hazardous materials,” a later tweet said, sharing a picture of the scene, with Civil Defence and ROP vehicles on standby.

An hour later, a team in orange suits and head masks from Civil Defence vehicles arrived to contain the leak.

Just past 7:30 in the evening, PACDA tweeted the successful containment of the chlorine leak. (LINK)
