Manually moving loads on even a flat surface can be an arduous task at the best of times, but factor in the additional effort to complete this task up or down a flight of stairs and the task can become extremely physical not to mention having a far greater risk of injury. Narrow stairways, twisting stairs and small landings can all present dangers. The risk extends from the individual carrying out the task itself, through to injury of dropping goods on people using the stairs below and of course to the accidental damage to the goods in question.
