And we've nowadays taken it even further, in spoken Finnish we've even got rid of the "hän" and mostly use "se", which is the Finnish word for "it". The same pronoun is used for people in all forms, animals, items, institutions and so on, and in practice the only case for "hän" is people trying to remind others they consider their pets human.
Context will tell which one it is.
It's safe enough, in the Finnish army we occasionally get the tent heater red hot, and as long as nothing flammable touches it or is too close, it's fine. It will radiate heat quite well when that hot, but won't be anywhere close to dangerous if you know what you're doing. In the tent we of course have some water nearby to extinguish the possible flames but still.
You basically need to have it glowing red if you're to keep the tent warm in -15 °C or lower. - 30°C needs something closely resembling the picture posted.
