Diesel engines play a vital role in various industrial applications, powering everything from heavy machinery to transportation vehicles. However, with great power comes great responsibility, especially when dealing with flammable gases or liquids. In Canada, regulatory bodies have implemented stringent measures to ensure the safety of personnel and assets, and one crucial component is the Automatic Positive Air Shut Off Valve (PASS). In this blog, we’ll cover the significance of PASS systems, the dangers of diesel engine runaway, and the regulatory requirements of businesses in the Energy Sector operating in Canada.

What is an Automatic Positive Air Shut Off Valve?

A Positive Air Shut Off (PASS) valve is a safety device designed to monitor a diesel engine’s RPM. In the event of a diesel engine runaway, where the engine uncontrollably accelerates by using flammable gases from the ambient air as fuel, the PASS valve engages. This action halts the air supply to the engine, preventing further acceleration and averting potential catastrophic consequences. Automatic PASS systems are triggered autonomously when the system detects signs of engine runaway, distinguishing them from manual systems that rely on operator intervention.

What is Dangerous About Diesel Engine Runaway?

Diesel engine runaway poses significant risks, both in terms of engine damage and safety hazards. If a diesel engine begins taking in fuel from the surrounding air, it can accelerate uncontrollably, potentially leading to engine failure and severe damage. Moreover, the elevated temperature can cause extremely high engine surface temperatures, creating a high risk of contact ignition of flammable gases.

Canadian Regulatory Requirements for Automatic Positive Air Shut Off Valves

The regulatory framework governing the installation of Automatic Positive Air Shut Off Valves in Canada is outlined in CSA B621-14 and B622-14. These regulations mandate the installation of automatic PASS valves on diesel engines involved in the loading or unloading of flammable gases or liquids. Compliance with these regulations is essential for businesses operating in the energy sector and other industries that handle flammable materials. If you do not have a working, automatic PASS valve installed, you could be given Notices of Non-Compliance, Inspection Officer Orders, Board-issued Safety Orders, Administrative Monetary Penalties, and finally, you could have your ability to operate your business revoked.

Why Does Canada Require Automatic Positive Air Shut Off Valves?

The requirement for Automatic PASS systems in Canada stems from a commitment to safety and the prevention of potential disasters. Incidents like the Texas City Refinery explosion and the Deepwater Horizon disaster serve as stark reminders of the catastrophic consequences of inadequate safety measures. Canada mandates the use of automatic systems to minimize the risk of human error and enhance overall safety in workplaces handling flammable materials. The simplicity and effectiveness of PASS systems make them an integral component in safeguarding personnel, job sites, and assets.
