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 ...
When software is involved in a system, the development and design assurance of that software is often governed by DO-178C. The severity of consequence identified by the hazard analysis establishes the criticality level of the software. Software criticality levels range from A to E, corresponding to the severity of Catastrophic to No Safety Effect.
An occupational safety management system (OSMS) is a management system designed to manage occupational safety and health risks in the workplace.If the system contains elements of management of longer-term health impacts and occupational disease, it may be referred to as a occupational safety and health management system (OSHMS) or occupational health and safety management system (OHSMS).
Environment, health and safety (EHS) (or health, safety and environment –HSE–, or safety, health and environment –SHE–) is an interdisciplinary field focused on the study and implementation of practical aspects environmental protection and safeguard of people's health and safety, especially in an occupational context.
Safety engineering is an engineering discipline which assures that engineered systems provide acceptable levels of safety. It is strongly related to industrial engineering/systems engineering, and the subset system safety engineering. Safety engineering assures that a life-critical system behaves as needed, even when components fail.
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.
IEC 61508 is an international standard published by the International Electrotechnical Commission (IEC) consisting of methods on how to apply, design, deploy and maintain automatic protection systems called safety-related systems.
A job safety analysis (JSA) is a procedure that helps integrate accepted safety and health principles and practices into a particular task or job operation.The goal of a JSA is to identify potential hazards of a specific role and recommend procedures to control or prevent these hazards.
