One or both kidneys may be enlarged and painful, and doctors may find tenderness in the small of the back on the affected side. Sometimes the muscles of the abdomen are tightly contracted. Irritation from the infection or the passing of a kidney stone (if one is present) can cause spasms of the ureters. If the ureters go into spasms, people may experience episodes of intense pain (renal colic).
NFPA 10 Standard for Portable Fire Extinguishers states that units weighing 40 lbs. or less be installed such that the top of the unit is not more than five feet above the floor. For units weighing more than 40 pounds, the top of the unit should be no more than 3.5 feet above the floor.
In the USA, NFPA 1 requires portable fire extinguishers to be mounted with their top no more than 5 feet from the floor, if under 40 pounds, no more than 3 1/2 feet (42 inches) if they are over 40 pounds. In both cases, the bottom of the fire extinguisher must be at least 4 inches from the floor, except for larger extinguishers mounted on wheels. NFPA 1: 13.6.8.1.3.8 (2009), with reference to NFPA 10: 6.1.3.8.
