Ask your propane company about permits as they'll usually handle this aspect of the installation and file all required paperwork. You can also contact the city code compliance office to ensure that all necessary gas permits and requirements are adhered to before the propane tank installation takes place.
Basically, a hernia is a defect in the abdominal wall that allows intestine to poke through. If the hernia becomes incarcerated (the intestine becomes strangled), then a blockage and rupture of the bowel can occur. This is life threateneing. Many people survive, but are permanently disfigured. A perforated bowel can mean months in the hospital, large portions of the bowel being removed, etc.
There are several different types of hernia: 1  Inguinal hernia is the most common. 2  Hiatus hernia is when part of your stomach pushes up into the chest through an opening in the diaphragm. 3  Femoral hernia happens when fatty tissue or a part of the bowel pushes through into the groin at the top of the inner thigh.
