Q. Where can I view the HayWired Earthquake Scenario that David mentioned?

A. You can view it at https://www.youtube.com/watch?v=aRLb3PmIYFc&t=2s. The HayWired earthquake scenario, led by the U.S. Geological Survey (USGS), anticipates the impacts of a hypothetical magnitude-7.0 earthquake on the Hayward Fault. The fault is along the east side of California’s San Francisco Bay and is among the most active and dangerous in the United States, because it runs through a densely urbanized and interconnected region. Get Ready! Analyses of impacts related to the HayWired earthquake scenario include estimates for potential fatalities, injuries, water outages, fires, and other major disruptions. These could potentially include: 800 deaths, 16,000 nonfatal injuries, property and direct business interruption losses of more than $82 billion from from shaking alone. The USGS and its partners are working to energize residents and businesses to engage in new and ongoing efforts to prepare the region for such a future earthquake.

Q. What kind of fire extinguisher should I have in my house?

A. You should purchase a fire extinguisher that has a minimum rating of 2-A, 10-B:C. The A rating is for trash, wood and paper fires. The B rating is for liquid fires and the C rating is for electrical fires The numbers indicate how much of the fire can be put out by the fire extinguisher. Every number before the A means it is as effective as 1 ¼ gallons of water. For example, 2A means the fire extinguisher is as effective as 2 ½ gallons of water, and so on. The numbers before B and C are a measure of the amount of square feet the fire extinguisher can put out. For example, a 10:BC fire extinguisher can extinguish a fire over 10 square feet. Also, a metal handle on the extinguisher is preferable which means that extinguisher can be serviced. Dispose of old extinguishers at your local Recology hazardous waste site.

Q. Is the small fire extinguisher that contains gas that I purchased for my computer work area OK to have?

A. That type of fire extinguisher may only be rated for Type C electrical fires. It would be better to get an all purpose fire extinguisher with a minimum rating of 2-A, 10-B:C.
