Best to have an all clear. If the leak was located and fixed, and dispersed sufficiently from there, anyplace else should be fine.
True, better known as UEL and LEL (Upper and lower explosive limits)
Mercaptan is added to both propane and natural gas as both are odorless without this additive.
Without a properly calibrated gaspro or something similar to measure explosive/toxic atmospheres, one cannot simply say they are good to go.
Max, that is some seriously bad information to give out. Many people have been killed or severely burned due to ignorance or the feeling of it can't/won't happen to them.
Google Charlie Morecraft, and others, and see for yourself.
