Meaningful Change to Protect Children: Reese’s Law
Thousands of battery ingestion accidents send children to the ER each year. One of these incidents claimed the life of 18-month-old Reese Hamsmith, and through her mother’s tireless advocacy, Reese’s Law was passed, requiring UL 4200A compliance in products containing button or coin cell batteries. Together with parents, industry experts, safety advocates, and government, we worked to ensure fewer families experience similar heartbreak.
Ushering in Safer E-mobility Laws & Standards
What started as an effort to reduce injuries and deaths from e-mobility devices in New York City is now a budding story of e-mobility safety throughout the United States. Learn about the hazards of e-mobility devices like electric bikes and scooters, the incidents affecting your community, and how action in New York City is spurring safety reform across the country.
Detection is Prevention Against Carbon Monoxide Poisoning
Daryl and Shirley Jenkins checked into their hotel room, believing it was safe. Tragically, this assumption was incorrect, as the hotel lacked a carbon monoxide detector. Just seven weeks later 11-year-old Jeffrey Williams also lost his life to CO poisoning – in the same room.
Motivated to protect more families from this tragic ending, Jenkin’s surviving daughter, Kris, started the Jenkins Foundation to increase awareness of carbon monoxide poisoning. Working together with ULSE, Kris helped update UL 2034, a safety standard for CO alarms, to support small businesses in stopping similar tragedies.
Help Us Make the World Safer
The best standards result from diverse voices and deep collaboration. Be part of the process by reviewing options for participation to inform the next generation of standards.
Technical Committees
Each TC is a diverse group of experts representing a broad range of perspectives and interests, including consumers, manufacturers, regulators, supply chain professionals, and more.
As a TC member, you will review proposals for new or revised standards and work collaboratively to achieve consensus through balloting in our transparent process.
Stakeholders
Stakeholders can submit, review, and comment on proposals for new standards or revisions to existing standards. While these individuals cannot vote, the TC considers their input during the standards voting process. Since standards affect everyone, all are welcome to participate as stakeholders. Register online through our Collaborative Standards Development System, CSDS.
