The accident occurred on the SS85 highway, between the Isernia Nord and Isernia Centro exits, starting from the late morning , and stretching into the following day.
The Isernia Fire Department, alongside the local NBCR (Nuclear, Biological, Chemical, and Radiological) unit, was on the scene to handle the crisis.
The severity of the incident necessitated additional support from the NBCR specialists from the Bari command, who are trained in the delicate task of transferring hazardous materials.
The operation involved not only securing the area but also transferring the potent acid from the overturned tanker, a task carried out with the cooperation of the transport company.
Sulfuric acid, known for its corrosive and highly reactive properties, posed a significant risk to both human safety and the environment, making the intervention of such specialized units critical.
Loading , carrying at sea & discharging of Sulphuric acid involve high risk and require sophisticated handling for safety, health and loss prevention reasons. They need careful consideration prior loading , tank coating compatibility, cross compatibility with other cargoes carried, environmental controls if required (inerting).
Product safety data sheets may be available from various sources. For safety preparation, until the specific product safety data sheet can be obtained, the Chemical Data Guide for Bulk Shipment by Water (U.S. DoT), should be used. Concerning the IBC/BCH code (respective 16.2/5.2) the master should request the specific product safety data sheet before commencement of loading. The safety data sheet posted must be in a language understood by ship's Officers and Crew (English).
Ensure that there is on board sufficient acid resistant hoses for the cargo transfer. Ensure that there is on board sufficient acid spray shields to cover flanges on manifold and hose connections
IBC code compatibility chart strictly prohibits water in adjacent compartment to Sulphuric acid as you are aware if both come in contact with each other will generate a violent reaction. It is therefore recommended that the during loading of sulphuric acid adjacent ballast tanks to be always stripped dry to the maximum efficiency of the deballasting equipment used.
Sulphuric Acid is normally carried in stainless steel tanks with a minimum concentration of 90% and at temperatures not exceeding 35C.
Highly concentrated, sulphuric acid may be carried in mild steel tanks, but only after obtaining special permits from the class.
It is highly recommended that Chemical suits to be worn by all the deck hands involved in the cargo handling.
