Flame King Recalls Hog 100-Pound Propane Cylinders Due to Fire Hazard

What was recalled

The U.S. Consumer Product Safety Commission (CPSC) has announced a significant recall involving propane cylinders manufactured by Flame King. Specifically, this action targets the "Hog" 100-pound propane cylinders. If you have purchased or received one of these units, it is important to understand exactly which products are affected so you can take the appropriate safety steps immediately. This recall was officially announced on March 24, 2021, and it focuses on a specific subset of inventory that may contain a manufacturing defect capable of leading to dangerous gas leaks.

The recalled items are distinct in their appearance and identification marks. These are white propane cylinders equipped with built-in wheels for easier mobility around your property or worksite. To help you determine if your unit is part of this recall, you need to look for specific physical identifiers. First, check the collar of the cylinder for a stamped serial number. The recall applies only to units with serial numbers ranging from 000001 through 002800. If your serial number falls outside this range, it is not part of this specific recall action.

In addition to the serial number on the unit itself, you can verify the product by checking the original packaging. The boxes for these recalled cylinders are printed with a Universal Product Code (UPC) of 850015730016 and a Stock Keeping Unit (SKU) of YSN100HOG. These codes should be clearly visible on the exterior of the box where the product was originally sold. Furthermore, each cylinder features a sticker with a warning label that instructs users not to fill the unit unless it is standing upright. While this warning is present on the recalled units, the presence of the sticker alone does not guarantee safety if the underlying manufacturing defect exists.

It is crucial to note that this recall covers a finite number of units defined by the serial number range mentioned above. The defect involves the construction of the handle relative to the weld on the side of the cylinder. In these specific units, the handle was manufactured below the weld, which creates a potential pathway for propane gas to leak. While the recall does not specify exactly where these cylinders were sold geographically, they are distributed consumer products that may be found in home garages, workshops, or commercial settings across the United States. If you possess a white Hog 100-pound propane cylinder with built-in wheels, and its serial number is between 000001 and 002800, it falls under this safety alert regardless of when or where it was purchased.

The hazard, explained

When we talk about propane cylinders, we are dealing with highly pressurized fuel that is essential for everything from backyard grilling to industrial heating. The specific issue with the recalled Flame King Hog 100-Pound Propane Cylinders centers on a structural flaw in how the handle is attached to the tank itself. According to the Consumer Product Safety Commission (CPSC), these cylinders were manufactured with a handle positioned below the weld on the side of the unit. In a well-designed tank, the connection points for handles and valves must be reinforced to withstand immense internal pressure and external physical stress. When a handle is mounted in a way that compromises or sits adjacent to a critical weld line without adequate reinforcement, it creates a weak point in the cylinder’s integrity.

Propane is stored under high pressure to keep it in liquid form. Over time, or even immediately if the structural weakness is significant, this flaw can allow propane gas to escape. This is not a slow, visible drip like water from a leaky faucet; rather, it is often an invisible leak of gas that can build up unnoticed. Because propane is heavier than air, it tends to sink and pool in low-lying areas, such as basements, garages, or the ground around where the cylinder is stored. This accumulation creates a volatile cloud of fuel that does not require a spark from an electrical switch or a lighter to ignite. A static electricity discharge, a pilot light from a nearby water heater, or even a simple friction spark can trigger a fire or explosion.

The danger here is twofold. First, the immediate risk is fire. If the leaking gas encounters an ignition source, it can cause a flash fire that can spread rapidly to nearby combustible materials. Second, there is the risk of asphyxiation in enclosed spaces. While propane itself is not toxic, it displaces oxygen. In a poorly ventilated area where a large cylinder is leaking, the concentration of oxygen can drop to dangerous levels. Although no incidents or injuries have been reported with this specific batch yet, the potential for harm is severe because the hazard is hidden. You cannot see gas escaping until it is too late, which is why identifying and removing these cylinders immediately is critical. The presence of a sticker warning users not to fill the unit unless it is standing up highlights that the tank’s orientation matters for safety, but the underlying manufacturing defect regarding the handle and weld remains the primary cause for concern regardless of how the cylinder is positioned.

Understanding this mechanism helps clarify why a refund or replacement is the only safe remedy. You cannot simply patch a welded structural flaw on a high-pressure vessel. The integrity of the steel tank has been compromised at a critical stress point, and no amount of careful handling can guarantee that the leak will not occur during transport, filling, or normal use. Therefore, recognizing this physical defect is the first step in protecting your home and family from a preventable disaster.

Who is most at risk

When we look at the specific details of this Flame King recall, the primary group at risk includes anyone who owns or operates a Hog 100-pound propane cylinder, particularly those using them for outdoor grilling, heating, or commercial food service. Because these are large, high-capacity tanks, they are typically found in settings where significant heat is generated over extended periods. The individuals most vulnerable to the consequences of a propane leak are not just the owners, but anyone sharing that space with the cylinder—family members, friends, employees, or customers who may be unaware of the defect.

The nature of propane gas itself creates a unique set of risks for different demographics. Propane is heavier than air, meaning it does not simply dissipate upward like smoke from a fire. Instead, it sinks and pools in low-lying areas, such as the ground around a grill or beneath a deck. This physical property makes children particularly vulnerable. If a small child were to crawl near a leaking cylinder, they would be breathing at the level where the gas concentration is highest. Young children have smaller lung capacities and higher respiratory rates than adults, which means they can inhale a dangerous dose of gas more quickly than an adult standing nearby. Furthermore, their curiosity might lead them to investigate the source of a smell or even tamper with the valve, potentially turning a leak into a spark.

Elderly individuals or those with respiratory conditions like asthma, COPD, or heart disease also face heightened risks. Even without ignition, prolonged exposure to propane fumes can cause dizziness, headaches, nausea, and confusion. For older adults, these symptoms can be mistaken for other health issues, delaying proper ventilation or medical attention. Additionally, if a leak occurs in an enclosed or semi-enclosed space like a patio cover or garage, the accumulation of gas can reach explosive limits before anyone realizes there is a problem. The elderly may have slower reaction times to detect the initial signs of trouble, such as the faint odorant added to propane, or they may live alone, increasing the danger if an incident occurs without immediate help.

It is also important to consider the physical handling of these large units. The recalled cylinders are equipped with wheels and handles, but the defect involves a specific manufacturing flaw where the handle is positioned below the weld on the side. This design could compromise the structural integrity during transport or use. Individuals who frequently move these tanks—such as restaurant staff, event planners, or homeowners who store them in garages—are at risk not just from gas leaks, but from potential physical injury if the cylinder fails under stress. While no incidents have been reported yet, the potential for a sudden release of high-pressure gas combined with the weight of the unit creates a scenario where quick thinking and clear communication are essential for safety.

How to tell if you have the recalled item

Before you take any action or contact the manufacturer, the most critical step is confirming whether your specific propane cylinder is part of this recall. Because Flame King produces various models, it is essential to verify that your unit matches the exact specifications outlined in the Consumer Product Safety Commission (CPSC) notice. The recall specifically targets the "Hog 100-Pound Propane Cylinders." If you have a different capacity, such as a 20-pound or 30-pound tank, or a model from a different brand line, this particular safety alert does not apply to your equipment. However, if you do own a large, white, wheeled propane tank, you need to look for several distinct identifiers to be certain.

The physical appearance of the cylinder is the first clue. The recalled units are painted white and feature built-in wheels, designed for easier mobility around patios, gardens, or industrial sites. While color alone isn’t proof, it helps narrow down your search if you have multiple tanks. The most definitive way to identify a recalled unit is by checking the serial number stamped directly onto the collar of the tank. You must locate the series of numbers stamped into the metal near the valve assembly. If your serial number falls between 000001 and 002800, inclusive, your cylinder is part of this recall. This range covers units manufactured during the specific window identified by the company, so even if two tanks look identical, only those within this numerical sequence are subject to the safety warning.

In addition to the stamped serial number, you should check the packaging or any labels still attached to the tank for barcodes and stock keeping units. The recalled cylinders carry the Universal Product Code (UPC) 850015730016. You will also find the SKU code "YSN100HOG" printed on the box. If you have discarded the original packaging, look for a sticker on the cylinder itself that contains a specific warning: "Do not fill unless the unit is standing up." This label is a key identifier for this particular batch of Hog cylinders. By cross-referencing the serial number range with the UPC and SKU codes, you can confidently determine if your propane tank is involved in this fire hazard recall.

If you are unsure after checking these details, or if you cannot find clear markings due to wear and tear, it is always safer to assume the tank might be included and proceed with caution. Do not attempt to use, refill, or transport the cylinder until you have verified its status through the contact methods provided by Flame King. Taking a few minutes to inspect the collar and labels now can prevent potential confusion later and ensure your safety.

What can happen if you ignore it

When a recall notice arrives in the mail or appears on your screen, it is natural to feel overwhelmed. The immediate reaction for many homeowners and contractors is to assume that because a product has worked perfectly fine for weeks or even months, it must be safe to keep using it until it runs out of fuel. However, with the Flame King Hog 100-pound propane cylinders, this assumption is dangerously incorrect. Ignoring this recall does not merely delay a refund; it exposes you and your property to a specific, tangible fire hazard that stems directly from the manufacturing defect.

The core issue lies in the physical construction of the cylinder. These units were manufactured with a handle positioned below the weld on the side of the tank. This design flaw creates a structural vulnerability that standard usage can easily exploit. Over time, the weight of the full cylinder—propane is heavy, and 100 pounds is no small amount—combined with the stress of moving, tilting, or simply resting against uneven surfaces, can compromise that weld. When the weld fails or is stressed beyond its limit, it creates a pathway for propane gas to escape. This is not a slow, gradual leak that you might smell immediately in a well-ventilated area; it is a potential breach in the containment system of a highly flammable substance.

Propane gas is heavier than air and colorless. If a leak develops from this faulty weld, the gas can pool in low-lying areas, such as the space between your tank and the ground, or inside enclosed storage sheds and garages. The danger escalates rapidly when that accumulated gas encounters an ignition source. In a typical outdoor setting, this could be a pilot light on a nearby grill, the spark from a starting engine, static electricity, or even a cigarette butt. The result of such an encounter is not just a minor inconvenience; it is an immediate and violent fire or explosion. Because the tank itself contains under pressure, a breach can lead to a BLEVE (Boiling Liquid Expanding Vapor Explosion), which projects shrapnel and intense heat over a wide area.

While the CPSC report confirms that no incidents or injuries have been reported to date with this specific batch of cylinders, this absence of data is not evidence of safety. It is simply a reflection of luck rather than design. The hazard exists in the potential for leakage, not just in the occurrence of fire. By continuing to use these cylinders, you are essentially carrying a ticking time bomb that relies on perfect structural integrity every single day. You are gambling with your home, your family’s safety, and your neighbors’ property against a defect that could have been eliminated at the factory. The risk is not theoretical; it is mechanical and inevitable given enough stress cycles on the compromised weld.

Furthermore, ignoring the recall means you forfeit the remedy offered by the manufacturer. Flame King has committed to providing a full refund or a free replacement cylinder for this defect. By holding onto the defective unit, you are not only risking your safety but also losing the financial protection that the company is willing to provide. The cost of the risk far outweighs the effort of contacting their customer service line. When it comes to high-pressure fuel containers, "if it ain't broke" is a dangerous mindset when the break is hidden inside a weld you cannot see. Do not wait for the smell of gas or the sight of a flame to validate the recall notice. Act now to eliminate the hazard entirely.

Staying safe: broader tips

While this specific recall addresses a manufacturing defect in a particular batch of propane cylinders, the underlying principle applies to all users of pressurized gas appliances. Propane is an invisible, highly flammable fuel that requires respect and routine maintenance to ensure it remains safe in your home or workshop. The most critical step in preventing accidents with any LPG (liquefied petroleum gas) equipment is regular inspection. Before you connect a cylinder to a grill, heater, or torch, always check the valve for damage and ensure the connection points are clean and undamaged. Over time, rubber gaskets can dry out or crack, creating invisible pathways for gas to escape. Replacing these small, inexpensive components annually is far cheaper than dealing with the consequences of a leak.

Airflow is your best friend when dealing with propane. Never use propane-powered devices in enclosed spaces such as garages, tents, basements, or inside vehicles unless they are specifically designed for indoor use and properly vented. Propane is heavier than air, meaning any leaked gas will settle low to the ground rather than dissipating into the ceiling. This pooling effect creates a concentrated pocket of fuel that can be ignited by a single spark from a light switch, a pilot light, or even static electricity. Always ensure you are operating these cylinders in well-ventilated outdoor areas, keeping them upright to prevent liquid propane from escaping through the valve, which can cause rapid expansion and freezing injuries.

Storage practices play a significant role in long-term safety. When not in use, keep your propane cylinders outdoors, away from direct sunlight and heat sources like furnaces or water heaters. Extreme heat increases the pressure inside the tank, potentially triggering the relief valve to vent gas unnecessarily. Furthermore, ensure that all connections are tightly secured but avoid overtightening, which can strip threads and compromise the seal. If you ever smell a rotten egg odor—propane is naturally odorless, but an odorant is added for detection—evacuate the area immediately. Do not attempt to locate the leak with a flame, and do not operate any electrical switches or phones in the vicinity.

Finally, stay proactive about product safety by registering your appliances upon purchase. Manufacturers use these registrations to notify you directly if a defect is discovered in your specific model or batch. Additionally, consider installing carbon monoxide detectors in areas where fuel-burning appliances are used nearby, as incomplete combustion can produce this deadly, odorless gas. Regularly reviewing official recall databases from the Consumer Product Safety Commission (CPSC) ensures you are aware of any widespread safety issues affecting the equipment you rely on daily.
