The paper deals with the leakage of nitric acid in road transport (ADR); its specifications, problems and complications during its leakage from the tank into the environment. The first part describes specific characteristics and their means of transport. Following part discusses the experimental investigation of the specific characteristics of HNO3. The experiments on reaction of nitric acid in contact with diesel, gasoline, valvoline engine oil and coolant as well as with samples of common vehicle’s materials such as iron, aluminium, copper, tire rubber, ABS plastic and asphalt. Reactions observed not always met the expectations of strong reactions as described in Security data sheet. The third part describes a possible ways of acid leakage from the tank and its disposal. Recommendation concerning effective action of Fire units are described in order to stop the leaking and minimize the damage caused by nitric acid.
