Brendan McBride was found suspended in the metal hatch of a clothes bank belonging to Save The Mothers Trust. His family believe he had been trying to clamber inside to find somewhere to sleep.
The inquest was told that Mr McBride was thought to have been standing on a plastic container so that he could reach into the bin when he slipped, getting his arm trapped and leaving him suspended.
The 19-year-old was found by a passer-by on his way to work on May 23, but he was pronounced dead at the scene.
The inquest into his death was opened on Tuesday and it heard how the hatch at the charity bin in Great Horton, Bradford, had caused the teenager a significant arm injury resulting in a significant amount of blood loss.
Assistant Bradford coroner Dr Dominic Bell was told that Mr McBride was known to have been drinking the night before he was found and had told his mother Paula Denison he was going to visit friends. She told him to be back by 9.30pm but he never returned.
