 Safety-Critical Systems Club 
 For Everyone Working in Systems Safety

The SCSC is the UK's professional network for sharing knowledge about system safety.  It brings together engineers and specialists from a range of disciplines and industries working in system safety, academics researching the arena of system safety, providers of the tools and services that are needed to develop the systems, and the regulators who oversee safety.

The SCSC provides seminars, workshops and tutorials throughout the year, with a three-day annual Safety-Critical Systems Symposium in February.
