Knowledge Test POH is broken up into two distinct variables called P1 and P2: • P1: Probability of a hazardous situation occurring: what's the probability that all the stuff leading up to a hazardous situation occurs? In our fridge example: whats the probability that someone eats the food in the fridge (hazardous situation)?

Risk = Severity of Harm (S) x Probability of Occurrence of Harm (POH).

P1 probability of the hazardous situation occurring is probably LOW.

• P2: Probability of hazardous situation leading to harm: what's the probability that, even if the hazardous situation has occurred (you ate the food!), the harm will occur (i.e. you do get sick)? In our fridge example: let's say for some reason you arrive home inebriated and you ignore all rational cues and eat the food. Does that automatically mean that you get sick?

P2 likelihood that the harm will occur (i.e. that you'll actually get sick even if you ate the food) is also probably LOW.
