Safety
Electric fan heaters are unsealed appliances with live electric parts inside, so are not safe to use in wet or very humid conditions, due to risk of a short circuit leading to fire, or electrocution due to access to electrically live parts. Electric fan heaters usually have a thermal fuse close to the element(s) to protect against fan failure causing overheating and possibly fire. Steel-cased heaters perform better in potential fire-causing faults than plastic-cased ones, since the case will stay whole and not burn.
Portable fuel-powered fan heaters release all the fumes of combustion into the room, creating a risk of poisoning by carbon monoxide and carbon dioxide. Most installed fuel fan heaters in the first world use a heat exchanger and external ventilation, avoiding this risk, and dumping the water vapour from combustion outdoors.

Famous quotes containing the word safety:
“For hours, in fall days, I watched the ducks cunningly tack and veer and hold the middle of the pond, far from the sportsman;... but what beside safety they got by sailing in the middle of Walden I do not know, unless they love its water for the same reason that I do.”
—Henry David Thoreau (18171862)
“An evident principle ... is the principle of justice to all peoples and nationalities, and their right to live on equal terms of liberty and safety with one another, whether they be strong or weak.”
—Woodrow Wilson (18561924)
“The high sentiments always win in the end, the leaders who offer blood, toil, tears and sweat always get more out of their followers than those who offer safety and a good time. When it comes to the pinch, human beings are heroic.”
—George Orwell (19031950)
