One who is assisting in carrying a wheelchair bound invalid up or down a flight of stairs and while doing so a Siddur or Sefer falls on the floor. Is it correct to leave it lying in disgrace until he finishes dealing with the invalid as otherwise it maybe could be a Sakana (danger) to let go of the wheelchair? What happens if it only looks like danger to others but it really isn’t. Should one also refrain?

Horav Shlomo Miller’s Shlit’a opinion is that the safety of the wheelchair patient trumps over any other mentioned consideration. Since after all, he is assisting in carrying a wheelchair bound invalid up or down a flight of stairs, that and any other even minor concern to the safety of the patient takes precedence.
