On this date in 1965, The Long Beach Independent announced that Haynes Steam Plant would be letting off steam intermittently until January 14th to test a new boiler. The tests were made between 4 p.m. and 9 p.m. on weekdays and between 8 a.m. and 9 p.m. on Saturdays.
Residents were warned that the tests would often be accompanied by a shrill, high-pitched sound, but The Los Angeles Department of Water and Power didn’t want anyone to be alarmed.
Sundays were apparently reserved for residents themselves to let off steam from being forced to listen to boiler tests all week.
