Although data plates can vary in their appearance, they will all have the same basic information on them. As an operator it is very important to understand all of the information that appears on the data plate. OSHA requires all nameplates and markings to be in place and maintained in a legible condition. 1910.178(a)(6). Modifications and additions which affect the capacity of a forklift should not be performed without the manufacturer’s prior approval. 1910.178(a)(4). And, if any such modifications and/or additions are performed, the data plate, tags and/or decals shall be changed accordingly. 1910.178(a)(4).
