Detecting Gases: What You Can`t Smell Can Hurt You

Walking through a drill-site area, a worker smells rotten eggs and stops tor a minute or two to assess where a gas leak might exist. Rubbing his itchv eves as he investigates further, he notices that he no longer smells the tell¬tale hydrogen sulphide odour. He does not realize that the gas has deadened his olfactory senses and unless he leaves the area within seconds, he could lose ...
