ANALYSIS OF THE PHYSICAL LAYOUT OF AN LPG DISTRIBUTOR IN A MUNICIPALITY OF SOUTH FLUMINENSE IN ACCORDANCE WITH NR 20

Abstract

Liquefied petroleum gas (LPG) is widely used as a fuel and, due to its high flammability, requires strict safety regulations throughout the production and distribution chain. Among critical factors, the physical arrangement of storage and operational facilities plays a fundamental role in accident prevention and in protecting workers and the surrounding community. This study evaluated the compliance level of an LPG distributor with Regulatory Standard No. 20 (NR 20), which governs work involving flammable and combustible substances. The research was structured in three stages: first, a documentary analysis of the operational procedures and safety practices adopted by the distributor; second, a review of the safety plan and previous inspection reports; and third, an on-site inspection using a technical checklist to assess the physical arrangement, storage, handling, and transportation of LPG, as well as ventilation conditions, safety signage, and safety equipment. The results indicated that, despite a formal regulatory structure and operational controls, significant gaps exist in the practical implementation of the standards. Nonconformities were identified, including insufficient signage, inadequate distances between gas cylinder stacks, lack of full coverage for protection against weather, expired or absent fire-fighting equipment in certain areas, and deficiencies in ventilation and emergency lighting. These irregularities pose substantial operational risks, increasing the potential for accidents and compromising the safety of workers, installations, and the surrounding community. Therefore, it is recommended to restructure the facility layout, install fire barriers and detection/alarm systems, update and maintain safety equipment, reinforce signage and emergency lighting, review ventilation systems, and implement ongoing staff training programs. The study highlights that compliance with NR 20 is not only a legal requirement but also a crucial strategy for accident prevention and the protection of life and property.
