This addition of Test Your Skills will look at safety concerns related to cross-connection control testing and surveys related to confined spaces and other hazards.

If you have any comments, questions or suggestions please contact Backflow Prevention Journal’s Technical Editor; Sean Cleary at sean.cleary@iapmo.org.
