Which of the following is NOT a category of hazards?

The correct answer is financial because it is not traditionally categorized as a hazard in safety practices related to health and environmental risks. Hazards typically fall into categories that directly impact physical safety and health in workplaces or labs.

Chemical hazards refer to any harmful substances that can cause harm to human health or the environment, such as acids, bases, and toxic substances. Biological hazards involve organisms or substances produced by organisms that can cause adverse health affects, including bacteria, viruses, and fungi. Ergonomic hazards are related to the design of a workplace that can lead to musculoskeletal injuries, often due to repetitive motions or improper workstation setup.

Financial considerations, while important for operational management and risk assessment, do not constitute a physical hazard that could pose a direct threat to employee safety or health in the same context as the other categories. Hence, the focus is usually on hazards that lead to physical harm, rather than financial implications.
