Owners and operators of fleets:

To comply with the new regulations of CSA B621-14 (clause 7.1 (j)) and B622-14 (clause 5.1 (i)) Diesel Tech Industries offers the most reliable remote safety systems on the market today DTI Guardian Safety System 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.
Diesel engines run on compression ignition, so when hydrocarbons are introduced into the atmosphere, it can cause the engine to run away and potentially explode. In some cases, these have been the source of ignition for chain explosions that unfortunately have led to catastrophic losses of facilities, equipment and the most important of human lives.
For that reason and according to the new regulations above mentioned 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.
For Class 2 dangerous goods, CSA B622-14 states:

5 Loading and unloading requirements

5.1 General requirements

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.
For Class 3 dangerous goods, CSA B621-14 states:

7 Use of means of containment

7.1 General requirements

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.
