There was no fireman called Smith. Maybe you mean Ernest George Smith, who worked in the boiler rooms as a trimmer. We know that he died, but of his life very little is known other than the usual details recorded when signing on - ie his name and address, age (26) and county of birth (Hampshire). He was signed on for the 8-12 watch, so he would have been working at the time of the collision with the ice.
Susan - Perhaps the following from my database might help?
Smith, Ernest George. Lived at 1 St Marys Buildings, St Marys, Southampton. Occupation - Trimmer. 26 years old. (Born in Hampshire).
In memoriam, The Hampshire Independent, Saturday, April 17, 1915:

A correction to what Brian posted: "Mansion House Titanic Relief Fund Booklet, March 1913) Number 620. Smith, Alice Jane. Class G dependent." does not relate to Ernest George Smith, trimmer. Ernest Smith does not feature in that booklet. - Case No 620 was J Smith, Assistant Baker.
