Q

Give an example to demonstrate the difference between a hazard and risk

A hazard may be a tight bend in the road. This hazard creates a risk of crashing your vehicle when turning around the tight corner.

Q

How can we estimate risk?

A

Calculating how many times the risk happens in a large sample of events.

E.g. how many crashes occur in a group of 100,000 drivers in a year

As well as looking at the probability of harm, risk estimation also considers how serious the harm is (e.g. the risk of death is worse than the risk of a headache)

Q

Give an example of a low-risk and high-risk activity

A

Low risk: going for a walk. Small chance of falling and hurting yourself, and even if you hurt yourself it is likely to be a minor graze

High risk: sky diving. The chance of parachute failure may be small, but the consequence would be severe

Q

How do you minimise risk in experiments? GIve an example.

A

Identify hazards, then make plans to reduce the risks of those hazards

E.g. if you are doing an experiment with acid, then the acid is a hazard. You can minimise the risk of harm from the hazard by wearing gloves and goggles.
