Stop These 3 Decorating Mistakes Before They Turn Into Serious Safety Hazards

Finding the appropriate layout for a room can be tricky. There are numerous details to consider, including traffic flow and walkways, the room's functionality, the number of people to accommodate, proximity to electrical outlets, and more. But that’s not all we need to be thinking about when we decorate—safety should always come first. Failing to consider essential safety factors can create significant hazards, including too-small walkways, obstructed exits and windows, and unsafe cord management. If any of this sounds like something you’ve neglected to consider, read on to learn about the most common decorating hazards and how to fix them.

1. Blocking HVAC Vents or Radiators

Placing furniture directly in front of air vents, returns, baseboard heaters, or radiators can have a significant negative impact on your home’s heating and cooling systems. While it can be tempting and space-efficient to push that sofa right against the wall, it’s essential to make sure you’re not blocking an air return vent or heating mechanism.

For HVAC air return vents, restricting airflow requires your HVAC system to work harder, which wastes energy, increases utility bills, and severely impacts the system's lifespan. Covering vents and registers prevents the air from circulating properly, which can create cold spots in winter or hot spots in summer. Not only is this uncomfortable, but it can also confuse your thermostat. When it comes to baseboard heaters or radiators, placing upholstered pieces (such as furniture, drapes, or other flammable materials) too close can cause overheating, which, over time, can lead to smoldering. 

The Fix

For HVAC vents and registers, maintain a clearance of at least 12 inches in front of them. If this is not possible, use plastic vent deflectors to redirect airflow. For baseboard heaters, keep upholstered items and fabrics at least 6 inches away to avoid heat accumulation. 

2. Blocking Exits, Escape Routes, and Windows

Large couches, dressers, console tables, or shelving that block doors, hallways, or emergency exits can have serious consequences. Not only does their placement impact traffic flow, but if hallways or doorways are blocked by furniture, this can waste precious time when trying to escape in the event of a fire or other disaster. During a fire, visibility significantly reduces, meaning people might trip, become disoriented, or waste valuable time trying to find their way around. Not only that, but if emergency crews need to access these areas, they might have trouble maneuvering a wheelchair or gurney through the narrow passage.

Windows blocked by large furniture not only eliminate the benefit of natural airflow, but are also difficult to open in case of smoke or overheating. If something like a bed or shelving is blocking the window, it can become almost impossible to escape in the event of a fire or other disaster. Lastly, legally, blocking exits goes against fire codes and could even lead to fines or issues during inspections (especially in rental properties). 

The Fix

Ensure you have at least 36 inches of space in hallways (42 inches is preferable) and in front of doors for easy and safe evacuation. Keep window latches accessible, and avoid placing large furniture in front of them to prevent obstruction. Then, make an emergency escape plan. Act out your own fire or emergency drill: map out your routes, and determine if there are any possible roadblocks. Re-run these routes regularly, at least once every three months (and especially during the holiday season, where Christmas trees and other decor can significantly impact flow).

3. Cords Under Rugs or Behind Furniture

One of the most common “invisible” design shortcuts is hiding cords under rugs, behind furniture, or wedging them along baseboards where they are not visible. While it might improve the look of a room, this habit creates one of the most overlooked fire hazards in the home. Electrical cords generate heat when they’re used, so tucking them under furniture or other places with no airflow greatly increases the risk that they might overheat. 

Cords hidden under rugs pose a greater risk as they are constantly stepped on, rolled over by chairs, or pressed into the floor. This repeated pressure can weaken insulation, exposing wires that increase the risk of sparks or shocks. Hiding cords behind furniture is just as dangerous. Because cords are tucked out of sight, damage often goes unnoticed until it’s too late. A frayed cord under a rug or behind a large armoire might not be discovered until the smell of burning or a circuit trips.

The Fix

Protect cords using proper cord covers or concealers, which are easily found at your local hardware store. Many are paintable, so you can easily disguise them with your existing decor. Avoid wedging cords tightly behind heavy pieces, such as couches or dressers. Always leave a gap for air circulation and easy access in case cords need inspection or replacement. Regularly check cords for cracks, bends, or signs of overheating, especially in frequently used items such as lamps, space heaters, or electronics. Replace damaged cords immediately.
