Incident Overview

On March 4, 2026, a consumer was using a Ryobi 4-Gallon Backpack Sprayer (model EU21091N280171) in accordance with the manufacturer's specifications. During normal operation, the pressurized fluid line snapped at the connection point, causing a sudden and forceful expulsion of a toxic herbicide containing 2,4-D. The consumer sustained direct chemical exposure, resulting in skin irritation that required first aid administered by a non-medical professional.

The failure was catastrophic: the line detached completely, releasing the contents under high pressure. The reporter noted that heavy-duty workwear was completely destroyed by the chemical exposure. The incident underscores a critical flaw in the pressurized vessel's connection point, which failed despite the product being used as intended. The product was purchased at Home Depot.

Safety Concerns

Immediate Dangers: The sudden rupture of a pressurized line containing toxic chemicals like 2,4-D can cause direct skin contact, eye exposure, or inhalation. In this case, the consumer suffered skin irritation requiring first aid. High-pressure release also poses a risk of chemical injection injuries, which can be severe.

Long-Term Risks: Repeated or prolonged exposure to 2,4-D has been associated with potential health effects, including skin sensitization and, in some studies, links to more serious conditions. Even a single high-concentration exposure may require medical monitoring.

Who Might Be Affected: The primary user is at immediate risk, but bystanders—including children or pets—could also be exposed to the spray or contaminated surfaces. The backpack design means the user's back and neck are particularly vulnerable.

Warning Signs: While no warning signs were reported in this incident, consumers should watch for any bulging, cracking, or leaking around hose connections, as these may indicate impending failure. Unusual vibrations or pressure fluctuations during use could also signal a defect.

What Our Clients Say

What Consumers Should Do

Stop Using Immediately: If you own a Ryobi 4-Gallon Backpack Sprayer, discontinue use until the manufacturer provides guidance. Do not attempt to pressurize or operate the unit.

Do Not Attempt Repairs: Do not try to repair the hose connection or replace parts yourself. Tampering could lead to further failure or void any potential recall remedies.

Preserve the Product: Keep the sprayer in its current condition, including any damaged components and the remaining chemical mixture. The product may be needed for inspection by the manufacturer or for legal purposes.

Document the Incident: Take photographs of the failed connection point, any damage to clothing, and any visible skin irritation. Write down the date, time, and details of the incident.

Seek Medical Attention: If you experienced any skin irritation, eye exposure, or breathing difficulties, consult a healthcare professional. Even if symptoms seem mild, chemical exposure can have delayed effects.

Report to the CPSC: File a report at SaferProducts.gov (Report ID 5948576) to help regulators track the defect and consider a recall. Also check CPSC.gov for any official recall announcements.
