There are different types of safety certifications for helmets. Frankly, it can be confusing for the average person investigating inline helmets! To play it safe, look for a helmet that meets the Consumer Products Safety Commission (CPSC) standards, the American Society for Testing and Materials (ASTM) standards, or the America National Standards Institute (ANSI). There is also another certification called the Snell standard, which deals more with multiple-use helmets. A helmet that is certified for both multiple-impact and single-impact use will have a CPSC sticker and an ASTM sticker that is labeled “1492”. These numbers indicate the certification for multiple impact sports, such as skateboarding or aggressive inline skating. Most helmets manufactured since 2000 will have stickers in them indicating that the helmets do, indeed, meet certain safety requirements. If you have been using a helmet for several years or you are acquiring a used helmet, make sure the helmet was manufactured after 1999, just to be on the safe side. On a similar note, laws vary from state to state and city to city on helmet use and helmet standards. For example, a person from California must use a CPSC certified helmet for inline skating. When in doubt, checking with the Bicycle Helmet Safety Institute at www.bhsi.org is recommended because the organization keeps updated information on helmet standards and helmet laws available to the public.
