Recognizing that technology is not perfect, the U.S. Consumer Product Safety Commission (CPSC) provides safety tips and product information for consumers. From this website, visitors can learn about product recalls and safety news, report an unsafe product, sign up for free email announcements about new recalls and safety information, or become part of the Neighborhood Safety Network, which is designed to "help all Americans become aware of lifesaving safety information." CPSC publications are also available online, addressing topics such as clothing, electrical, and holiday safety. A few publications are available in Spanish, Chinese, Korean, Tagalog, and Portuguese. CPSC also conducts and sponsors research projects "in furtherance of its activities to improve product safety and reduce or eliminate potential hazards associated with consumer products." The findings from such projects may inform voluntary and mandatory product safety standards and assess the potential for emerging technologies to enhance consumer product safety. Research Reports on topics such as the Detection of Abnormal Operating Conditions in Electric Clothes Dryers and A Review of the Sound Effectiveness of Residential Smoke Alarms are posted online.
