OHD LLLP

OHD LLLP, doing business as Occupational Health Dynamics, is a small-business manufacturer of respiratory protection equipment and occupational health diagnostic systems operating as a prime contractor exclusively across 93 distinct federal customer agencies, competing in full-and-open procurements without set-aside designation on the majority of awards (though some Total Small Business set-aside purchases appear in the portfolio).

Based in Birmingham, Alabama, OHD LLLP specializes in two core product lines grounded in the award history: quantitative respirator fit testing systems (QuantiFit and QuantiFit2 platforms, along with AeroFit systems) and associated calibration, maintenance, and inspection services; and occupational health diagnostic equipment including audiometers, dosimeters, and personal air sampling systems. The company also manufactures N95 fit tester masks and respiratory accessories. Primary NAICS classification spans Electromedical and Electrotherapeutic Apparatus Manufacturing (70 awards) and Medical, Dental, and Hospital Equipment and Supplies Merchant Wholesalers (62 awards), with secondary concentration in Other Measuring and Controlling Device Manufacturing. PSC categorization clusters around Medical and Surgical Instruments, Equipment, and Supplies (79 awards) and Safety and Rescue Equipment (35 awards).

Customer concentration is acute and Navy-centric. The top five funding agencies account for 42 percent of awards but only 68 percent of combined potential value, indicating a high-volume, lower-dollar customer base paired with fewer, larger Army and Air Force procurements. The Department of Justice Federal Bureau of Investigation Headquarters Division dominates dollars (30 awards, $3.4 million combined potential value), anchored by a $148 thousand Blanket Purchase Agreement for QuantiFit calibration and maintenance services and a $1.34 million total small business set-aside purchase order for Quantifit respirators and associated services. The Navy Installations Command (33 awards, $730 thousand) and Naval Sea Systems Command (29 awards, $837 thousand) drive volume; the Air Force Air Mobility Command is the second-largest dollar customer with a single $1.32 million total small business set-aside award in April 2024 for 61 QuantiFit2 systems to Travis Air Force Base. The Department of Veterans Affairs, Bureau of Prisons (Federal Correctional Complexes), Drug Enforcement Administration, and Army National Guard round out the repeating customer set.

OHD LLLP holds a multi-year BPA structure. Two parent vehicles surface: an Indefinite Delivery Contract (DJF171200V0005276) with the FBI carrying 5 task orders and $640 thousand combined potential value, and a Blanket Purchase Agreement (15F06721A0002227) also with the FBI encompassing 3 task orders and $67 thousand. Beyond these vehicles, OHD LLLP operates exclusively through firm-fixed-price purchase orders issued directly by individual agencies, with no participation in GSA Schedules, GWACs, or civilian agency-wide IDIQs reflected in the source data.

Activity has been flat to modestly declining. The vendor recorded 7 awards in 2022, peaked at 17 in 2023, and has averaged 13 annually in 2024 and 2025, with only 3 awards recorded through mid-2026. Only three awards carry ultimate completion dates within the next twenty-four months (combined potential value $93 thousand), indicating minimal recompete exposure in the near term—a function of the vendor's short-duration purchase-order posture and the long tail of completed historical work.

The combined potential value across all 263 awards is $9.4 million, with $8.9 million (94 percent) obligated, reflecting the small-dollar nature of OHD's federal footprint. The vendor has been registered with the federal government since at least 2001 and has operated without subcontractors throughout the award history; all 263 awards are direct prime contracts. Geographically, performance occurs predominantly in Birmingham or Hoover, Alabama (company headquarters) and Portsmouth, Virginia (for Navy calibration services), with some field deliveries to military installations and federal facilities nationwide. OHD's competitive posture relies on brand-specific procurement justifications citing QuantiFit system superiority for Navy quantitative gas-mask fit testing and the vendor's established OHD-manufactured equipment already in use across agency installations, limiting open competition on a significant portion of the order book.

OHD offers on-going service, support, and calibration on equipment sold. This includes annual calibration for the OHD FitTester 3000, Quantifit, doseBadges, and sound level meters. On-site calibration is available for most brands of audiometers. All parts, accessories, and supplies are available through OHD.
