Brevard County Hydrostatic Testing
Hydrostatic testing requalifies a pressure vessel to carry its rated charge for another service interval. NFPA 10 (2022) Chapter 8 sets the cycle for portable fire extinguishers (CO2 every 5 years, water and AFFF every 5 years, dry chemical every 12 years, wet chemical Class K every 5 years, halocarbon clean agent every 5 years). DOT 49 CFR 173.34, 180.205, and 180.213 govern shipping and requalification of compressed-gas cylinders, including SCBA bottles, medical gas, industrial gas, and propane. Florida pulls those federal requirements through Chapter 633, F.S. and Rule 69A-60, F.A.C., enforced by the State Fire Marshal and the local AHJ. We hold the State Fire Marshal hydrostatic testing facility licensure and DOT Requalifier Identification Number (RIN) the regulations require, and we run the Brevard County test stand at our shop with full audit-trail records.
The Brevard customer base spans the spectrum: Kennedy Space Center, Cape Canaveral Space Force Station, and Patrick Space Force Base SCBA fleets and clean-agent halocarbon storage; SpaceX, Blue Origin, ULA, Sierra Space, Astra, Firefly, L3Harris, Lockheed Martin, Northrop Grumman, and Boeing aerospace integration tooling and process gas; Health First, Parrish, and Steward hospital medical gas (Joint Commission EC.02.05.09); Port Canaveral cruise terminal and marine SCBA; Florida Tech and Eastern Florida State College laboratories; Brevard Public Schools custodial CO2; and beachside hotel CO2 and dry chemical fleets exposed to Atlantic salt-air corrosion. We pull each cylinder type through the same six-step process and stamp the right test mark on a passing cylinder.

Each cylinder arrives at our shop with a service tag, a description, and a pickup ticket. We log the manufacturer, the cylinder specification (DOT 4BA, 4BW, 3AL, 3HT, 3AA), the original test date, the requalification history, the agent, the rated working pressure, and the customer of record. Cylinders pulled from aerospace customers carry an additional asset tag tied to the prime contractor's contractor management portal. Cylinders pulled from Health First, Parrish, or Steward carry the medical gas asset tag and the Joint Commission EC.02.05.09 history. Inventory records sync to our portal so the customer can see status (received, queued, in-test, passed, condemned, recharged, ready for pickup) in real time.
Cylinders requiring internal inspection (12-year dry chemical, 5-year wet chemical, 5-year halocarbon, SCBA, medical gas) are fully discharged in a controlled bay with appropriate scrubbing or recovery, depending on the agent. Halocarbon discharge is captured for return to the agent supplier or for environmentally compliant venting per the listing. Wet chemical is neutralized and disposed under Brevard County and FDEP guidance. Dry chemical is captured for proper disposal. Once discharged, the valve, gauge, hose, horn (where applicable), and any internal tube are removed and tagged for either reuse, recharge, or disposal. CO2 cylinders go through the same pull-and-tag sequence with cryogenic-aware handling.
Every cylinder passes through external visual inspection per the CGA C-6 (steel and aluminum) or CGA C-6.1 (composite) sequence: dents, gouges, cuts, bulges, fire damage, arc or torch burns, paint defects exposing metal, leaks, valve thread integrity, foot ring or boot integrity, and corrosion. Beachside hotel CO2 cylinders pulled from coastal salt-air properties get extra time on this step because Atlantic exposure rejects more cylinders here than inland routes. Internal inspection uses a borescope or rigid scope per CGA C-6 Appendix A and the manufacturer's manual. Aluminum cylinders also get checked for sustained-load cracking around the neck per CGA C-6.1 because certain pre-1990 aluminum cylinders fall under FAA Service Bulletin 2003-1 inspection criteria. Any cylinder that fails visual or internal inspection is condemned per NFPA 10 Section 8.7.5 and removed from service before the test stand.
Cylinders that pass visual inspection move to the water-jacket pressure test stand. The cylinder fills with water, gets sealed inside the jacket, and pressure is applied to the manufacturer's stamped test pressure (typically 5/3 of service pressure for DOT 3AA and 4BA cylinders, lower for some compositions). The test holds for the prescribed duration. Total expansion (volume of water displaced) and permanent expansion (residual after pressure release) are measured. Permanent expansion exceeding 10% of total expansion (or the lower threshold the manufacturer specifies) means the cylinder fails. Halocarbon clean-agent cylinders, CO2 cylinders, SCBA bottles, medical gas, and propane bottles each follow their specific test pressures and durations per DOT 49 CFR 180.205 and 180.213. Composite SCBA bottles add carbon-fiber and matrix inspection, with end-of-life retirement after the listed cycle (typically 15 years for DOT-CFFC certified composite SCBA).
Passing cylinders get the requalification stamp: the testing facility's RIN, the date (month and year), and the test identifier, applied to the shoulder per DOT 49 CFR 180.213(d). Steel and aluminum cylinders take the stamp directly. Composite cylinders take the stamp on the listing label per DOT-CFFC. Failed cylinders are condemned: the shoulder receives a defacement mark (typically an X or a stamped CONDEMNED) so the cylinder cannot re-enter service, and we destroy the cylinder per DOT 49 CFR 180.205(i) when the customer authorizes disposal. Aerospace customers often retain condemned-cylinder records for traceability against their property accountability log; we provide the destruction certificate and photo evidence.
Passing cylinders move to recharge: new valve seal where the listing requires it, new gauge where appropriate, new hose and horn where appropriate (CO2 horns inspected per NFPA 10 Section 7.3.6 every annual maintenance), agent recharge to listed weight, and pressure recharge with nitrogen, dry air, or the listed gas mixture. Six-year internal maintenance per NFPA 10 Section 7.3.3 (stored-pressure dry chemical) gets the new internal seal and the maintenance label. Each cylinder leaves with a new service tag, a record-of-completion sheet, and a portal entry. The audit pack includes the test date, the test technician, the test pressure, total and permanent expansion measurements, pass or condemn status, recharge weight, and the RIN stamp photo. We file the audit pack inside the customer's portal and (where the AHJ requires it) with the AHJ.
Aerospace SCBA bottles for KSC, CCSFS, Patrick, and prime contractor confined-space and rescue teams carry both DOT and NIOSH requirements. We test under DOT 49 CFR 180.205 for the cylinder and verify the bottle is still inside the manufacturer's life cycle (typically 15 years for DOT-CFFC composite). Halocarbon clean-agent room cylinders (FK-5-1-12, FM-200, IG-541) get every-5-year hydrostatic with manufacturer-specific procedures, and we coordinate the abort lockout, the pre-discharge logic, and the room re-arming with the suppression contractor and the FACU technician so the room is back online before the next mission.
Healthcare medical gas cylinders (oxygen, nitrous oxide, medical air, nitrogen, carbon dioxide, helium-oxygen) follow DOT 49 CFR 173.34 and Joint Commission EC.02.05.09. We coordinate with the hospital plant operations director, central supply, and the medical gas system verifier so that the testing window does not interrupt clinical operations. Cruise terminal and marine SCBA at Port Canaveral coordinate with the cruise line shore-side facility manager and Canaveral Port Authority risk and environmental teams. Beachside hotel and condominium CO2 cylinders get weight-loss inspections quarterly per NFPA 10 Section 7.3.4 and hydrostatic every 5 years per Section 8.3.
NFPA 10 Section 8.3 governs portable extinguisher hydrostatic intervals. DOT 49 CFR 173.34, 180.205, and 180.213 govern compressed-gas cylinder requalification for shipping. Florida Chapter 633 F.S. and Rule 69A-60 F.A.C. tie those federal references to Florida licensure of the testing facility and the technician. Our portal stores the requalification history per cylinder so that the customer can pull a route summary, a single-cylinder history, or an audit-pack ZIP for a State Fire Marshal walk, a Joint Commission survey, an Air Force or NASA audit, a Coast Guard inspection, or an insurance loss-prevention engineer's annual visit. Stamps, photos, and pass-fail records remain available for the regulatory minimum retention period.
