Which of the following is a recommended distance to keep a heat source from at-home oxygen treatment?

The recommended distance to keep a heat source from at-home oxygen treatment is 5 feet. This guideline is established to ensure safety, as oxygen can greatly enhance combustion. When a heat source, such as a space heater or an open flame, is too close to oxygen equipment, there is a significant risk of fire due to the increased flammability of materials in the presence of high concentrations of oxygen. Maintaining a distance of at least 5 feet acts as a crucial precaution to minimize the chances of ignition and protect individuals using supplemental oxygen from potential hazards. This safety measure is vital in preventing incidents that could lead to serious injuries or property damage.
