ISC designs rebreathing systems to meet the customer’s requirements and more. All products designed by ISC shall meet modern up to date standards for safety system design such as EN 61508 functional safety, the United Kingdom Minister of Defense 56, EN 61000, ISO 9001:2008 and other relevant standards that support quality assurance for safety-related instrumentation. Safety-related equipment is defined as any hardwired or programmable system where a failure singly or in combination with other failures/errors, could lead to death, injury, or environmental damage. ISC designs using a life cycle approach model. The model will define the life cycle, activities and defenses against systematic failures necessary to achieve functional safety and that it is used in stages of product development to include the operating life of the equipment. This is not just limited to electronics but includes breathing loop systems.
The model also defines proposed design architecture and if it meets the target failure probabilities. The safety assessment work exercises systematic methods of layer protection analysis and process hazard analysis. Two examples of this are FMECA (Failure Mode Effects Critical Analysis), and Fault Tree Analysis. This provides a Safety Integrity.
