## What is a 5×5 risk matrix?

Because a 5×5 risk matrix is just a way of calculating risk with 5 categories for likelihood, and 5 categories severity. Each risk box in the matrix represents the combination of a particular level of likelihood and consequence, and can be assigned either a numerical or descriptive risk value (the risk estimate).

## What are the 4 risk levels?

The levels are Low, Medium, High, and Extremely High. To have a low level of risk, we must have a somewhat limited probability and level of severity. Notice that a Hazard with Negligible Accident Severity is usually Low Risk, but it could become a Medium Risk if it occurs frequently.

## What are the 10 P’s of risk management?

These risks include health; safety; fire; environmental; financial; technological; investment and expansion. The 10 P’s approach considers the positives and negatives of each situation, assessing both the short and the long term risk.

## How is risk rating calculated?

Risk score is a calculated number (score) that reflects the severity of a risk due to some factors. Typically, project risk scores are calculated by multiplying probability and impact though other factors, such as weighting may be also be part of calculation.

A risk assessment is the process of identifying what hazards currently exist or may appear in the workplace. A risk assessment defines which workplace hazards are likely to cause harm to employees and visitors.
