LYTTON – A potentially fatal cloud of hydrogen sulfide gas that developed near a well Monday afternoon sent two people to hospital.

The incident happened around 1:15 p.m. in Lytton.

The two men, one of whom had briefly stopped breathing, were taken to Loring Hospital in Sac City. A report on their conditions was not available Monday evening.

A team from Carroll’s Sargent Drilling was injecting 110 gallons of hydrochloric acid into the well when a chemical reaction occurred, according to Fort Dodge Fire Chief Steve Hergenreter. He said that a large cloud of what was later identified as hydrogen sulfide was created.

A worker in the well building was submerged in gas, Hergenreter said. One of his colleagues entered the building and took him out.

Hergenreter said the submerged worker was not breathing when he was removed from the building. He said Calhoun County 911 dispatchers asked the second man to perform CPR. As a result, the patient was breathing when emergency personnel arrived.

The Region V Hazardous Materials Response Team managed by the Fort Dodge Fire Department was called to the scene.

Hazardous materials team members in full protective gear identified the gas as hydrogen sulfide. Hergenreter said at the time that the amount of gas in the well was 10 times the level at which it is considered lethal.

The Hazardous Materials team flushed the acid back into the well, eventually dissipating the hydrogen sulfide.

The Lytton Fire Department, Calhoun County Emergency Medical Service, Calhoun County Sheriff’s Deputies and Calhoun County Emergency Management responded to the scene with the Hazardous Materials team.
