Following are the 5 factors that cause health and safety hazards:


The first factor that can cause a H&S hazard is people. People’s actions, whether they display them or not, have a significant impact on workplace health and safety. Therefore, actions become one of the major factors that cause health and safety hazards.

People play a major role in connecting with the other four factors in their own unique way. Hence, a Job Hazard Analysis (JHA) becomes crucial. It helps understand the tasks based on the process flow.

Equipment include tools and machines that people work with. Further, equipment includes those to which people are near. Equipment can include fixed machines, vehicles, material handling devices, hand tools, protective equipment, and personal gear.

Further, unsafe or poor conditions such as overcrowding and poor ventilation become important. Furthermore, hazards caused by physical agents such as light, temperature, and noise are vital to analyze. It is important to consider housekeeping hazards such as spilled cleaning fluids, since they can be inhaled. Maintenance hazards such as blocked stairs, debris on stairs, and blocked floors and exits are critical for hazard analysis.
