Diesel Engine Safety Overview
Hydrocarbon Release and
Diesel Engine Runaway
A hydrocarbon release can occur at any
time in drilling, production and refining
environments. A large number of diesel
engines are used in equipment for daily
operations at these sites, including vehicles,
lighting towers, power generators and
construction equipment.

Automatic, self-contained valves

Custom engineered valves and systems
Operating a diesel engine in a hydrocarbon
environment can be a serious safety risk to
personnel and equipment. A hydrocarbon
vapor can be drawn into the air intake
system of a diesel engine and act as an
uncontrolled fuel source. This can cause
the engine to accelerate and overspeed or
runaway, leading to dangerous mechanical
failure and potential ignition source for an
explosion. An operator cannot shut down a
runaway engine by turning off the ignition
because the engine is running on an external
fuel source.
The most effective way of shutting down a
runaway diesel engine is with an air intake
shutoff valve system. This system completely
blocks the engine intake system, cutting off
both the external fuel source and the air
required to keep the engine running.
