CSA Regulations for Air Intake Shutoff Device on
Heavy Duty Tank Trucks

 

 

The deadline is fast approaching for compliance to CSA regulation B622-14 which states that diesel engine highway tank trucks or portable tanks containing dangerous goods (class 2.1, primary class 3, or subsidiary class 3) must be equipped with an automatic engine air intake shutoff device to prevent diesel engine runaway in the event of exposure to combustible vapors. In addition, this device must activate automatically if engine overspeed is detected and remain activated until it is manually reset.

For Class 2 dangerous goods, CSA B622-14 states:

The device shall activate automatically if engine runaway is detected and remain activated until manually reset.

For Class 3 dangerous goods, CSA B621-14 states:
7 Use of means of containment
