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.
Internal hernias like a diaphragmatic hernia can affect the stomach, the esophagus, and diaphragm. If part of the stomach pushes through the opening at the bottom of the diaphragm (hiatus) or a weak area around the hiatus, it affects the digestive system.Internal hernias in other parts of the body are rare but have been known to affect the small intestine, causing obstruction within the intestine.n external hernia affects organs outside of the abdomen wall. The most common types of external hernias are inguinal, femoral, and umbilical. Depending upon its location, an external hernia can affect the groin area (inguinal, femoral) or naval area (umbilical).
