On 18 March 2010, the Chief Inspector published guidelines for the renewal of item registration for diesel engine systems used in underground mines at a coal workplace. See LU10-01 Guidelines for the renewal of item registration for diesel engine systems used in underground mines at a coal workplace.

These guidelines require ExDES overhauls, code D examinations or explosion repairs after 1 October 2010 to be carried out by a "recognised service facility."

LU10-01 specifies requirements for an organisation to become a recognised service facility.

ExDES strategies

In-Service failure of explosion protected diesel engine systems (ExDES) a summary of reported incidents and findings from January 2010 to October 2011.

Safety Bulletin 12-01 In-Service failures of explosion protected diesel engine systems during 2010 and 2011 highlights the report and updates Safety Bulletin 10-06 Failures of explosion protected diesel engine systems.

One of the Department's strategies is to implement systems that will manage DES in a similar manner to explosion protected electrical equipment by 1 October 2013.

Recognised service facility application
