NFPA 660.pdf

This file is a technical standard document—NFPA 660—which addresses the installation of sprinkler and standpipe systems in industries handling combustible particulates. The standard provides comprehensive guidance on fire protection requirements for facilities processing combustible materials, including wood dust, grain, sugar, and other similar substances. NFPA 660 establishes minimum design, installation, inspection, testing, and maintenance criteria to prevent and control fires and explosions in combustible dust environments. The document addresses system design parameters, sprinkler selection and spacing, standpipe requirements, water supply specifications, alarm systems, and ongoing maintenance protocols. It also covers housekeeping procedures and operational practices necessary to maintain system effectiveness.

This standard is directly applicable to the U.S. Army Heritage and Education Center (USAHEC) Dust Collection solicitation (W91QF026QA019), as the Exterior Dust Collection System (EDCS) being procured for the Exhibit Fabrication Shop in Building 952 must comply with NFPA standards for combustible wood dust collection and fire protection. The solicitation requires compliance with both current International Mechanical Code (IMC) requirements and National Fire Protection Association (NFPA) standards. Prospective contractors responding to this Army Materiel Command solicitation should reference NFPA 660 to ensure their proposed dust collection system meets the necessary fire protection and safety standards for woodworking and exhibit fabrication operations involving combustible wood dust handling.
