Which of the following is not an indirect cause of stacker disasters?

Safety audits play a crucial role in identifying potential hazards and ensuring compliance with safety regulations in workplace environments, including those involving stacker operations. They are proactive measures aimed at preventing accidents by assessing risks and implementing appropriate controls. In contrast, the other options represent factors that can lead to stacker disasters.

For instance, a lack of safety and health education and training for operators can create a situation where individuals are not equipped with the necessary knowledge to operate equipment safely. This gap in training can lead to mistakes that increase the risk of accidents. Similarly, poor maintenance practices can result in equipment malfunctions, which could directly cause accidents if a stacker were to fail while in use. Improper loading techniques can lead to instability, causing loads to shift or fall, which is a direct risk factor in stacker operations.

Overall, safety audits are designed to enhance safety measures, whereas the other factors contribute to increased risks, emphasizing the critical role that effective safety practices play in preventing stacker disasters.
