A stepladder is a portable ladder that is made of two sloping parts that are hinged together at the top so that it will stand up on its own. 四脚活梯
Onlyoneperson shall be allowed on a ladder at a time except for stepladders that are equipped with steps on both sides. (Rungs are not considered steps.)
But rather than condemn their litigation--which just might be making stepladders and lawn mowers slightly safer--I would criticize lawyers for something else entirely, and that is their writing ability. (It's a fair assumption that lawyers are drafting those encyclopedic hazard warnings.) I propose that consumer product companies fire the lawyers who write safety warnings.
