January 20, 2026 – A distressing incident involving a Ryobi RY421021 cordless leaf blower has been reported, highlighting potential fire risks associated with the product.

Product Details
Incident Overview
On December 30, 2025, an incident report was filed detailing a significant safety concern involving a Ryobi RY421021 cordless leaf blower. According to the report, the leaf blower spontaneously caught fire while it was hanging in the owner’s garage. The incident occurred without warning, as the product was seemingly inactive and stored in its usual location. Spontaneous combustion of an appliance, especially in an enclosed space like a garage, poses severe risks to property and personal safety. The exact cause of the ignition at the time of the report remains unknown, but such incidents often point to potential internal defects, electrical malfunctions, or issues with battery components in cordless devices.
Safety Concerns
The spontaneous combustion of a cordless leaf blower presents a serious array of safety concerns for consumers:
- Immediate Fire Hazard: The primary and most immediate danger is the uncontrolled fire itself. Fires can spread rapidly, especially in a garage where flammable materials such as gasoline, paints, and other chemicals are often stored. This can lead to a quick escalation from a small flame to a major structural fire.
- Smoke Inhalation: Fires produce toxic smoke and fumes, which can cause severe respiratory damage or even be fatal if inhaled, even in small amounts.
- Property Damage: An incident like this has the potential for extensive property damage, ranging from localized charring to the complete destruction of the garage and its contents, potentially extending to the entire home. Vehicles parked in the garage are also at risk.
- Unexpected Nature of the Risk: The most alarming aspect is the spontaneous nature of the fire, occurring while the product was inactive and stored. This indicates a potential risk that is not limited to active use or charging, making it difficult for consumers to anticipate or prevent.
- Battery-Related Risks: As a cordless electric device, the incident strongly suggests a potential issue with the lithium-ion battery pack or its associated circuitry. Lithium-ion batteries, if defective, damaged, or improperly manufactured, can overheat, short-circuit, and enter a state of “thermal runaway,” leading to fire or explosion.
- Who Might Be Affected: Any homeowner who owns or stores this specific model of Ryobi cordless leaf blower, or similar cordless power tools, could be affected. Neighbors and first responders also face risks when a garage fire erupts.
What Consumers Should Do
Given this serious incident, consumers who own a Ryobi RY421021 cordless leaf blower should take immediate action:
- Prioritize Safety: If you witness a product spontaneously igniting, prioritize your safety and the safety of those around you. Evacuate the area immediately and call emergency services (e.g., 911 in the U.S.). Do not attempt to extinguish electrical or battery fires yourself unless you are specifically trained and equipped to do so, as they can be difficult to put out and may reignite.
- Identify Your Product: Check if you own the Ryobi RY421021 model leaf blower. The model number is typically found on a label on the tool itself, often near the battery compartment or on the motor housing.
- Safe Storage Practices: If you own this model, consider storing it in a detached shed or an area away from highly flammable materials and living spaces. Ensure batteries are stored in a cool, dry place, away from direct sunlight, heat sources, and combustibles. Avoid storing batteries where they could be easily damaged.
- Inspect for Damage: Regularly inspect your leaf blower and its battery pack for any signs of damage, such as cracks, swelling, discoloration, unusual odors, or signs of overheating. If you notice any such issues, immediately discontinue use and proper disposal of the battery.
- Charge Safely: Always use the manufacturer-recommended charger for your battery. Charge batteries on a non-combustible surface, away from flammable materials, and in a well-ventilated area. Avoid leaving batteries unattended while charging, especially overnight.
- Report Incidents: If you experience any issues with your Ryobi RY421021 leaf blower, particularly overheating, smoking, or fire, report it immediately to the U.S. Consumer Product Safety Commission (CPSC) at www.cpsc.gov.
- Contact the Manufacturer: Reach out to One World Technologies, Inc. (Ryobi’s manufacturer) to report the incident and inquire about safety guidelines or potential recalls related to this model.
