Caution--Warning Ahead!  

Safety and warning notices form the most important elements of user information wherever safety and [product liability are concerned. A carefully thought out and systematic process is required in developing safety-relevant information, in order to increase the completeness and comprehensibility of product safety. This will also disarm any suspicion of gross negligence in internal documentation in case of missing safety notices and it will ensure traceability.
