NFPA 17, Standard for Dry Chemical Extinguishing Systems

Stop Fire in Its Tracks. Keep Your Fire Extinguishing Systems Prepped to Perform.

There are more than 450,000 structure fires every year. Use NFPA^® 17, Standard for Dry Chemical Extinguishing Systems, to help ensure your dry chemical fire suppression systems are ready to function in the case of a fire.

This vital standard offers comprehensive requirements on the design, installation, testing, inspection, operation, recharging, and maintenance of these critical fire safety systems. The standard covers all components—detectors, nozzles, operating devices, storage containers, etc.—through their entire life cycle. Other key criteria covered includes:

• Total flooding
• Local application
• Hand hose line
• Engineered and pre-engineered systems
