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:
“There is no calamity which a great nation can invite which equals that which follows a supine submission to wrong and injustice and the consequent loss of national self-respect and honor, beneath which are shielded and defended a people’s safety and greatness.”
—Grover Cleveland (1837–1908)
“Can we not teach children, even as we protect them from victimization, that for them to become victimizers constitutes the greatest peril of all, specifically the sacrifice—physical or psychological—of the well-being of other people? And that destroying the life or safety of other people, through teasing, bullying, hitting or otherwise, “putting them down,” is as destructive to themselves as to their victims.”
—Lewis P. Lipsitt (20th century)
“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 (1817–1862)
