Turning On the Space Heater for the First Time This Fall? Do These 7 Things First

The first cold night of fall always sneaks up on you. Suddenly you are digging through the closet for the little space heater you stored back in March.

Before you plug it in, take ten minutes. Space heaters are one of the easiest ways to warm a single room, but they are also one of the most common ways a cozy night turns into a house fire. The good news: almost every serious risk is avoidable with a few simple habits.

According to the U.S. Consumer Product Safety Commission (CPSC), portable space heaters are linked to roughly 1,700 fires, 80 deaths and 160 injuries in the United States each year. The National Fire Protection Association (NFPA) lists heating equipment as one of the leading causes of home fires, and nearly half of home heating fires happen in December, January and February.

The most striking number comes from an NFPA report covering 2011 to 2015: space heaters were involved in 43% of home heating fires but 85% of home heating fire deaths. And more than half of those deaths started the same way, with heating equipment placed too close to something that could burn.

1. Inspect It Before the First Use

A heater that sat in a garage or closet for seven months deserves a quick check-up:

• Look at the cord and plug for cracks, fraying or scorch marks.

• Vacuum or wipe away dust and lint from the grille.

• If anything looks damaged, replace the heater. A new one costs far less than the alternative.

2. Follow the 3-Foot Rule

This is the single most important habit. Fire safety experts recommend keeping a space heater at least three feet (about one meter) away from anything that can burn. That includes:

• Curtains and drapes

• Beds, blankets and pillows

• Sofas and upholstered chairs

• Paper, laundry, rugs and pet beds

3. Plug It Directly Into the Wall

Space heaters draw a lot of power. The CPSC and NFPA both advise plugging them directly into a wall outlet, never into an extension cord or a power strip, which can overheat. Also:

• Push the plug in all the way so it fits snugly.

• Do not run the cord under a rug, where heat can build up and damage goes unseen.

• If the outlet or plug feels hot to the touch, stop using it and have an electrician take a look.

4. Put It on a Hard, Level Floor

Set the heater on a flat, hard, nonflammable surface where it will not be knocked over by a pet, a child or a passing foot. Keep it out of walkways and away from doorways, so it never blocks an exit in an emergency.

5. Turn It Off When You Leave or Sleep

It is tempting to let the heater run all night, but safety agencies are clear: turn it off and unplug it when you leave the room or go to bed. If you need warmth while you sleep, a heavier blanket or warming the room before bedtime is a safer approach.

6. Check Your Alarms Tonight

Heating season is the perfect reminder to test your smoke alarms. The CPSC recommends:

1. Test smoke and carbon monoxide alarms every month.

2. Replace batteries at least once a year.

3. Have smoke alarms on every level of your home and inside each bedroom.

4. Install carbon monoxide alarms on every level, outside sleeping areas.

Carbon monoxide is a special concern with fuel-burning heaters (kerosene, propane or gas). If you use one, follow the manufacturer's ventilation instructions exactly, and never use outdoor heaters or grills inside.

7. Buy Smart If You Need a New One

If your old heater is past its prime, look for these features on the box:

• A certification mark from a recognized testing lab, such as UL, ETL (Intertek) or CSA

• Automatic tip-over shut-off

• Overheat protection

• A built-in thermostat, so it does not run at full power all the time

• A heater sized for the room you actually want to warm

The bottom line: a space heater can make a chilly room comfortable. It just needs a little respect: three feet of clear space, a wall outlet all to itself, a hard floor, and an "off" switch when nobody is watching.
