Not to be confused with volume overload. Hypervolemia, or fluid overload, is the medical condition where there is too much fluid in the blood.

The smell was put into natural Gas in the aftermath of a school explosion in New London Texas 1937. 300 students and faculty members lost their lives after the school exploded and was leveled when the trapped natural gas was ignited. The School was being fueled by gas directly from the near by oil wells.
Always use gas detection equipment during purging operations or when otherwise working on gas piping systems to ensure that no natural gas is present that may result in a combustible or hazardous atmosphere. DO NOT rely on your sense of smell alone to detect the presence of natural gas. Consult your local plumbing code, mechanical code, international fuel gas code and/or your NJ Department of Community Affairs (NJDCA) for more information.
