Can Propane Grills Explode

Is There a Risk of Explosion with Propane Grills? Hosting a barbecue in your backyard gathers colleagues, family members, friends, and romantic partners for meaningful moments. Grills have the capability to cook food using wood, charcoal, or propane gas. Over time, propane grills have become a favorite option for various users. They offer the convenience of easy ignition and no need to dispose of leftover charcoal.

Unlike charcoal grills, propane grills use flammable gas. This has led to several people expressing concerns about the safety of using one. We will dive deeper into the topic of can propane grills explode in this article.

The Safety Of Propane Grills

Both indoors and outdoors, propane grills are safe to use. You may not have to buy a carbon monoxide monitor or a vent if you use a propane grill outside. You just need to heat your food item on the grill and get it ready.

You should also maintain your propane grill properly by inspecting it before and after every use for possible leaks or damage. When not using the grill right away, close the valve on the propane tank; otherwise, check the burner’s valve for leaks. 

Explosion Of A Propane Tank On A Gas Grill

You can use a gas grill propane tank to power your grill without worrying about it exploding if you use it correctly. 

An explosion of a propane tank can be caused by a variety of factors. The length of time you spend grilling is not likely to cause propane gas explosions. Ensure that the hose, propane tank, and any other part of the grill are in good condition before, during, and after using it. It’s flammable and liquefies under pressure, but propane tanks aren’t made from plastic material. 

There are many types of propane tanks, including stainless steel and metals. As a result, they are durable and hardy containers with safety features built-in. Tanks of this type may also have walls ranging from ¼ to ⅜ inch thick. There are several ways a propane-based accident can occur, so we’ll run through them.

All propane tanks have a few numbers imprinted on the handle, the most frequent of which are the WC (water capacity) and TW (tank weight when empty). When empty, most propane tanks for grilling weigh roughly 17 pounds and store around a pound of propane.

Weigh the tank and deduct the tare weight to determine how many pounds of propane are left. For example, if you weigh the tank and find that it weighs 27 pounds (12 kilograms) overall with a tare weight of 17 pounds (8 kilograms), you’ll find that you have 10 pounds (4.5 kilograms) of propane left — around half a tank.

Cooking Time

When estimating how long one gas tank will last, a little arithmetic goes a long way. To begin, remember that one gallon of propane (3.8 liters) produces around 92,000 BTUs. Divide that quantity by your grill’s BTUH (BTUs per hour) rating. This gives you the number of hours it will take to utilize one gallon of propane at the grill’s maximum temperature.

Finally, divide the number of hours by the tank’s capacity in gallons. 4.7 gallons (17.8 liters) of propane is held in a full 20-pound (9-kilogram) propane tank. If your grill has a 32,000 BTUH output, you’ll receive about 13.5 hours of cooking time on a regular propane tank if you cook at maximum heat. If you just use two of the four burners, you should expect the cooking time to be doubled.

The Benefits Of Putting Your Propane Tank Underground

  • You are in a condition that is prone to harsh weather, particularly deep cold. When the tank is underground, it is surrounded by earth, which helps to maintain a consistent temperature.
  • When it comes to potential damages such as propane leaks, underground propane tanks are safer because a gas leak would be contained better by the earth. Propane is non-toxic to both people and the environment, although flammable.
  • You’d want it to be hidden. You can use landscaping to surround an underground tank’s top, which houses the gauges and other controls. An underground tank may sometimes increase the value of a home.

Leaks that lead to Propane Grills Explode

The propane tank is usually left open, and the gas escapes from the tank and builds up in confined spaces. Light a match, and you could trigger an explosion from a propane tank. 

BLEVE (Boiling Liquid Expanding Vapor Explosion)

BLEVE occurs when the propane tank’s pressure exceeds what can be safely vented. An explosion can occur when the tank ruptures. Despite the relative safety of propane grills, their most common cause of the explosion has little to do with the gas tank. Obviously, propane leaks are the most common cause, but there is much more to learn about the causes of propane grill explosions and what to do if it happens. 

The Safety Of Propane Grills Indoors

You have to take certain steps to make this happen. You should ensure that the propane grill is not close to flammable materials and that the connectors are tight. Install a carbon monoxide detector in your home if you have a kitchen or cubicle that does not have proper ventilation.

If you think about the measures you’d need to take to burn propane inside, you’ll realize that it’s better to use propane outdoors. In comparison with wood, charcoal, and kerosene, propane is inexpensive and burns cleanly.

Propane Grill Distance From House

Grills cook with heat, so it’s best to mount them some distance away from nearby structures, such as houses, sheds, garages, and decks. You can also check your local fire code for more information if you’re not sure of the safe distance. 

Several reasons exist for mounting your grill away from your home. To ventilate properly, your grill needs adequate air space. You can expect high levels of carbon monoxide, gas, or smoke under poor ventilation.

Propane grills shouldn’t be placed by the side of your house, as the heat can severely damage the siding. Although you can use a propane grill in your backyard, if you want to be extra cautious, try mounting it at a distance of at least 10 feet from your house. 

Place other grills far away from your house in addition to the propane grill to ensure their safety. It won’t damage or reduce the value of your house if its heat or smoke comes from these cookers.
