Follow the safety information for the exact machine and seek appropriate professional help. Fuel-handling, spark-testing and shutdown procedures must fit the equipment and situation; this draft doesn’t provide those instructions.
When contacting someone, say first that you suspect gasoline and explain what you noticed. Don’t touch, move or restart the machine to supply more detail.
Mention the fuel concern before anyone comes out
Say up front that you suspect a fuel leak and tell them where the machine is sitting. If moving it would mean handling equipment you’ve already stopped using, ask whether they can come to the snowblower instead.
A photo is optional, and only worth taking if you can do so safely. The directory is not an emergency service, and preparing a request here does not arrange help or confirm an appointment.
The technical and safety advice in this draft still needs to be checked against the manufacturer’s instructions by a qualified reviewer. Follow your machine’s manual.
