What Are The Risks Of Using Propane Heaters Indoors?

The primary dangers of utilizing these heaters are:

  • fire; and
  • CO (carbon monoxide) poisoning.


Propane is quite flammable. If your propane tank leaks, there is a huge chance of a fire breaking out in your home.

Because propane is heavier than air, it tends to sink to the ground and accumulate in the cracks and crevices of your home, where it can be ignited by flames, sparks, or even static electricity.

CO (Carbon Monoxide) Poisoning

The most serious risk of utilizing a buddy heater in an enclosed environment, such as your RV, is carbon monoxide poisoning.

The combustion of propane, like that of natural gas, produces carbon monoxide. Because carbon monoxide is colorless and odorless, it might be difficult to detect until it is too late. Effective carbon monoxide detectors are necessary for any home, especially one heated with propane. 

Safety Practices To Do When Using Buddy Heater In Your RV

Although you can use buddy heaters in campers, it won't hurt to follow these safety practices to ensure that there won't be any damage: 

  • Use a commercial carbon monoxide detector at all times.
  • Ensure that the heater is intended for indoor use.
  • Understand the symptoms of carbon monoxide poisoning and the levels at which they occur.
  • Maintain a cracked window vent by the owner's handbook.
  • Never sleep with a buddy heater turned on.
  • If you are sleepy or experiencing other symptoms, move out of that area and get some fresh air to see if you feel better. Do not use the heater any longer.
  • Regularly inspect your heater for leaks.

What Are The Symptoms Of Carbon Monoxide Poisoning?

Dizziness, headache, weakness, chest discomfort, upset stomach, vomiting, and confusion are the most typical symptoms of carbon monoxide poisoning.

CO symptoms are frequently described as flu-like, and inhaling a large amount can cause you to faint or kill you. CO poisoning can kill people who are sleeping or drinking before they show symptoms.

Benefits Of Using Carbon Monoxide Detectors

Carbon monoxide detectors alert you to rising carbon monoxide contents in a building or residence. The alarm alerts you when one of your appliances isn't working properly and can alert anyone in the building before it's too late.

A carbon monoxide monitoring system can also protect those who are unable to respond to alerts, such as pets, the elderly, youngsters, the disabled, and others.

How To Properly Handle Propane?

Most, if not all, buddy heaters run on propane, and this type of duel can be quite dangerous. So here are some guidelines on how to handle propane properly: 

Never keep propane tanks indoors

If a canister has even a minor leak, keeping propane inside is dangerous. Keep your propane tank outside and away from any nearby power lines.

Keep embers, sparks, and open flames away from propane

Propane is highly flammable. It's common sense to keep any fire source as far away from your propane canisters as possible.

If you smell gas, turn off the valve and contact a professional

Seal the valve as much as you can if you suspect your propane canister is leaking. Then remove everyone from the canister and contact a specialist to inspect it. They will be able to conduct any necessary repairs effectively.

Propane canisters should be stored upright

A propane tank turned sideways puts the valve at risk of harm. This can result in leaks, fires, or even an explosion.

Fill canisters to no more than 80% capacity

Propane expands and contracts in response to temperature changes. By leaving 20% of your tank's capacity accessible, you allow it to readily manage large temperature changes.
