I have got into the idea of giving you 2 paragraph they are as follows (you can choose any one)
A hazard is a situation that poses a level of threat to life, health, property, or environment. Most hazards are dormant or potential, with only a theoretical risk of harm; however once a hazard becomes “active”, it can create an emergency situation. A hazard does not exist when it is not happening. A hazardous situation that has come to pass is called an incident. Hazard and vulnerability interact together to create risk.

An accident is caused by somebody’s action even if it was intended or unintended.
A hazard is caused by a particular set of circumstances which could be avoided or foreseen, hazards could become a threat or risk to health or life. Most hazards cause accidents – for example, in my nursery a girl was riding a scooter and accidently run into another child causing a big graze on the other child leg. This specific situation shows a typical accident, the accident was caused by her being excited and not careful in her actions. The girl was not aware of what her actions (driving fast on a scooter) can cause .
