Propane Heater Safety for Businesses: How to Prevent Fires and Protect Customers

As cooler weather sets in, many restaurants, bars, and event venues rely on propane heaters and fire pits to keep outdoor areas comfortable for patrons. While these units are popular and effective, they also pose real safety risks if not properly maintained or used.


At Risk Assured, we help businesses reduce liability and maintain safe operations through proactive safety practices. In this guide, you’ll learn how to operate, store, and inspect propane heaters the right way—so you can keep guests warm without compromising safety.

Why Propane Heater Safety Is Essential

Propane is a highly flammable gas that is heavier than air. Instead of rising and dissipating, it pools near the ground—creating a serious ignition hazard if leaked. When combined with an open flame and busy commercial environments, the risk of fire, explosion, or carbon monoxide poisoning increases significantly.


Step 1: Train Employees Before Use

Anyone responsible for setting up or using a propane heater should be fully trained in:

  • Manufacturer’s operating instructions

  • Connection procedures

  • Proper clearance zones

  • Maintenance and inspection routines

  • Emergency shutdown protocols

Training ensures safe operation and reduces the risk of accidents that can result in injury, lawsuits, or property damage.


Step 2: Inspect Before Every Use

Before igniting any propane heater:

  • Check for visible damage to the tank, hoses, and ignition system

  • Ensure hoses are not cracked or leaking

  • Confirm all gas connections are secure

  • Conduct a leak test using soapy water—never use an open flame

  • Maintain proper clearances:

    • At least 3 feet from flammable objects

    • 10 feet from combustible building surfaces

  • Ensure the unit is placed on a flat, stable surface

  • Make sure the area is well-ventilated (never operate indoors)

If a leak is detected or a component is damaged, do not use the unit until it’s repaired by a qualified technician.


Step 3: Know When and Where Not to Use a Propane Heater

Certain conditions and environments can significantly increase risk:

  • Never use propane heaters indoors or in non-ventilated areas. These units produce carbon monoxide, which can be deadly without proper airflow.

  • Avoid operating heaters in windy conditions, as wind can tip units over or extinguish the flame.

  • Never move a heater while it’s lit. Always shut off the flame and close the valve before repositioning.


Step 4: Store Propane Tanks and Heaters Safely

Improper storage is one of the most common sources of fire hazards with propane-powered appliances.

Propane Storage Best Practices:

  • Always shut off the valve before storing

  • Store tanks upright to prevent liquid propane from contacting the relief valve

  • Keep away from heat sources, ignition sources, or direct sunlight

  • Never store propane tanks indoors or in enclosed spaces

  • Use lockable, open-air storage cages for multiple tanks, similar to commercial propane exchanges

  • Never tamper with or modify the tank’s safety valves


Step 5: Maintain and Monitor Equipment Regularly

Routine inspections can catch early warning signs of failure. Key areas to inspect:

  • Burner tubes and vents (check for clogs or insect nests)

  • Ignition systems

  • Regulators, hoses, and seals

  • General stability of the unit

Heaters should undergo annual inspections by a qualified technician and be logged in a maintenance record.


Quick Safety Checklist for Propane Heater Use

  • Use only in well-ventilated outdoor spaces

  • Maintain required clearances from combustibles

  • Check hoses, connections, and valves before each use

  • Shut off heaters before moving or refueling

  • Store tanks properly and never indoors

  • Provide accessible fire extinguishers near each heater

  • Never use a damaged or malfunctioning unit


Final Thoughts: Keep Warm Without Compromising Safety

Propane heaters are a great way to extend outdoor operations into cooler months—but they must be used with caution. Fires and carbon monoxide poisoning are entirely preventable with the right training, inspections, and safety protocols.
