Space Heaters Cause Fires

Heaters can cause house fires, and this is why experts will always recommend that you are conscious of switching off your space heater before you submit to the embrace of your bed.

Space Heaters Emit Carbon Monoxide

While many are so conscious of applying a couple of electric heater safety tips to prevent a house fire, they tend to be oblivious of the poisonous carbon monoxide that’s often discharged by space heaters. This gas kills in split seconds, and it’s fatal. What even makes it more deadly is that, unlike fire that you can quickly see and take action, there’s no way you can see, hear, or know if you’re breathing in this gas, and this is why many consider this gas to be a silent killer. Thus, note that you expose yourself more to get poisoned when you leave your space heater on overnight.
