Risks of Propane Garage Heaters

  1. Carbon Monoxide (CO) production

CO is a natural byproduct of the combustion of propane gas. This tasteless and odorless gas affects hemoglobin molecules in human blood and reduces the concentration of oxygen.

  1. Propane Gas Leak

When an appliance valve or gas line is left open unconsciously, leakage of propane gas occurs which may cause a serious accident.

  1. Flammable Vapor Ignition

If the propane heater comes in contact with the vapor of flammable products such as gasoline, kerosene, paint thinner, and solvents the possibility of occurring ignition increases at a high rate.

  1. Odor Loss

Propane has a strong odor that lets you quickly discover a leak with a simple sniff. But, sometimes propane may lose its odor because of the inclusion of air, water, or rust in a propane tank or cylinder.If odor loss occurs it will be difficult for you to discover the leakage of propane.

  1. The risk with Pilot light

The pilot light is a small, constantly burning flame that remains inside the propane garage heater which ignites the main burner.  Sometimes pilot light goes out frequently or it becomes hard to ignite the pilot light which is a sign of a problem with your propane garage heater or propane tank.

Propane Garage Heater Safety Guide

Facts about CO

After turning on heater we generally close the doors and windows properly to prevent the loss of heat and the entrance of cold from outside. But this is a great mistake that can bring serious problems when you are using a propane heater.

It is true that you cannot prevent the generation of CO from your propane garage heater but it is not risky if there is enough ventilation. Risk arises CO stacks in an area due to lack of ventilation.

You may think that if you keep vent in your garage it will cause heat loss and allow the flow of cold air inside your garage. But, don’t worry dear. Propane garage heaters generate enough heat that a small amount of heat loss and the entrance of cold air will not be felt.

Since CO is a tasteless, colorless and odorless gas it is a common question that how will you suspect the presence of CO.

A CO detector can help you to detect the presence of CO gas. There is a sensor in this detector that senses the presence of CO and alerts you with an alarm.

If you notice excessive moisture inside your windows and smell burning odor then immediately check the exhaust vents and your propane heater because there is pretty much possibility of such a situation occurs due to CO poisoning.

Moreover, if the propane heater is working and you suddenly feel a headache, dizziness, shortness of breath and nausea the reason behind is the presence of CO. If you feel such discomfort, immediately open windows, turn off the heater and if the case is very serious call 911.

To reduce the risk of CO poisoning check the propane garage heater and the exhaust vents annually with the help of a professional gas service technician.
