Critical systems are systems that have direct effects on human health and life. Large production systems are an example of the critical system. Safety is a concept that is ubiquitous in our life but has never been clearly defined. A common confusion with safety is that safety is viewed to be the same as reliability. In this paper, we revisit the concept of safety and propose a new approach for design and operation management of critical systems for safety. The new approach puts its foot on the threats to human health and life and an integrated consideration of reliability, robustness and resilience for safety. The new approach for safety is thus called 3R for safety.
