Safety research aims to create safer products, systems, and practices by incorporating scientific, engineering, and behavioral insights. Ultimately, it seeks to enhance public safety, reduce economic losses, and improve overall quality of life by ensuring that both individuals and communities are better protected from harm. [12]

In engineering, reliability, availability, maintainability and safety (RAMS) [1] [2] is used to characterize a product or system: Reliability: Ability to perform a specific function and may be given as design reliability or operational reliability; Availability: Ability to keep a functioning state in the given environment
From a safety standpoint, EHS involves creating organized efforts and procedures for identifying workplace hazards and reducing accidents and exposure to harmful situations and substances. It also includes training of personnel in accident prevention, accident response, emergency preparedness, and use of protective clothing and equipment.
Software safety (sometimes called software system safety) is an engineering discipline that aims to ensure that software, which is used in safety-related systems (i.e. safety-related software), does not contribute to any hazards such a system might pose. There are numerous standards that govern the way how safety-related software should be ...
The information used to compile the safety case may then formally guarantee further specifications, such as maximum safe speeds, permitted safe loads, or any other operational parameter. A safety case should be revisited when an existing product is to be re-purposed in a new way, if this extends beyond the scope of the original assessment.
The safety assurance case is structured argument reasoning about systems appropriate for scientists and engineers, supported by a body of evidence, that provides a compelling, comprehensible and valid case that a system is safe for a given application in a given environment.
Some safety organizations provide guidance on safety-related systems, for example the Health and Safety Executive in the United Kingdom. [6] Risks of this sort are usually managed with the methods and tools of safety engineering. A safety-critical system is designed to lose less than one life per billion (10 9) hours of operation.
