To protect your business from the effects of cold weather, here are some things to keep in mind:Monitor temperatures every few hours in vulnerable areas. Add low temperature alarms that are connect to a constantly monitored location. Very that water-filled sprinkler piping is maintained at a minimum temperature of 40 degrees. Inspect valve enclosures for pre-action and deluge valves on a daily basis to verify a minimum temperature. Provide approved portable heaters for vulnerable areas that might fall below 40 degrees. Use tarps to erect temporary wind breaks. For a permanent wind break, consider planting evergreen trees and hedges upwind (prevailing winter wind direction) of vulnerable buildings and equipment. For pipes that are vulnerable to freezing, open water faucets slightly to let them drip to keep water flowing. If pipes freeze, turn off the water supply and thaw or repair damaged piping. Do not use open flame devices to thaw frozen pipes or equipment. Verify that all fire protection equipment is in service. Constantly monitor any boilers or other heating systems that must remain online. Keep names and phone numbers of your heating contractor, plumber, and fire department easily accessible.
