The Department of Defense, specifically the United States Marine Corps (USMC), is conducting market research through a Sources Sought notice to identify qualified businesses capable of providing inspection, testing, cleaning, certifying, calibration, and maintenance services for personal protective equipment (PPE) utilized by Fire and Emergency Services (F&ES) across multiple installations in California, including Camp Pendleton, Barstow, Miramar, and 29 Palms. The objective is to ensure the operational readiness and safety of F&ES personnel by adhering to established standards set by the National Fire Protection Association (NFPA) and the Occupational Safety and Health Administration (OSHA). Interested parties are invited to submit their capabilities statements by June 18, 2025, to the designated contacts, as this Sources Sought is a preliminary step to gauge market interest and does not obligate the government to solicit bids in the future.
