What safety precautions should I follow when loading the dishwasher?

Load sharp knives with the handles up to reduce the risk of cut-type injuries, and position sharp items so they are not likely to damage the door seal. Do not wash plastic items unless they are marked 'dishwasher safe,' and do not touch the heating element during or immediately after use. Children should not be allowed to play in or on the dishwasher, and you should not sit on or stand on the door, lid, or dish racks. (Page 2)
