While the exact details of the pump malfunction were not disclosed, accidental chlorine gas emissions are common when there is no electrical interlock between the chemical feed system and the pump. The pool pump may stop while the chemical feed equipment continues to add chlorinebased disinfectant and acid into the line, that react to form chlorine gas. When the pump re-starts, this gas is released into the pool area endangering any swimmers or those nearby.
