Hazards are everywhere. A knife is a hazard. A needle in a hospital is a hazard. A gun is a hazard. Everyone of what i have given as examples are necessary in some walk of life.
In Other Words, We cannot have a hospital without a knife or a needle as they are needed to treat a patient. A Gun is an essential tool for someone working in the army or high security police for example.
However if the hazard is in a persons hand's or at a time or in an situation where it is not expected to be, then the hazard can cause an incident. For example a kitchen knife in a child's hand, a gun in the hands of anti social, or water on a mosaic or marble floor.
However not every time the hazard is in this situation will cause an incident. There you have to calculate the risk of such an incident. For example not every time you travel in a road, one is involved in an accident. you have to view every object in the line of your travel such as a bus, lorry or even a dog on the road as hazard.
When travelling, you take a risk by crossing these hazards to reach your destination. You minimise the risk by driving slowly, taking extra care at nights, not drinking alcohol before you drive and so forth.
However you do not want to take any risks in some areas such as not giving a knife to a child as the risk though may be small, is too much to take.
Back to wherever you work, you start looking at things with a note of
1. Are there hazards
2. What is the exposure
3 What is the risk
4 Should i take the risk or not
5. Can i reduce the risk or avoid the risk altogether by avoiding the exposure altogether
Hope it makes sense
It would certainly make sense if you start applying.
You then ask the cleaner to put a notice that the floor is wet when he is cleaning to warn the people walking by that there is a small risk of falling and they have to walk more carefully.
All of us would put our waste in a bin and dispose appropriately to reduce the breeding of bugs which then would cause infection and so on and so forth
