The proposed structure combines three shipping containers which are filled with smoke to simulate breathing apparatus rescues in confined spaces.

The structure will also be used for roof training using harnesses and ropes above two containers stacked on top of each other.

District manager for the MIA district RFS, Kevin Adams, said other professions could get in on the act.

"It can be utilised for confined space training amongst staff of councils, wineries, rice mills and the like, they all have to do it," Mr Adams said.

"Councils for instance have to train people who go down tight manholes and pump-out pits, and wineries have to provide the training for people working within tanks.

"However the primary purpose is to teach RFS, SES and NSW Fire and Rescue how to be safe in difficult situations."

Walls within the containers can be moved around creating different rescue scenarios.

Mr Adams said the training would be invaluable to teach people how hazardous working in smoky conditions could be.

"It will make people aware that they can't see in smoke, so people don't just tear into a house, get lost and can't get out again," he said.

"A hallway will be simulated and you can go into either container and the walls can be changed around so it is a great form of training."

Mr Adams sought to clarify that while the containers would be filled with smoke, they would not be heated.

The facility will be erected somewhere on the land adjoining the Griffith sewerage treatment plant once Council determines the precise location of the relocated dog pound.

The RFS will be responsible for all costs associated with the preparation of the five-year license agreement.
