Have you experienced the distinctive “rotten egg” smell of a hazardous gas called hydrogen sulfide (H2S)? Occurring naturally from organic decay, for example, around sewage plants, H2S can be found in crude petroleum and natural gas — often in very high concentrations.
The danger arrives with trucks bearing tons of sand. Off-loading that sand – which may contain up to 99 percent silica – can send clouds of thick dust into the air, exposing the lungs of fracking workers who are performing the task to serious inhalation hazards.
On May 19th, 2014, NIOSH posted a Science blog titled “Reports of Worker Fatalities during Flowback Operations.” This blog post provided information that NIOSH received from several sources indicating that acute exposures to hydrocarbon gas and vapors likely played a role in the deaths of at least four workers in the oil and gas extraction industry.
Survey finds more than half of oil and gas industry safety experts are unaware and unprepared to meet threshold

Reconfirming the need for strengthening oil and gas industry education and training is the “The 1ppm (parts per million) Hydrogen Sulfide Threshold: Are you prepared?” survey completed by Dräger, an international leader in the fields of medical and safety technology, in association with the American Society of Safety Engineers (ASSE), the world’s oldest professional safety society.
