Mobile processing units: Code of practice

Last updated: 19 December 2024

This Code sets out the requirements for the design and operational management of Mobile Processing Units (MPUs) used in the manufacture and blast-hole delivery of explosives used in surface and underground blasting as well as other operations, including field packaging.

Unless otherwise specified, this Code applies to the operational transport, manufacture and delivery of products using MPUs on public roads and private property throughout Australia, including mining leases. It includes the on-site1 carriage of small quantities of detonators and boosters intended for immediate use in tasks directly related to the operation of the MPU. It also includes the carriage of small quantities of explosives samples2 returned for quality monitoring purposes.

This Code does not apply to the transport of dangerous goods in vehicles or equipment not specifically covered or included by definition. The intent of this Code is to ensure a level of consistency in the design and operational management of MPUs, and further the objective of increased safety across the commercial explosives industry. 

Due to the specialised application of MPUs, this Code was developed to cover a gap between the ADG Code and AEC. Design changes in this revised version are not intended to be applied retrospectively.
