"Hazards of kerosene use include poisoning, fires, and explosions. As well, some kerosene lamps emit fine particulates, carbon monoxide, nitric oxides (NOx), and sulfur dioxide when burned. These by-products may reduce lung function and increase risks of asthma and cancer."

"Oil lamp or lantern: The safety of oil lamps is pretty much the same as for candles. Never leave it unattended, extinguish it before you go to sleep, keep it away from children and pets, and anything combustible. Use the highest quality, purest lamp oil without color or perfumes you can find. This will prevent harmful smoke and particles in the air you are breathing. Check to make sure it is rated as indoor safe. Only use it in a well ventilated area {Which is not a sealed tent environment, sic}, and keep the extinguishers at the ready."
Keep your fire insurance paid up!
