At least a dozen people were injured on Friday after a suspicious package was located at a DHL distribution centre in Langenzenn in southern Germany.
Several mail centre employees reportedly came into contact with an unknown white powder through a suspicious package, local media reported.
The mail centre staff later complained of feeling ill shortly after the package was discovered, including suffering from rashes.
The substance was found on the outside of the parcel and allegedly caused irritation. At least eight people were hospitalised after touching the powder.
However, a spokesperson for the regional police said this number could increase.
This discovery prompted a response from several emergency departments including police, firefighters and hazardous materials specialists. Around 100 emergency personnel were deployed.
Decontamination shower
A local fire department set up a decontamination site at the scene and the distribution centre was evacuated.
The police spokesperson told local media that a so-called decontamination shower had been taken to the warehouse.
Such a device can be used to wash off potentially hazardous substances. According to reports, 35 people have already used the shower.
Dangerous goods specialists are examining the package, but for now, it is unclear what it contains.
Meanwhile, the public has been asked to avoid the area until firefighters give the all-clear.
