If you are smelling natural gas, you have a problem and should immediately call the gas company. They will come and check it out.
If you are smelling gasoline, then someone spilled some gasoline or something is not venting properly.
In either case, if the smell is strong, you might want to vacate the house and give the fire department a call to see if they can help.
No. But some gasses have odors. Natural gas doesn't have an odor but sulfur is added so it can be smelled. Otherwise a leak could go undetected and cause the death of someone living in a house.
There must be a gas leak. Contact your gas supplier IMMEDIATELY, if the smell is in a house. If it is in a car, have your mechanic check for a leak.
if you smell gas but cannot find the leak or source immediately get everyone out the house and go to the neighbors. call the police and then they will handle it from there
