Department of Emergency Management (DEM)
We manage everyday and not-so-every day emergencies in San Francisco: Emergency Services: We help San Francisco prepared for any emergency and we coordinate response and recovery. Emergency Communications (9-1-1): When people in San Francisco have police, fire, or medical emergency our dispatchers are the first people they call. Homeland Security Grant Management: We manage homeland security priorities for the San Francisco Bay Area.

Department of Building Inspection (DBI)
Emergency Preparedness Coordination DBI Emergency Operations Plan Conduct training as Disaster Service Workers Specialized training for Safety Assessment Program Building Occupancy Resumption Program (BORP)
9
Mitigation: DBI’s Programs
Parapet Safety Program (1972) Unreinforced Masonry (1989) Buildings Program (1992) Soft Story Retrofit Program (2014) Voluntary seismic retrofit
10
Mitigation: Building Occupancy Resumption Program (BORP)
Allows building owners to arrange for private post-earthquake inspection Requires contracting with qualified engineers Includes a building-specific inspection plan Deputizes engineers to post buildings after quake
11
72 HOURS In a serious emergency, city services will be impacted, so a basic rule of thumb is to be able to take care of each other for 72 hours before help arrives. read the slide

What You Can Do to Prepare
13
What You Can Do to Prepare
Discuss all possible exit routes from each room, building and neighborhood Decide where you will reunite after a disaster. Conduct emergency drills and practice “DROP, COVER and HOLD” Always keep your car’s gas tank at least half full DEM
14
Preparedness: Property Owner
How can I prepare my property? Owner hires a civil or structural engineer to develop a plan/report identifying how occupants can safely enter the building to remove their possessions. Owner hires contractor whose staff retrieve possessions for the tenants.
15
Structural Home/Building Preparedness
Evaluate your structure Underlying soil conditions Age and type of construction Structural /connection condition Remodeling impact Investigate retrofit options Compare retrofit costs with insurance premiums
16
Bolt Sill to Foundation Using Square Plate Washers
Square plate washers perform better in quakes than the round one that has been replaced here. They also make the tightening of expansion bolts easier. Plate washers must be a minimum of 2” x 2” x 3/16” thick
17
Strengthen Cripple Walls
Crawl Space Cripple Wall First Floor A cripple wall is generally the weakest part of older building because it has insufficiently strong sheathing materials. This can cause full or partial collapse in an earthquake. These areas can be strengthened for relatively low cost by correctly applying plywood sheathing to the cripple walls.
18
Non-Structural Mitigation
Parapets Chimneys Water heaters Light fixtures Furniture Cabinets Appliances Electronics
19
Preparing Your Home: Water Heater
Earthquake strapping of water heaters California law requires your water heater be properly braced so it won’t tip over in an earthquake Source of water during emergency
20
Preparing Your Home: Smoke Alarms
Be sure your home’s street number is visible from the street, so emergency vehicles can find you. Install a smoke alarm in each sleeping room Provide a smoke alarm outside of each sleeping area Install a smoke alarm on each additional living level. Keep at least one ABC type fire extinguisher on each level of your home.
21
Response: City/At-Large Early Stages
Evacuating/extracting people from buildings Route recovery/traffic control Mitigation of immediate public hazards Restoration of critical services Lighting of field work sites Debris clearance Inspection of critical facilities DEM
22
DBI’s Response Coordinate with DPW for inspection of critical facilities and City buildings Supervise inspection of private buildings Verify red-tagged building status Re-inspect buildings under construction Issue emergency repair permits Inspect earthquake building repairs 72 hour window
23
DBI Manages Safety Assessment
24
Resident’s Response Listen to public messaging (KCBS/KGO radio)
If safe to do so, stay at property Check in with neighbors Call 911 only for emergencies Carry out preparedness plan
25
Utilities: Natural Gas
Train family to turn off utilities, if necessary Teach children to identify the smell of gas Turn off gas, if: you smell leaks & are unsure your meter wheels are spinning Be aware that you may not have service for weeks
26
Utilities: Electricity
Turn off electricity, if: you smell gas leaks wires are broken walls are badly damaged
27
Turn circuit breakers to OFF position
28
Or pull fuses
29
Utilities: Water Turn off water if house is flooding or if water is contaminated Shut Off Water, If Necessary Locate water shutoff Insert tool in hole & remove cover Turn water OFF
30
Road to Recovery Rapid organized response by DBI to conduct building damage assessment post event Request for Mutual Aid to augment DBI personnel as approved by the Mayor Timely processing of repair permits DBI inspection of damage repairs Swift resumption of new construction plan review and inspection
31
Remind Yourself Drill with your family at least once a year; earthquake anniversaries are good reminders Maintain first aid and other emergency skills Check family emergency supplies, replenish them as needed
