To help your fleet comply with new Canadian regulations CSA B621-14 (clause 7.1 (j)) and CSA B622-14 (clause 5.1 (i)), Diesel Tech Industries offers the most reliable remote positive air shutoff system on the market. The DTI Guardian Safety System is equipped with  “Intel-A- Valve-Technology”  (also known as an air intake emergency shutoff valve, positive air shutoff valve, or engine air intake shutoff device), that monitors vehicle data to analyze its operation and environmental conditions to autonomously detect runaway states and reacts by closing the air intake valve preventing damage and avoiding potentially dangerous situations.

Since diesel engines run on compression ignition, if hydrocarbons are introduced into the atmosphere, they can cause the engine to run away and potentially explode. In some cases, these hydrocarbons have been the ignition source for several chain reaction explosions that unfortunately led to major catastrophes causing loss of lives and billions dollars in damages.

Because of the catastrophes that have occurred and to prevent future disasters, the CSA  standard B621-14  are now enforced by transport Canada for any diesel engine that is running for any reason during the loading or off-loading dangerous goods with Class 2.1 or Class 3, or subsidiary class 3, shall be equipped with an automatic engine air intake shut off device.

A means of containment shall not be used unless the following conditions are fulfilled:

(i) no later than 1 Jan 2016, diesel engines on highway tanks and portable tanks containing dangerous goods of Class 2.1 and being used during loading or off-loading shall be equipped with an automatic engine air intake shut-off device that will prevent engine runaway in case of exposure to flammable vapours. The device shall activate automatically if engine runaway is detected and remain activated until manually reset.

A means of containment shall not be used unless the following conditions are fulfilled:

(j) as of 1 Jan 2016, diesel engines on highway tanks and portable tanks containing Dangerous Goods of primary Class 3, or subsidiary Class 3, and being used during loading or off-loading shall be equipped with an automatic engine air intake shutoff device that will prevent engine runaway in case of exposure to flammable vapours. The device shall activate automatically if engine runaway is detected and remain activated until manually reset.

A reminder, this regulation went into full effect as of January 12, 2018.
