Final answer:
The correct answer is 'd. Industrial hygiene', as it refers to the control of environmental factors that may lead to workplace sickness or discomfort, and is not a direct cause of accidents on the job.
Step-by-step explanation:
The option that is NOT a leading cause of accidents on the job is d. Industrial hygiene. The leading causes of workplace accidents typically include management failures, human error, and unsafe behavior. Management failures might involve inadequate training or poor safety policies. Human error can be attributed to mistakes made by workers, often because they are fatigued or not properly trained. Unsafe behavior encompasses actions by workers that violate safety protocols. On the other hand, industrial hygiene focuses on recognizing, evaluating, and controlling environmental factors or stresses in the workplace that may cause sickness, impaired health, or significant discomfort among workers. Industrial hygienists use environmental monitoring and analytical methods to detect the extent of worker exposure and employ engineering, work practice controls, and other methods to control potential health hazards.
