Which of the following is NOT one of the major causes of work injuries?

The correct choice highlights that incorrect training is not typically classified as a major cause of work injuries in the context of the other options presented. Major causes of work injuries usually involve physical hazards that can lead to immediate bodily harm or accidents, such as burns, slips and falls, and back injuries.

Burns can occur due to exposure to heat, flames, or chemicals, leading to significant damage to skin and tissues. Slips and falls are common due to wet or uneven surfaces, often resulting in fractures or other serious injuries. Back injuries frequently arise from improper lifting techniques, repetitive strain, or accidents, causing discomfort and sometimes long-term disability.

Incorrect training, while it may lead to situations where accidents can occur, is seen more as an underlying issue rather than a direct cause of injury. Adequate training can mitigate and prevent injuries caused by the physical hazards listed. Thus, while it is a contributing factor to the risk of injury, it doesn't directly fit into the same category of immediate causes present in the other options.
