Step 3
Explain why it is dangerous not to earth the pipe.
Answer
If the pipe is not earthed, static electricity can build up due to friction between the petrol and the pipe. This static charge can lead to a spark at the end of the pipe, which poses a significant risk of igniting the petrol and causing a fire or explosion.
Step 4
Explain how earthing the pipe makes this process much safer.
Answer
Earthing the pipe removes excess static charge that may accumulate. By providing a path for the charge to dissipate safely into the ground, the risk of a spark is significantly reduced, making the petrol transfer process much safer.
