October 20, 2026 — An incident report details a concerning safety issue involving Dewalt DCF 961B and other high-power impact gun models, where debris was allegedly ejected from open ventilation ports during normal operation, posing an eye injury risk due to an alleged design defect.
Product Details
Incident Overview
The incident report, filed on September 27, 2026, describes multiple occasions where a Dewalt DCF 961 impact gun ejected debris from its open ventilation ports at the user’s face and eyes during normal operation. The user noted that the product’s manual advises blowing air into the fan port weekly to reduce hazardous debris and recommends wearing Z87.1 safety glasses due to eye injury risk. However, the report highlights a critical distinction: the motor fan, during normal use, actively forces air and, consequently, debris out of these same open ventilation ports directly towards the user.
The consumer alleges that Dewalt is aware of the debris hazard, as indicated in the manual, but failed to warn users about debris ejection specifically during normal operation. The report claims that the DCF 961, DCF 964, and the compact atomic series — described as Dewalt’s highest power models — have had their ventilation port guards removed by designers, leaving them open. In contrast, all lower-power Dewalt impact models reportedly retain these protective ventilation port guards. The removal of these guards without a mesh or screen in place is cited as a factory design defect that can injure users during the tool’s normal, intended use.
Safety Concerns
The reported incident raises several serious safety concerns:
- Immediate Dangers: The primary immediate danger is the forceful ejection of debris into the user’s face and eyes. This can cause severe eye injuries, including corneal abrasions, lacerations, foreign objects embedded in the eye, and potentially permanent vision impairment or blindness. Facial injuries are also possible.
- Long-Term Risks: Repeated exposure to ejected debris, even if minor, can lead to cumulative eye damage, chronic irritation, or the risk of a more severe incident over time.
- Who Might Be Affected: Professional contractors, DIY enthusiasts, and anyone using the specified high-power Dewalt impact gun models (DCF 961B, DCF 961, DCF 964, and compact atomic series) are potentially at risk. The alleged design defect means that even when following general safety advice like wearing safety glasses, users may still be exposed to an unexpected and forceful ejection of debris specifically from the tool’s own exhaust.
- Property Damage Potential: The incident report does not specify any property damage associated with this incident.
- Design Defect Allegation: The core safety concern revolves around the allegation of a design defect where protective guards have been removed from high-power models, despite their presence on lower-power models. If true, this represents a fundamental flaw in product safety engineering, exposing users to known hazards without adequate protection.
- Inadequate Warning: While the manual mentions eye injury risk and cleaning, the incident report suggests a failure to explicitly warn about debris ejection *during normal operation* from the tool’s own ventilation ports, potentially misleading users about the specific nature and source of the hazard.
What Consumers Should Do
If you own a Dewalt DCF 961B, DCF 961, DCF 964, or any model from the compact atomic series, especially if it lacks protective guards over the rear ventilation ports, consider the following actions:
- Immediately Cease Use if Experiencing Ejection: If you have experienced debris ejection from the ventilation ports, stop using the tool immediately.
- Always Wear Certified Eye Protection: Even if the product is alleged to have a design flaw, always wear ANSI Z87.1-compliant safety glasses or goggles when operating power tools. While the incident suggests this may not fully mitigate the specific hazard, it is crucial for overall eye safety.
- Inspect Your Tool: Carefully inspect the rear ventilation ports of your Dewalt impact gun. Note if protective guards, mesh, or screens are present or absent. Compare with images of other Dewalt models if possible.
- Review Your User Manual: Re-read the safety warnings and maintenance instructions in your product’s manual, paying close attention to sections about ventilation and debris.
- Report Incidents: If you have experienced debris ejection or any other safety issue with this product, report it to the U.S. Consumer Product Safety Commission (CPSC) at www.cpsc.gov. This helps safety authorities track incidents and potentially initiate recalls or safety campaigns.
- Contact the Manufacturer: Consider contacting Stanley Black & Decker, Inc. directly to report your concerns and inquire about product safety.
