Inspection of chemical
storage tanks

Society’s concern for the environment placed an enormous amount of pressure on oil companies to improve their environmental, health and safety practices.

When hazardous substances are stored, reducing the risk of leaks is of utmost importance. The corrosion of the storage tank may cause pollution to the environment and losses. For that reason, the storage facilities for petroleum liquids, both tank farm storage and facilities for their consumption on individual premises and to supply vehicles, should be subject to the necessary regulatory inspections to verify their tightness, mechanical resistance and their safety devices.

With our cleaning service for chemical products, you guarantee a correct condition and maintenance of the tanks.

CHARACTERISTICS OF THE CLEANING OF CHEMICAL PRODUCTS

Society’s concern for the environment placed an enormous amount of pressure on oil companies to improve their environmental, health and safety practices. 

When hazardous substances are stored, reducing the risk of leaks is of utmost importance. The corrosion of the storage tank may cause pollution to the environment and losses. For that reason, the storage facilities for petroleum liquids, both tank farm storage and facilities for their consumption on the premises itself and to supply vehicles, should be subject to the necessary regulatory inspections to verify their tightness, mechanical resistance and their safety devices.

At Rafibra, we are aware that the early detection of a potential deterioration of equipment prevents any escape of the content from the facilities that may involve a fire hazard or explosion and the emission of discharges that are harmful for the environment.

According to the Regulation on the Storage of Chemical Products approved by the aforementioned Royal Decree, regulatory inspections of the storage of flammable and combustible liquid products (ITC-MIE-APQ 01) can only be carried out by specialist companies that are certified by an Approved Inspection Body.

The facilities intended for the storage of chemical products must be reviewed and inspected periodically to guarantee their safety. This is due to the fact that these stored chemical products are usually highly flammable or hazardous. Incorrect storage could lead to a high risk of accident. Hence, the importance of performing periodic checks.

Transitory provision number three. Royal Decree 656/2017, of 23 June, approving the General Regulation of Storage of Chemical Products and its Complementary Technical Instructions MIE APQ 0 to 10.

Reviews and periodic inspections of the existing facilities. 

The storage of chemical products, already existing upon the entry into force of this Royal Decree will be reviewed and inspected in accordance with the technical requirements of the Complementary Technical Instructions according to which they were stored. The frequency and criteria to carry out the reviews and inspections will be stated in the Complementary Technical Instructions (CTI) approved by this Royal Decree. The deadline for carrying out the first review and inspection will be counted from the last periodic inspection carried out, in accordance with the previous CTIs or, in their absence, from the date of authorisation or communication of the release into service of the storage.

Según, la disposición transitoria tercera. Real Decreto 656/2017, de 23 de junio, por el que se aprueba el Reglamento de Almacenamiento de Productos Químicos y sus Instrucciones Técnicas Complementarias MIE APQ 0 a 10.

Realizamos la limpieza de la forma más efectiva y segura, una vez desgasificado el depósito y controlando que los gases de la atmosfera del interior del tanque están por debajo del 1 % de L.I.E, en todo momento.

Debemos conocer con detalle qué tipo de producto químico es el que vamos a almacenar para adaptar las características del almacén y el sistema de almacenaje. Los productos químicos son compuestos creados en procesos industriales o de laboratorio y tienen diversos usos y aplicaciones en la sociedad actual.

Es importante almacenar productos químicos de forma separada y correctamente etiquetados con su nivel de riesgo para poder identificar rápidamente el tipo de sustancia y su peligrosidad.

Según el Reglamento de Almacenamiento de Productos Químicos aprobado por el citado Real Decreto, las inspecciones reglamentarias de almacenamientos de productos líquidos inflamables y combustibles (ITC-MIE-APQ 01) solo pueden ser realizadas por empresas especialistas y certificada por una OCA, Organismo de Control Autorizado.
