Advancements in Safe Storage and Compatibility of Chemical Substances: The Introduction of NBR 17160 in Brazil

The Brazilian Association of Technical Standards (ABNT) has taken an important step forward in enhancing safety measures concerning chemical substances with the introduction of the new standard "NBR 17160 - Safe Storage and Incompatibility of Chemical Products." This standard, which entered National Consultation on 02/19/2024 and is accessible until 03/19/2024, signifies a crucial development in the field of chemical storage and compatibility.

Background: This standard is built upon the foundation of the German international standard "TRGS 510 - Storage of hazardous substances in non-stationary containers." The primary focus of NBR 17160 is to establish criteria for determining storage classes of chemical products. This is achieved by utilizing hazard classifications according to NBR 14725 and transport classifications according to Resolution 5998/ANTT, which was the prevailing standard during the document's formulation.

Objective: The core objective of NBR 17160 is to provide a comprehensive framework for segregating chemical products based on their respective chemical incompatibilities. This approach is crucial in minimizing the risk of hazardous reactions between substances, ensuring the safety of storage facilities and personnel.

Key Features:

1. Creation of Storage Classes: The standard introduces a system of classes to facilitate the segregation of chemical products. This categorization is designed to align with the classifications of hazards according to NBR 14725, creating a standardized approach to storage.

2. Rules for Safe Storage: NBR 17160 establishes explicit rules for the safe storage of chemical products within each class. This includes specific guidelines for handling various groups of substances, such as explosives, flammable liquids, and oxidizing agents. These rules contribute to maintaining a secure environment and preventing accidents.

3. Alignment with International Standards: Drawing inspiration from international standards like TRGS 510 ensures that Brazil remains in sync with global best practices. This alignment enhances the country's ability to participate in international trade while upholding high safety standards.

Accessing the Standard: To gain insights into the intricacies of the NBR 17160 standard, interested individuals can access the full text on the ABNT website through this link. The document is located under the ABNT/CB-010 Chemistry committee, titled "PROJETO ABNT NBR 17160 Armazenamento seguro e incompatibilidade de produtos químicos." However, it's essential to note that the window for accessing and providing improvement comments closes on 03/19/2024.

The introduction of NBR 17160 marks a stride in ensuring the safe storage and compatibility of chemical substances in Brazil. This standard not only establishes clear guidelines for storage but also reflects a commitment to international standards, emphasizing the importance of safety in handling and storing chemical products. As stakeholders engage in the National Consultation, their input and feedback will contribute to refining and implementing a standard that sets a benchmark for safety in the chemical industry.
