Boiler Room 5 was the second boiler room, between Boiler Room 6 and Boiler Room 4. BR5 was powered up by 5 boilers. The boilers generated steam for the reciprocating engines. These boilers were connected to the 1st funnel.
On April 15th, 1912; this boiler room became the frontline to stop the water from continuing to pour into the Titanic. At 12:45 AM, the bulkhead between Boiler Rooms 5 and 6 gave way. Two engineers, Herbert Harvey and Jonathan Shepherd (who had just broken his left leg after falling into a manhole minutes earlier), died in boiler room 5 when the boiler room flooded. According to Frederick Barrett, who barely escaped the boiler room said that they were swept away by "a wave of green foam".
