The correct answer identifies the four types of hazards as chemical, physical, biological, and ergonomic hazards. This categorization is fundamental to workplace safety and health standards established by OSHA.

Chemical hazards involve exposure to harmful substances that can cause health issues, ranging from short-term effects like skin irritation to long-term effects such as respiratory problems or cancer. Understanding these hazards enables workers to implement appropriate safety measures, such as wearing personal protective equipment (PPE) and using proper ventilation when handling chemicals.

Physical hazards pertain to environmental factors that can cause harm, such as noise, radiation, extreme temperatures, and working from heights. These hazards can lead to immediate injuries or chronic conditions, emphasizing the importance of safety protocols in the workplace.

Biological hazards refer to organisms or substances produced by living organisms that can pose a risk to human health, such as bacteria, viruses, mold, and fungi. Awareness and training about biological hazards are crucial in environments like hospitals and laboratories where exposure risks are higher.

Ergonomic hazards are related to how work is designed and can lead to musculoskeletal disorders. These hazards arise from awkward body positions, repetitive movements, or excessive force, highlighting the need for ergonomic assessments in the workplace to enhance employee well-being and productivity.
