The voluntary standard for table saws is UL 987 Stationary and Fixed Electric Tools. In November 2007, a seventh edition of UL 987 was published with requirements for a new modular blade guard that is designed to be adjustable for more cuts, to provide clear visibility of the cutting edge, and to be easily installed and removed without the use of tools. The majority of table saws sold in the United States since 2009 meet the UL 987 seventh edition requirements of the modular blade guard.
In August 2011, the US Consumer Product Safety Commission (CPSC) published an ANPR for table saws.
Currently, it is unknown if and how consumers are using the modular blade guard. Since the usage patterns are directly linked to safety of the user, data is needed to understand the usage of the modular blade guard to determine how effective the design will be in preventing future injuries.
