  1. Take 5 for Safety E. Lessard March 3, 2015

  2. B930A, Emergency Installation of Fan to Prevent Freezing of Cooling Water Lines in Essential Equipment • The urgency of the repair was cold weather and subsequent water-line leak in critical Booster equipment • Their was inadequate heat in the area, and C-AD technicians installed a temporary, emergency fan to enable the distribution the steam heat • The temporary fix was judged later as something that does not demonstrate a code compliant temporary hookup • Upon identification of this situation, the temporary fan was disconnected and the wires cut by a C-AD Group Leader

  3. Temporary Electrical Fix NEC does not allow a splice in flexible wiring if it is not in a box

  4. Temporary Electrical Fixes • There were no injuries due to the installation and use of the temporary, emergency fan • The National Electrical Code (NEC) allows for temporary, emergency measures that are electrically safe but not code compliant • NEC 590.3:C Emergencies and Tests. Temporary electrical power and lighting installations shall be permitted during emergencies and for tests, experiments, and developmental work. • Have temporary, emergency, electrical fixes approved by the C-AD Chief Electrical Engineer, or his designee, at installation or as soon as practicable (assuming such repair may have to be done on off-hours)

  5. Look for Hazards in Every Direction – Weather • Light snow starting around 4 pm today with steady snow arriving around 6 pm but temps remain above freezing going into Wednesday morning with rain continuing into late night • Early Thursday morning we start to get the heavier amounts of snow that will last most of the day with dropping temps • Hazards • Flooding on streets and around buildings • Water accumulating and freezing • Survey drainage areas around C-AD buildings and send issues to F&O FOC (x2468)
