The Guardian Basic Model is our entry level Guardian Safety System with Dash control and RPM Shutdown which offers superior protection in comparison with other air intake shut off valves in the market today.
As of January 2018 transport Canada regulations B621-14 and B622-14 requires an automatic engine air intake shutdown systems on diesel engines while loading or off-loading class 2.1 or class 3 dangerous goods. As well, the national energy board regulation SA 2015-02 requires every diesel engine that operates in or near oil and gas site to be equipped with an adequate air intake shutdown vale, our guardian basic is our entry level system that we recommend installing on vehicles and equipment.
To date the United States (OSHA) does not have any regulations in effect, however many oil and gas companies have as part of their safety programs a requirement or “best practice” for positive air shutdown systems on their sites.
Many US companies that deliver class 2.1 and class 3 dangerous goods to Canadian plant sites are required to have positive air shutdown system as well.
