At 10:20 AM this morning, Sweet Home Fire and Ambulance District was dispatched to a “Hazmat Incident” at 1540 Main Street in Sweet Home with the information of a possible gas leak and people not feeling well. During the initial investigation, Sweet Home Fire personnel used a gas monitor in an area in the back of the building where there was a strong smell of something resembling sulfur. The monitor alerted to carbon monoxide and hydrogen sulfide which is a gas that can be considered highly toxic at certain levels. The detection was strongest in an area with various cleaning chemicals in storage, a floor sink, and natural gas powered water heaters, so the decision to evacuate the structure was made. Northwest Naturas Gas and the State Hazmat Team were then notified and the area was cleared and monitored until those organizations could arrive to determine the source of the detection. After it was determined that the smell was not from the natural gas system and gas levels were at a safe enough level, fire personnel were able to investigate further. It was determined that the source of the gas was from several batteries located in a floor cleaning machine and a pallet jack that had batteries that were possibly failing during the charging phase and were producing carbon monoxide and hydrogen sulfide. The machines were removed from the building and fans were used to clear the building of any remaining gases. The building was determined “all clear” by fire personnel at approximately 1:20 PM. One employee was evaluated for nausea and breathing problems by Sweet Home medics with no transport. We would like to thank Northwest Natural Gas and the State Hazmat Team for their rapid response in bringing their expertise to this incident.
