Fire department aerial apparatus require periodic inspection and testing to remain safe and ready for emergency operations.  Apparatus manufacturer’s all require inspection and testing at least annually and occupational workplace regulations also require annual inspection and testing.  Agencies or jurisdictions which follow the NFPA 1911 standard will also have periodic inspection and testing requirements.

There are two distinctly different levels or types of aerial inspection and testing: the annual inspection and load test and the 5-year non-destructive testing. Often people confuse the annual load test with the non-destructive testing and are left outside of compliance with the apparatus regulations.  If you have any questions or would like to discuss your specific apparatus please feel free to contact us via telephone or email.  Our team is happy to share our knowledge with you in an effort to make your fireground a safer place to work.


When our team arrives at your station or the test location we will conduct a preliminary visual inspection of the apparatus and evaluate its apparent condition and determine if there are any conditions which may impact the safe execution of the inspection and testing.  After verifying that the apparatus and test location are suitable the apparatus will be setup for deployment.  From this point the entire inspection and testing process can take between 5 and 7 hours and the apparatus is generally not available for emergency service.  In the past situations have arose during the day that required the apparatus be made available and from the time of notification the apparatus can be returned to service in approximately 15 minutes.  Barring any such emergencies the inspection and testing protocol is as follows:

Perform cab controls and aerial operation interlock testing.
