What is safety case development?

The development and auditing of Safety Management Systems. Developing supporting arguments that all hazards have been adequately addressed and relevant safety requirements met. Providing guidance and rationale for safety assessment methods and criteria employed.

How do you write a safety case?

The safety case should include an introduction and sections, arranged in the following order:

1. The main parameters and specifications machine and (or) equipment;
2. A common approach to safety at designing of machines and (or) equipment;
3. Requirements for the reliability of the machine and (or) equipment;

What is safety case approach?

A safety case approach, as used in the United Kingdom (UK), Australia and Norway, requires a detailed analysis of hazards and steps taken to address those hazards, and thus minimize or mitigate the risk.

What is a safety case nuclear?

5.1 The nuclear safety case is a term used to encompass the totality of the documentation developed by a designer, licensee or dutyholder to demonstrate high standards of nuclear (including radiological) safety and radioactive waste management.

Who needs a safety case?

Safety cases are often required as part of a regulatory process, a certificate of safety being granted only when the regulator is satisfied by the argument presented in a safety case. Industries regulated in this way include transportation (such as aviation, the automotive industry and railways) and medical devices.

What is a safety case HSE?

The safety case is all the information you use to manage the risk of fire spread and the structural safety of your building.

What is a safety case author?

The Safety Case Author works within a team of nuclear safety professionals to produce a Safety Case. They need to take a holistic approach to assessing operations and therefore often have experience in varied aspects of the nuclear sector.

What is included in a safety case?

A safety case is a written demonstration of evidence and due diligence provided by a corporation to demonstrate that it has the ability to operate a facility safely and can effectively control hazards. The primary use of safety cases in an occupational health and safety context is in the process industries.

What is the purpose of a safety case?

Why do we need a safety case?

The purpose of a safety case is to provide a structured argument, supported by a body of evidence, that provides a compelling, comprehensible and valid case that a system is acceptably safe for a given application in a given context.

What is a safety case iso26262?

What is a railway safety case?

A Railway Safety Case (RSC) is a particular form of safety case which places a legal obligation on an organisation to document their commitment to safety, together with how proper discharge of these commitments will be made in their respective activities.

How are safety cases used in agile development?

Agile development methods have been applied to safety case production. The review of safety cases is an important activity in the safety engineering process, performed throughout development, operation and maintenance, in which the safety case argument and evidence are scrutinized and challenged.

When does a safety case need to be revisited?

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. A safety case aims to show that specific safety claims are substantiated and, in the UK, that risks are kept ‘As Low As Reasonably Practicable’ ( ALARP ).

What are the elements of a safety case?

A safety case requires two elements: Supporting Evidence Results of observing, analysing, testing, simulating and estimating the properties of a system that provide the fundamental information from which safety can be inferred High Level Argument

Why do we need a safety case in the UK?

Such standards typically do not explicitly require an explicit argument for safety and instead rest on the assumption that following the prescribed process will generate the required evidence for safety. Many UK standards are non-prescriptive and call for an argument-based approach to justify safety, hence why a safety case is required.
