| Title | Safety Equipment Failure of the Criticality Alarm System |
| Event Description | The public address system (criticality accident alarm) was impaired for a portion of the Building 310 warehouse and a subcontractor trailer. The cause of the impairment was determined to be the result of a contractor drilling into a public address system speaker wire while installing fire protection components in the Building 310 warehouse. This created an electrical short which rendered the speakers inoperable for a portion of the Building 310 warehouse and a subcontractor trailer. The speaker wire was obscured from view by a structural beam. The system was repaired, tested, and placed back into service by 1721 hours0.0199 days <br />0.478 hours <br />0.00285 weeks <br />6.548405e-4 months <br /> (EDT) on 6/30/2009.
