"Routed by ammonia fumes, occupants of the Boatmen's Bank building crowd the corner at Broadway and Olive street. Some 2500 persons were driven from the 19-story building and its 11-story annex by fumes escaping from a break in a refrigerant pipeline beneath the pavement in the 400 block of Locust street Monday."
"Evacuating Boatmen's Bank building are customers of the Boatmen's Coffee Shop (due to leaking ammonia fumes), who hurried from the ground floor annex, using the Locust street entrance of the building."
