Abstract

Stepladders are used during professional and domestic activities. They have a rectangular base; the rungs are parallel to the short base side. When the stepladder is placed with the long base parallel to a wall and near this wall, the user is close to the wall: it is easier for working. Then the user could exert a force perpendicular to the wall thus parallel to the short base and the stepladder is very unstable. The force producing that instability is small compared to the maximum push force exerted by a human, as low as 60% of the maximum for a strong man. Even if the user is cautious, he could easily overturn a stepladder. The potential for accidents is the result of a conflict between the ease of work and a low overturning force. Therefore fall accidents with a stepladder are still numerous.
