How many design classifications are industrial trucks classified by, regarding power type and hazard degree?

Industrial trucks are classified based on power type and hazard degree into a total of eleven design classifications. This classification system, outlined by the National Fire Protection Association (NFPA) and other safety organizations, helps in determining the appropriate use of industrial trucks in various environments, particularly in relation to fire hazards and the type of fuel used for power.

By dividing industrial trucks into these eleven classifications, safety professionals can ensure that the right equipment is used in the right context, minimizing risks and enhancing workplace safety. Each classification reflects specific operational characteristics and safety concerns that need to be addressed when using that type of equipment.

In contrast, the other numbers mentioned reflect an incorrect understanding of the classification system and do not align with those recognized standards for classifying industrial trucks.
