Building a Robust Defense:
Multi-Phased Approach
• Checklist - Pre-Season
• Checklist - Pre-Storm
• Checklist - Daily - Valve Stroke / Pump Start / Instrument
• PM Tasks in CMMS Database
• Converting Temporary Solutions to Permanent Solutions
• Changing Conditions (Plant and Weather)
7
COLD WEATHER PREPARATIONS AND BEST PRACTICES
Planning:
• Use CMMS PM as a triggering tool
• “Pre-Season” Checklist/Procedure
• Content Example:
• “Begin use of daily 32 degree action log”
• “Order Salt and Sand, Stage shovels”
• “Test Snow Blower, Torpedo Heaters
• “Buy #2 Fuel or Propane” for heaters
• “Set up Plowing Contractor”

COLD WEATHER PREPARATIONS AND BEST PRACTICES
Planning:
• Daily “32 Degree Action Log”
• Daily checks for CRO and Outside Operators
• Avoid Ambiguity
Poor:
“Start Circ water Pump’
Better:
“Start Circ Water Pump
“Verify Flow on XMTR xxx-xx-xx”
“Verify Pressure on XMTR xxx-xx-xx”
