IRC Guidelines for Fuel Station Access Design

Fuel station access design on National Highways requires strict adherence to specialized IRC guidelines, petroleum safety regulations, and NHAI operational standards. With fuel retail facilities generating high-frequency traffic and handling hazardous materials, compliance with IRC:86-1983, IRC:SP:84-2019, and petroleum industry standards is critical for approval success and operational safety.

Introduction

Fuel stations represent one of the most regulated categories of highway access facilities, requiring integration of traffic engineering, fire safety, environmental protection, and petroleum handling standards. The Indian Roads Congress (IRC) provides specific guidelines for fuel station access design that must be coordinated with Petroleum and Explosives Safety Organisation (PESO) requirements and local fire department regulations.
