更正一個小細節:天然气的压力其实只有1/4 psi( pound per square inch),比我印象中的还要低,煤气管的截面也就大约1个平方英寸,那么压力只有100多克的重量,人的大拇指就可以堵住了。所以我说天然气是很安全的。而水的压力就大得多了,大概50-60磅的重量。Just correct a small mistake: the natural gas pressure to residential home is around 1/4 psi, I thought it is 1-3psi, actually it is lower, and that means it’s safer.

Thank you for sharing your experience and tips for replacing a natural gas furnace in your own house. Mercaptan is added to natural gas (~90 -95% methane) in distribution system to make it smell like rotten eggs (or sulphur) for safety. An explosion can only occur when fuel concentration is within 5-15%, for methane and gasoline vapor. It is always good practice to ventilate work areas to control exposure to airborne contaminants and vapours.
