Baseboard heaters are generally safe and efficient, but they can be dangerous if safety precautions are not followed. To ensure safety, do not block the heaters with furniture, drapes, open doors, or other items, and maintain clear space around them for proper heat flow. Regularly check that items have not fallen on or under the units. If you have children or pets, make sure they stay clear of hot heaters to avoid burns. For added safety, consider models with an automatic shut-off feature and have them professionally tested. If a problem occurs with a baseboard heater, always contact a qualified electrician or HVAC professional for repairs.

A spark arrestor is a simple metal mesh device that prevents flammable particles from escaping from a combustion source and causing a fire. You typically find these attached to gas or diesel engines on things like cars, generators, and garden tools (lawnmowers, chainsaws, etc.). Fireplace or wood-burning stove chimneys also have spark arrestors attached to or sitting under the chimney cap to capture burning embers.

Some Christmas lights are marked as being “UL Safety Certified” or Underwriters Laboratories Safety Certified. This lab is a trusted source for determining the safety standards of electrical products—you should make sure your Christmas lights have this label. Brush up on other electrical safety tips before installing any lighting features.
