Step 3
Explain why it is dangerous not to earth the pipe.
Answer
Not earthing the pipe can lead to the buildup of static electricity due to friction. If this static charge accumulates, it could discharge suddenly, potentially creating a spark that might ignite the petrol vapor, causing a fire or explosion.
Step 4
Explain how earthing the pipe makes this process much safer.
Answer
Earthing the pipe allows excess charge to be removed and conducted away, preventing static buildup. This discharge of static electricity reduces the risk of sparks that could ignite flammable vapors and ensures a safer transfer of petrol.
