Safe Process
Safety measures:
lLevel 1: No leakage of hydrogen → safety features of the equipment, involving selection of parts, safety monitoring, hazop/LOPA analysis, and SIL rating
lLevel 2: Real-time detection of any leakage and prevention of further leakage → safety control system design, involving monitoring in the entire plant
lLevel 3: No accumulation of gas in case of any leakage → ventilation engineering design for safety
lLevel 4: Ignition sources eliminated → no-smoking and other safety management principles
lLevel 5: Minimum impacts on the surroundings in case of any fire accident → approval and design of safety facilities such as explosion-proof walls and safety distance
