Permit to Work
Safety Worker

Permit to Work is your front-line documented method of keeping people safe whilst undertaking any form of work that needs to be controlled in potentially hazardous environments. It represents the combination of formal risk identification, isolation, management & control, communication, and authorisation which forms a key component of an integrated safe system of work (ISSOW) for efficient Digital Control of Work.

Permit to Work has historically always been paper-based systems with multiple forms for each task that needs to be performed. However, in the age of digitisation, software and mobile solutions offer digital permit to work system software to control the risks, ensure worker safety and significantly increase efficiencies.
