The document discusses quantifying risks from hazards like hurricanes, dust explosions, and meteorites that could threaten the 100 residents of a building. It explains that to quantify the risks, the likelihood (annual frequency) and consequences (potential fatalities) of each event need to be estimated. Once quantified, the risks can be displayed on a risk matrix based on their expected value (frequency multiplied by fatalities), or plotted on a frequency-number (FN) curve showing the relationship between event frequency and potential fatalities. An example risk matrix is given showing the estimated annual frequency and potential fatalities for hurricanes, dust explosions, and meteorites to demonstrate how these risks can be quantified and compared.
