Diesel Engine Safety Solutions


Diesel engines are a potential source of ignition when used in areas where combustible gas, vapors or dusts may exist. The resulting conflagration can lead to catastrophic consequences for personnel, production and the environment.

If flammable gas or vapor is drawn into the air intake of a diesel engine it acts as an additional ungoverned fuel supply. This may result in uncontrolled engine over speed followed by dangerous mechanical failure or flash back through the intake and the ignition of the surrounding gas or vapor cloud.

Once a flammable mixture is being drawn into the engine intake it may not be possible to stop the engine by closing down the fuel supply.

International standards and regulations in the oil and gas industry specify that an air intake shutdown valve must be fitted to ensure a guaranteed rapid and safe engine shut down.
