Occupational safety and health: a method to test the collection of 'grey data' by line managers.

This paper describes and discusses a method for collecting data relating to the potential for illness or injury to occur in an organization. The reason for using the term 'grey' is explained and the underpinning philosophy of fuzzy thinking is also discussed. The method used was an audit which attempted to measure the degree to which certain types of failure were present in one organization. The audit used a term approach in design and execution and was found to be a useful and useable tool for collecting information relating potential causes of injury or illness.
