The only 'emergency shutdown' switch on my Newell is an override switch used to allow the engine to operate for 30 seconds to move the vehicle to a safe location when the DDEC shuts the engine down due to low coolant, low oil, or high oil temperature.
In motorhomes, engine runaways are very rare. They are typically caused by a failure that results in quantities of oil being sucked into the cylinders either due to a blown gasket or turbo/blower seal. If that were to happen, the best way to stop the engine is to block the flow of air into the cylinders by blocking the air intake with something virtually air tight. No air, no runaway.
