  • Description

    Help ensure wastewater treatment facilities are safe and compliant by referencing NFPA 820, 2020 edition.

    Fire and explosion hazards in wastewater treatment plants and related collection systems are a significant safety concern. NFPA 820, Standard for Fire Protection in Wastewater Treatment and Collection Facilities, provides general provisions for construction, ventilation, and electrical installation in wastewater collection systems and liquid and solids treatment processes and facilities.

    The standard is a critical resource for engineers, designers, installers, contractors, facilities managers, and authorities having jurisdiction (AHJs) nationwide. NFPA 820 provides minimum criteria for safeguarding facilities as well as the hazard classification of specific areas and processes applying to:

    • Collection sewers
    • Trunk sewers
    • Intercepting sewers
    • Combined sewers
    • Storm sewers
    • Pumping stations
    • Wastewater treatment plants
    • Sludge-handling facilities
    • Chemical-handling facilities
    • Treatment facilities
    • Ancillary structures

    The revised NFPA 820 offers cutting edge information on fire and hazard protection of wastewater treatment plants.

    The 2020 edition covers the latest methods for helping to ensure personnel, public, and facility safety with new content and revisions to remain current with industry practices and technology.

    Vital updates include:

    • Added content to cover the protection of force mains
    • Relocated all caution text throughout the document to the annex
    • Added new sections emphasizing the importance of monitoring for flammable atmospheres prior to the performance of work that could introduce a source of ignition
    • Revised the definition for physical separation to clarify that personnel entry into physically separated spaces is by individual, exterior access ports with no physical connection
    • Added section permitting the use of an airlock as an alternative means of providing a physical separation
    • Added references for ventilation rates and procedures to protect personnel from the effects of toxic gases, oxygen deficiency, or biological hazards

    Make sure you have access to the latest methods of helping protect people and property in and around wastewater treatment facilities.
