How The ‘World’s Smelliest Substance’ Saves Lives
Taste is subjective. So is smell. But when the headline in the January 22, 2013 issue of The Mirror reads:
“The French stench: Gas leak from factory in France causes a stink 200 miles away in UK”
and the subheadline reads:
“The leak released a colourless gas called mercaptan – listed in the Guinness Book of Records as “the world’s smelliest substance”
… it’s a pretty good bet that this isn’t going to elicit a huge range of opinions about the scent of “mercaptan” – the odorant that is used to warn people of a gas leak. Almost any adjective conveying vileness will suffice: putrid, fetid, nauseating icky, etc.
The incident in question was a spill at the Lubrizol factory in Rouen, France in 2013. It’s difficult to tell which chemical spilled since “mercaptan” is a class of stinky compounds, not a unique chemical. In reality, it doesn’t much matter which mercaptan was spilled because all low molecular weight mercaptans are evil-smelling and different ones are used to add an odor to different types of natural gas.

Do not get caught in a situation where you employees do not know what to do in a leak situation.

Required OSHA Training
“Employers shall provide employees with effective information and training on hazardous chemicals in their work area at the time of their initial assignment, and whenever a new chemical hazard the employees have not previously been trained about is introduced into their work area. Information and training may be designed to cover categories of hazards (e.g., flammability, carcinogenicity) or specific chemicals. Chemical-specific information must always be available through labels and safety data sheets.”
