Now I know, I thought gas has odors that's why it's stinks on nose, however due to watching different facts I learned that gases are odorless and smell was added to determine if there's a leak on tank, it's a great prevention on fire. Imagine if gases had no smell, then it's hard for people to determine if the gas already leaking that may lead to accidents.😊
