The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking proposals for a sole source procurement of a fire extinguisher, identified by NSN 7R-4210-016708223-H5. The requirement includes a quantity of one unit, with delivery terms set to FOB Origin, and is subject to Government Source Approval prior to award, as the government lacks sufficient data to contract with other sources. This procurement is critical for maintaining safety and operational readiness, as fire fighting equipment is essential for various military applications. Interested vendors must ensure they meet the source approval requirements detailed in the NAVSUP WSS Source Approval Brochure, available online, and direct any inquiries to Casey M. Brown at casey.m.brown20.civ@us.navy.mil.
