Which of the following are the three main categories of hazards?

The identification of hazards in the workplace is essential for maintaining safety and health standards. The three main categories of hazards encompass physical, chemical, and biological hazards, which are critical to understand for effective risk assessment and management.

Physical hazards include environmental factors that can harm an employee, such as slips, trips, falls, and exposure to harmful conditions like extreme temperatures. Chemical hazards refer to substances that can cause harm, including toxic chemicals, flammable materials, and corrosive agents. Biological hazards originate from living organisms or their products, including bacteria, viruses, fungi, and other agents that can lead to infections or health issues.

Recognizing these categories helps in implementing appropriate safety measures, ensuring that workplaces are designed and maintained to minimize risk and protect employee health. The other options do not encompass the most recognized classifications used in occupational health and safety, which is why they do not represent the three main categories of hazards. Understanding these distinctions is vital for effective safety training and hazard communication in various industries.
