All workers and visitors at LANL are links in a safety and security chain that creates a safe work place. Each person in the chain must work safely and securely, help others work safely and securely, and protect the environment. The safety and security chain starts with you and flows upward to the LANL Director. Before you begin work, find out who your safety-, security- and environment- responsible line manager (RLM) is. It is usually your group line manager.
