APPENDIX 1

Step 6: Determine the Need for Locking or Barricading Buildings and the Priorities for Notification.

  1. If conditions 1 through 4 of the preliminary evaluation criteria (see Table 1) have been met, make sure everyone is out of the building, lock the building and prevent access.
  2. If conditions 5 through 8 of the preliminary evaluation criteria exist (see Table 1), then the hazard area must be barricaded or locked to prevent access. If the potential falling hazard or hazardous material is outside the building, some form of barricading should be established to make students, faculty and staff aware of the hazards and keep them away from the condition. If the conditions exist inside the building, locking the building to prevent access should be sufficient.
  3. Explain the locked and/or barricaded areas to faculty, students, staff and parents. Post an explanation of the reasons for locking the area near the entrance and include a contact name and phone number for parents, teachers and post-earthquake inspection engineers.
  4. Report the school site condition to the school district.
  5. If it becomes necessary to reoccupy some of the school buildings before a structural engineer has evaluated the safety of the building, do not occupy obviously unsafe structures. Reoccupancy of gymnasiums and multipurpose rooms is not encouraged as these structures are more difficult to inspect and generally are subject to higher stresses than individual classroom buildings. More modern buildings are generally more earthquake-resistant than older buildings.

CAUTION: Aftershocks can cause additional damage. After each significant aftershock, all occupied buildings should be re-inspected.

 

TABLE 1 PRELIMINARY EVALUATION CRITERIA

This table will be used to determine the condition of a building and to give guidance on appropriate action.

CONDITION ACTION
1. Building has collapsed, partially collapsed or moved off its foundation. Do Not Occupy
Prevent Access
2. Building or any story is leaning significantly. Do Not Occupy
Prevent Access
3. Obvious severe damage to primary structural members, severe leaning of walls or other signs of severe distress present. Do Not Occupy
Prevent Access
4. Large cracks in ground, massive ground movement, or slope displacement present which are under, or near, the building and are a hazard to the building. Do Not Occupy
Prevent Access
5. Obvious parapet, chimney or other failing hazard present. Barricade to Prevent
Access to the Area
6. Other hazard present (e.g., toxic spill, chemical spill, asbestos contamination, broken gas line, fallen power line). Barricade to Prevent
Access to the Area
7. Air duct terminals, ductwork, light fixtures lenses or florescent bulbs fallen or dislodged. Broken windows. Overhead mechanical equipment supports or bracing dislodged. Barricade to Prevent
Access to the Area
8. Although no damage is yet apparent, areas with overhead elements similar to those indicated above may also fall in an aftershock so they are a possible hazard. Barricade to Prevent
Access to the Area
