# US Made Supply

> Specialty supply for compliance-driven work: hard-to-find American-made products spanning the building envelope, waterproofing, safety, fire protection, tools, and hardware. Comprehensive technical resources on building codes, fire safety standards, and compliance requirements.

US Made Supply connects contractors, facility managers, maintenance teams, and safety professionals with American-manufactured products that are often challenging to source through traditional channels. We focus on specialty items required for code compliance, retrofit projects, and specific safety and performance standards that typical suppliers don't stock.

Product categories include fire protection equipment (extinguisher brackets, K-Class kitchen extinguishers, marine-grade suppression, vehicle mount systems), wildfire and ember-resistant products (CBC Chapter 7A compliant vents, fire-rated gable vents, WUI-rated materials), specialty roofing and coatings (cool roof coatings, elastomeric coatings, sealants), emergency and life safety equipment (photoluminescent exit path marking, UL 924 inverters, panic hardware, area of refuge systems), specialized door hardware (Grade 1 closers, ADA-compliant hardware, delayed egress systems), safety and compliance products (ANSI/ISEA first aid kits, eyewash stations, bloodborne pathogen kits), and backflow prevention assemblies (RPZ, DCVA, detector check assemblies, test kits).

We serve contractors, building inspectors, facility managers, maintenance teams, and engineers with technical depth beyond basic specifications. Every product listing includes relevant standards, testing certifications, and compliance information.

Covers what Motorola R56 (Standards and Guidelines for Communication Sites, §3.12, edition 68P81089E50-C, April 2017) specifies for communication sites — a Class ABC unit for general fire fighting plus a 7-10 lb Class BC CO2 or clean-agent unit for the electronic equipment room, installed before equipment, with no water-based suppression used at comm sites — and where NFPA 76 (Fire Protection of Telecommunications Facilities, 2024) applies, including its Chapter 11 exemption that does not require extinguishers or detection in small unoccupied structures like cell huts. Explains why dry chemical is the wrong agent near energized electronics (NFPA 76 prohibits dry chemical and corrosive-liquid extinguishers in signal-processing, main distribution frame, and power areas because the residue can be catastrophic to the equipment), CO2 vs Halotron trade-offs for the equipment room (CO2 oxygen-displacement risk in a small unventilated shelter, NIOSH IDLH 4%; larger Halotron sizes carry an A:B:C rating), the standby generator and fuel area as a Class B exposure, unmanned-site inspection realities under NFPA 10 (monthly visual, annual maintenance, CO2 5-year and halogenated 12-year hydrostatic test), and Build America Buy America considerations for federally funded broadband infrastructure.

OSHA 29 CFR 1910.151(c) as the binding rule triggered by foreseeable exposure to injurious corrosive materials (per 2009 letter of interpretation). ANSI Z358.1-2014 (R2020) as the recognized industry standard cited to satisfy 1910.151(c) but not adopted by OSHA rulemaking (per 2002 letters): 0.4 GPM eyewash flow / 15 min, 3.0 GPM eye/face wash, 20 GPM drench shower / 15 min, tepid water 60-100 F (16-38 C), 10-second / unobstructed-path placement on the same level as the hazard (the 55-foot figure is a derivation, not the binding rule). Color-changing acid neutralizer chemistry (buffered base + pH indicator dye) as the response-floor companion to the eyewash. Acid-resistant PPE (neoprene/nitrile gloves rated for acid contact, splash goggles + face shield, poly/PVC apron, chemical-resistant boots). IEEE Std 1635-2022 / ASHRAE Guideline 21-2022 ventilation guide (non-mandatory, sized to keep room hydrogen below 25% LEL under worst-case overcharge). Step-by-step incidental-release procedure under OSHA 1910.120(a)(3) HAZWOPER exemption with explicit escalation to 1910.38 facility EAP when scope exceeds incidental. Lithium thermal-runaway scope explicitly walled off (HF acid byproducts, NFPA 855-2026, separate equipment and training).

Three fluid families with fundamentally different spill-response profiles: water-glycol (DLC, 25% propylene or ethylene glycol, low hazard, water-soluble), synthetic-hydrocarbon single-phase (PAO-based ElectroCool / Castrol ON / Shell Immersion S, Class IIIB combustible with closed-cup flash above 200°C, oil-only or universal sorbent compatible), fluorinated two-phase (3M Novec 7000-series and 649, Solvay Galden, Chemours Opteon, non-flammable but PFAS-regulated and produces HF at temperatures above approximately 500°C in adjacent-fire scenarios). 3M ceased PFAS-related fluid production end of 2025 with last order date March 31, 2025; Chemours Opteon 2P50 targeted commercial 2026. EPA TSCA 8(a)(7) PFAS reporting deadline October 13, 2026 for most manufacturers. NFPA 75-2024 §8.2.2 requires Class IIIB liquid with closed-cup flash ≥135°C, lid or access point, closed piping, and listed or approved equipment (does not mandate a specific suppression agent). UL 2417 immersion-cooling fluid testing service launched June 17, 2025. EPA SPCC 40 CFR 112 likely triggers at 1,320 gal aboveground threshold for hydrocarbon-based immersion fluids counting only containers ≥ 55 gal; water-glycol DLC fluids do not. Universal polypropylene sorbents are compatible across all three fluid families; oil-only sorbents reject the water-glycol component.

Hierarchy of risk control with de-energization plus 1910.147 lockout as the primary control; energized work permits per 130.2(B) only when LOTO is infeasible. ASTM D120 voltage-rated rubber insulating gloves with ASTM F496 six-month dielectric retest interval, glove classes 00 (500V) through 4 (36,000V) per Table 130.7(C)(7)(a). Arc-flash labels per 130.5(H) with nominal voltage, arc-flash boundary, incident energy plus working distance OR PPE category, and equipment-specific class. ASTM F1959 ATPV testing for arc-rated clothing. NFPA 70E is a consensus standard not an OSHA regulation, enforced via 29 CFR 1910.132 / 137 / 335 and the General Duty Clause per multiple OSHA letters of interpretation (2003-07-25, 2004-11-04, 2006-11-14, 2020-08-19). IEEE 1584-2018 incident-energy methodology with five electrode configurations (VCB, VCBB, HCB, VOA, HOA) over 208V to 15 kV.
