193 - Fire Fundamentals pt. 15 - Extinguishing systems with Bogdan Racięga

Fire Science Show

Welcome to another Fire Fundamentals. This time the episode is focused on various extinguishing technologies. Invited guest - Bogdan Racięga, Director at Baltic Fire Laboratory and expert in fire protection systems breaks down the fundamental differences between suppression and extinction technologies and how they work in real-world applications.

• Clear distinction between suppression systems (control fires while meeting temperature criteria) and extinction systems (must completely extinguish fires)
• Types of fire protection systems including water-based (sprinkler, water mist), foam, aerosol, and gas systems (no fire-balls :))
• Technical parameters affecting performance: K-value, nominal working pressure, RTI, discharge areas
• Areas of application, eg. why water mist systems can often be preferred for high-rise buildings due to smaller piping and reduced weight
• How temperature ratings and RTI affect sprinkler activation timing and performance
• Challenges with concealed sprinklers including maintenance issues and delayed activation
• Testing procedures for water distribution patterns and certification processes
• Differences between high-pressure and low-pressure systems in various applications
• nuances related to the role of an accredited laboratory (ISO 17025) and a certification body (ISO 17065)
