On Feb. 17, 1949, chlorine gas sickened 17 people - including several firefighters - at the Young Men's and Young Women's Hebrew Association building in Paterson.
"Police said a pipe connection came loose while workmen were removing the chlorination system, used to purify water in the swimming pool," The New York Times reported.
An injured firefighter, Milton Katz of Engine Co. 5, was placed in an oxygen tent at St. Joseph's Hospital, the newspaper said.
