Reliable heating systems are crucial during winter, and especially during a storm or deep freeze. Here are tips to maintain heating, provided by the engineering team at HSB Canada.

1. Keep your building and equipment warm

Heating systems are the lifeline of your operations during cold conditions. If they fail, disaster could strike.

  • Insulate all piping. Install new and replace damaged insulation where necessary, and don’t forget the sprinkler system.
  • Inspect all outside dampers for proper operation. Dampers are designed to keep cold air out.
  • Clear and protect all outside vents from ice and snow accumulation. 
  • Heat requires power. If generators are unavailable, make arrangements to obtain non-electrical portable heating during outages. 
  • If you have electric heat tracing (pipe surface heating), make sure that it is energized, and also be prepared to supply back-up power to heat tracing systems.

2. Safeguard business equipment during power outages 

Power surge and sag protection is necessary at all times – especially during freezing conditions. Severe weather can cause power loss and downed wires, disrupting your operation’s power supply. When electricity is restored, the sudden surge of power can destroy the modern, high-tech equipment you rely on.

  • Unplug it. Anticipate power sags and surges during severe weather. The best solution is equipment isolation – turn it off and unplug it. If you need to keep equipment running, installing surge protectors can provide protection. 
  • Prepare for power outages. If you rely on generators for back-up power, perform pre-operational checks and start-up tests. Consult your generator’s manufacturer for details.  

3. Protect your building 

If you are facing extreme temperatures within 24 hours, protect your building and prepare your emergency response team before cold weather and freezing temperatures arrive. 

  • Inspect the building. Close all windows, doors and outside dampers. Schedule regular building checks during storms and cold weather. Arrange for snow and ice removal, including the roof. 
  • Who’s responsible? Designate personnel to monitor weather conditions using weather services in the area. Create and train your emergency response team. Successful loss prevention programs require the support of all parties involved, including senior management and facilities/maintenance teams. 
  • Provide emergency telephone numbers. Collect and distribute a list of emergency phone numbers and contacts, such as snow removal, heating system repair company, utility company, and the weather bureau. 
  • Anticipate flooding. Severe and cold weather can cause flooding. Move susceptible equipment or stock to an alternate location, where water cannot reach it. 
  • Always have cold-weather gear on hand. Provide gloves, hats, emergency blankets, and flashlights, and make sure your people know where they are stored.
