PREVENTING FREEZE UP - FROZEN
& BURST WATER PIPESCold weather freeze-ups can cause
vital fire protection systems to malfunction. Cold temperatures can cause
sprinkler piping to burst resulting in major water damage to buildings,
contents, and equipment. Pipes bursting can also impair automatic sprinkler
systems and leave a major portion of your facility without fire protection. A
fire during this situation may result in a major interruption to your business
and a huge loss. In the interest of preventing water damage claims for your property, designated key personnel should be aware of freeze protection and emergency preparedness procedures. Utilize the Winter Weather Precautions Checklist to assist with your risk control program. Best Practices include: Building temperature should be monitored, documented, and maintained at 55° F or higher

PREVENTING HEAVY ROOF LOADING & COLLAPSE Snow and ice build up can wreak havoc by placing additional loads on roofs, and supporting bearing members. Snow and winter storm event severity can be hard to predict depending on the location and geography of your facilities. It is best practice to plan ahead to have a written plan in place when the snow or ice arrives. Roofs collapse mainly due to weather patterns that produce a cycle of 2 events:
This rapid freeze and thaw cycling produce weighty snow/ice buildup that places excess stress on your roof. Flat roofs are especially prone to excessive accumulation and build up by the lack of natural grading, pitch and lack of runoff. Best practices include: Maintain all roofs and keep current with repairs. Winter weather will only further damage any underlayment and the damaging effects of water infiltration will be costly and may cause business interruptions. Arrange to have all roofs cleared of snow especially where snow drifts are visible. Hire a competent contractor for this dangerous task. Request contractor to clear any and all roof drains to allow for runoff and limit ponding especially on flat or relatively shallow pitched roofs. Clear pathways to the eaves in situations where there is a pitched roof without drainage pipes. PREMISES AND FIRE FIGHTING EFFORTSRemoval of accumulation of snowfall from your driveways, sidewalks and entryways is essential to maintain safe access to your facility by emergency responders. Clear all driveways, sidewalks, parking areas, access ways, bulkheads, portals, entryways and exits to allow for emergency to safely access your premises. Onsite fire fighting workers enhanced if hydrants are accessible and clearly marked with colored marker flags in high snow drifts. Unoccupied buildings:Vacant, idle, or otherwise “unoccupied” buildings or large buildings with unused space (compartments, floors, rooms, or basements, etc.) present another set of hazards that an organization must consider for best practice winter weather controls. Inadvertent releases of water, left unchecked or allowed to flow unnoticed, usually results in extensive interior damage. Best practices for these situations involve:
Unheated Space:
