IS 15394:2003 is the Indian Standard (BIS) for fire safety in petroleum refineries and fertilizer plants - code of practice. This code of practice provides guidelines for fire safety in petroleum refineries and fertilizer plants. It covers crucial aspects such as plant layout, spacing between equipment, design of fire protection systems (hydrants, water spray, foam), and requirements for fire detection, alarm systems, and emergency management.

| Parameter | IS Value | International | Source |
|---|---|---|---|
| Foam Application Rate (Cone Roof Tank, Hydrocarbon) | 5.0 lpm/m² | 4.1 lpm/m² (0.10 gpm/ft²) | NFPA 11 |
| Cooling Water Rate (Adjacent Exposure Protection) | 3.0 lpm/m² on exposed surface | 4.1 lpm/m² (0.10 gpm/ft²) on exposed surface | API RP 2030 / API RP 2001 |
| Minimum Firewater Header Pressure | Minimum 7.0 kg/cm²g maintained in the network | Design for 100-150 psi (7-10.5 kg/cm²g) to ensure adequate pressure at the most remote device. | API RP 2001 |
| Tank Spacing (Floating Roof, Stable Liquid) | Based on OISD 118, e.g., (D1+D2)/6 with minimums, or 40m for very large tanks. | 1/6th sum of adjacent tank diameters, but not less than 3 ft (0.9 m). | NFPA 30 |
| Fire Pump Standby Philosophy | 100% standby capacity of the largest pump is typically required (e.g., via a diesel pump). | Pumps shall be provided to meet the required flow with the largest pump out of service. | NFPA 20 |
| Fire Hydrant Spacing | Maximum spacing of 30 m in process units. | Located not more than 150 ft (45 m) apart in process areas. | API RP 2001 |
