ISRS™: for the health of your business

Best practice in safety and sustainability management


Organizations are under increasing scrutiny from stakeholders who expect ever higher standards of safety and sustainability. Satisfying the expectations of regulators, customers, employees and the public can be a matter of business survival.  

ISRS is a world-leading system used to assess, improve and demonstrate the health of an organization’s business processes. Using ISRS gives organizations and their stakeholders’ peace of mind that their operations are safe and sustainable.

In the current climate, with travel restrictions in place, ensuring and keeping high standards of safety and sustainability does not need to stop. Using remote technology DNV is still able to conduct interviews and review documentation and materials and provide assessment reports that will assure you to be aligned with  standards that ensure your operations are adhering to best practice in safety and sustainability. DNV customers in China are already benefiting from this approach using ISRS.

ISRS is available in 11 languages and has been implemented on thousands of sites worldwide. It includes tried and trusted tools that can be used in flexible ways to develop, train, implement, assess and benchmark safety and sustainability management.  

International Safety Rating System

ISRS represents more than 35 years of accumulated best practice experience in safety and sustainability management. Its continued success is testimony to its vision and strong foundation in research. 

The first edition was developed in 1978 by Frank Bird, a safety management pioneer, and based on his research into the causation of 1.75 million accidents.

ISRS seventh edition was launched in 2006. Its scope went beyond occupational health and safety management to address best practice in environmental, quality and security management and sustainability reporting.

ISRS eighth edition was launched in 2009. Its scope was expanded still further to help organisations improve process safety management, following industry concerns over the frequency of major accidents. It includes specific controls for managing major process hazards including fire, explosion and the release of flammable or toxic materials.

ISRS ninth edition was launched in April 2019. This edition is significantly updated in all areas and describes best practice in 10 loss categories: occupational health, occupational safety, process safety, security, environment, quality, asset integrity, energy, knowledge and social responsibility.
