Final answer:
The relief valve discharge from an LP-gas motor/mobile fuel container installed on a vehicle must be directed or vented safely away from any potential ignition sources to prevent the risk of fire or explosion.
Step-by-step explanation:
In the case of an LP-gas motor/mobile fuel container installed on a vehicle, the relief valve discharge must be directed or vented safely away from any potential ignition sources. This is to prevent the risk of fire or explosion due to the release of flammable gas.
For example, the relief valve discharge may be directed towards an open area away from the vehicle, or it may be vented through a separate pipe away from any potential spark-producing components.
Compliance with safety regulations and standards is crucial when installing and operating LP-gas systems to ensure the protection of individuals and property.
