Broken medical device leaks mercury, prompts evacuation

The Pocatello Fire Department responded to a hazmat situation Friday after a medical device broke and leaked mercury.

The incident occurred at a medical office 1151 Hospital Way Suite A Friday. According to the fire department’s report a large sphygmomanometer, a blood pressure measurement device, broke and leaked out the mercury the device uses.

An employee initially tried to clean up the spill but then contacted Poison Control who directed them to contact the fire department. To prevent further contamination the building was evacuated.

Crews verified there was a mercury spill in one room of the building. Assistant Chief Williams called for Engine 2 to bring up testing equipment from the HazMat Truck and contacted the State Communications Center to initiate a Bridge Call with DEQ, State /Local health agencies, BHS, and the EPA.

All personnel in the building were tested and contaminated clothing and items collected for cleaning or disposal. Investigation revealed the potential of cross contamination to other sites. All known sites and clothing were tested and the contaminant was either mitigated when found or items were collected for disposal.

Investigation also revealed that the spill had occurred on the day previous and was exacerbated by vacuuming. The Pocatello Fire Department does not believe there is further risk of exposure and urges all residents who experience a mercury spill to not attempt to sweep or vacuum mercury. In the event of a spill, residents are advised to evacuate the immediate location of a spill, call 911, and minimize travel distances until exposure has been verified.
