Understanding Hazards and Risks

The video tutorial explains the difference between a hazard and a risk. A hazard is anything that can cause harm, while a risk is the potential for that hazard to cause harm. Examples include a ladder as a hazard and falling off it as a risk. The video also covers how to assess risks by evaluating the likelihood of exposure and the severity of potential outcomes. An example is given using a poisonous spider in a jar, illustrating how risk ratings change with circumstances.

What is the primary distinction between a hazard and a risk?

• A hazard is a potential event, while a risk is a certain event.

• A hazard is anything that can cause harm, while a risk is the likelihood of that harm occurring.

• A hazard is a type of risk, while a risk is a type of hazard.

• A hazard is always man-made, while a risk is natural.

Which of the following is an example of a risk?

• A hammer

• Climbing a ladder and falling

• A plane

• A ladder

What factors are considered when assessing the likelihood of exposure to a hazard?

• The size and color of the hazard

• The probability and frequency of exposure

• The cost and availability of safety equipment

• The legal implications of the hazard

What does the severity of a risk refer to?

• The number of people affected by the hazard

• The cost of mitigating the hazard

• The time it takes for the hazard to occur

• The range of potential consequences resulting from the hazard

In the example of the poisonous spider, what changes the risk rating from minor and remote to probable and imminent danger?

• The spider being in a different room

• The spider being in a closed jar

• The spider being outside the jar

• The spider being non-poisonous

How does changing the circumstances of a hazard affect its risk rating?

• It only increases the risk rating.

• It only decreases the risk rating.

• It can increase or decrease the risk rating.

• It does not affect the risk rating.
