Eden Prairie, MN – Sprinkler system contains fire at business with hydrofluoric acid

Six firefighters were taken to a hospital after they were exposed to hydrofluoric acid on Wednesday, July 15, during a business fire call in Eden Prairie. Eden Prairie Fire Chief George Esbensen said the call of a commercial building fire at SVT Associates, 7620 Executive Drive, came in around 4:37 p.m. and the first arriving engine and chiefs got there in less than five minutes. The fire was in one room of an office space occupied by the company.

“The fire sprinkler system was holding the fire in check and fire crews were able to make short work of the remaining fire. After the fire was knocked down and as overhaul was beginning several firefighters began to experience symptoms consistent with a chemical exposure,” he said. “Five firefighters from EP and one from Bloomington were transported to Methodist Hospital where it was determined they had been exposed through their skin with hydrofluoric acid.”

Esbensen said the acid is commonly used in metal etching and stripping. All six firefighters were treated and released by 11:30 p.m. the same day. They have since returned to duty.

There was some loss of equipment as a result of the chemical exposure. Turnout gear that was exposed to the chemical will not be able to be cleaned and there are 13 sets that need to be replaced. Additionally the department is waiting to hear what parts of the self contained breathing apparatus can be cleaned as well as other tools. The department doesn’t have exact replacement costs yet on the gear, but the estimate is around $50,000, Esbensen said.

“There are other items that were impacted but we haven’t determined the best course of action on those yet,” he said.
