Information about the company  KSO Edelstahlbeizerei GmbH

Since 1999, KSO Edelstahlbeizerei GmbH has been operating a stainless steel pickling plant at its Wilnsdorf site. Contracted pickling orders are the main work at the stainless steel pickling plant. The stainless steel parts are treated in immersion baths consisting of a mixture of hydrofluoric and nitric acid. Large pieces are pickled manually with hydrofluoric and nitric acid.

The pickling solution for stainless steel in the baths consists of hydrogen fluoride acid (hydrofluoric acid), nitric acid and water with a maximum concentration of < 7% hydrofluoric acid: 25% nitric acid, and the rest water. In accordance with hazardous substance regulations, the pickle prepared is toxic and corrosive, and labelled with the following R-phrases: R 23/24/25 toxic by inhalation, if swallowed and in contact with the skin. R 35 causes severe burns. The precursors for the pickle, at the time classified as very toxic and corrosive, are stored in the warehouse in 1 m³ IBC containers.

Due to the amount of toxic materials handled in the operating area, the operation is subject to Hazardous Incident Regulations. First and foremost, in the event of an incident in connection with a leaking bath there is a fatal risk of chemical burns to staff in the direct vicinity. The leaked contents of the batch are caught by the specially designed spill cup. Where the capacity of the spill cup is also exceeded by the use of fire-fighting water or intermittent heavy rainfall, the contaminated water may reach the exterior, enter the ground, enter the sewer system via floor drains, and enter the wastewater treatment plant or directly into the Heckebach body of water. Nevertheless, the risk is less than for the staff as the substances are heavily diluted by the water.

In the event of a fire-related incident, the immediate neighbourhood may be affected by smoke. Nevertheless, the smoke is no more dangerous than with a fire at another industrial unit.

Safety measures

Comprehensive safety measures have been installed to rule out or, as may apply, directly tackle an incident. As such, the spill cups are of a sufficient size to capture the escaping acid. KSO Edelstahlbeizerei GmbH confirms that it has also taken the best possible precautions with the emergency services for preventing incidents and limiting their impact as far as possible.

The staff is trained and the Fire Brigade informed and drilled in the location and dangers. The operational area is subject to the provisions of the 12th Regulation for implementing the German Federal Immissions Act Incident Regulations (12th BImSchV). The relevant authority, Arnsberg Local Council, has been informed of all substances and measures in the operational area covered by the aforementioned regulation by means of submission of the safety report in accordance with Section 9(1) of the 12th BlmSchV. The authority responsible for civil protection has been informed about the operational area and has drawn up a hazard prevention and response plan for dealing with incidents and limiting their impact outside of the company site.
