We can depict a hazard as a potential source of danger which poses a potential threat to an individual or a serene situation that needs to be looked into by any institution in the place of work or rather at home too. Hazards prevent the normal running and operation of duties or production in an industry hence resulting in additional costs that are unnecessary or those that could have been prevented. Probable operability problems as well as potential hazards are thus predicted basing on the historical occurrences of such hazards and events. It is thus through these studies that intuition and ideal situational judgement is stimulated in a team work effort to solve such problems and prevent them before they happen through proper hazard prediction and pre-planning for hazard prevention systems.

I have come to understand from my fellow colleagues that if a hazard is not looked into and it comes to pass or the threat becomes real, it becomes an incident while on the other hand a risk is created if the hazard is eminent. I have also come to learn that we have different modes of hazards that pose threat to situations. The first mode is that of dormant nature. This is a hazard that in case of occurrence of the incidence, no property or people can be affected directly. Secondly, we have the armed mode of potential hazard that involves probability of people, environment and property is probable to be directly affected. Finally we have the active mode that involves the threat already starting to affect people and property for example the spread of Ebola in West Africa.


Hazards are exhibited in different forms and types. Physical hazards is one type that has a potential of inflicting harm on people physically as well as adverse stress. In this case, these hazards are either natural or man-made. These could be for example earthquakes in urban areas where people die or even a place where terrorists attack and shoot people.

Chemical hazards looks into potential damage of the body caused by foreign substances introduced to the body. These substances could be chemicals that are toxic and inflict harm to the body for example poisonous gas leaked to people. These are also either natural or man-made.

Other times we experience potential psychological hazards that lead to people becoming harmful to others as a result of stressful situations that may be inflicted upon individuals. Individuals that are under influence of drugs and alcohol can become hazardous to people as a result of psychological effects. We also have biological and radiation hazards. Biological hazards are caused by parasites, bacteria, fungi, viruses and other toxins. Both damage human cells and tissues.

Participating in these group discussions has created a very great teamwork among the group members creating ease in sharing of knowledge in terms of hazards. This has given me a chance to learn more from the extensive research done by my colleagues as well as sharing what I know with them. I have come to know the different types of hazards as well as using the historical events to try and prevent them.

Extensive research should also have been done on the way these hazards are prevented as well as their root cause. Another approach should have been taken such as live face to face discussions so as to really pass the points strongly from one person to another and made corrections and agreements on the conflicting points.


Group discussions allow students to share knowledge at ease as well as develop ideas on their own as well as creating a chance for critical thinking among the students
