National Fire Control offers hydrostatic testing services of most types of D.O.T. rated cylinders, both steel and aluminum. At our Kona facility, we have our high pressure hydrostatic testing lab where competent testing and safety are stressed. At our Maui, Kauai, and Oahu labs we can quickly turn-around low pressure cylinder testing with careful handling of cylinders as our top and most important consideration. Most cylinders can be tested and back in service in 2-3 working days. Our technicians are trained and certified to meet D.O.T. requirements and our facility is licensed, certified, and monitored by the U.S. Department of Transportation.

Hydrostatic testing is a nondestructive test required by the Department of Transportation to insure the integrity of pressurized cylinders. These include everything from small fire extinguishers, to Self Contained Breathing Apparatuses (SCBA) used by fire departments, to CO2 cylinders used for soft drinks, to medical and industrial oxygen cylinders, to Nitros cylinders used for race cars and SCUBA tanks used by divers.

Hydrostatic testing for different types of cylinders is required at different intervals.

All DOT-3AL marked CO2 cylinders are to be inspected and hydrostatically tested every five years as required in CFR Title 49 Part 180.205(c). Cylinders still with charge at the time the 5 year test is due, do not have to be tested until the charge is used, but prior to the re-filling of the cylinders.

High pressure, fiber wrapped aluminum cylinders, such as those used by fire fighters must be tested every three years and must be decommissioned after 15 years.

Additional information can be found in the Code of Federal Regulations (CFR) 49, under "transportation".

First, the cylinders are visually inspected. Visual inspection, at the time of hydrostatic testing, must be performed by a DOT licensed test agency. Visual inspection must be performed in accordance with CGA pamphlet C-6.1; Standards for Visual Inspection of High Pressure Aluminum Compressed Gas Cylinders. Internal and external visual inspection of a cylinder is performed prior to hydrostatic testing.   The visual inspection includes:  checking for cracks and fissures, sidewall stamps, rust, and verifying the correct tolerances for outside diameter, wall thickness, length and straightness.

Next, the cylinders are put under pressures of over 66% higher than their normal working pressure.  Hydrostatic testing must be performed by a DOT licensed re-test agency. Hydrostatic testing must be performed in accordance with CGA Pamphlet C-1; Methods for Hydrostatic Testing of Compressed Gas Cylinders. 

Once a cylinder has successfully passed all visual inspection and hydrostatic test requirements, it is to be permanently marked with the test date, month and year, and licensed test agency's number in the proximity of the previous hydrostatic test date.  No cylinder is to be marked with the licensed test agency's number until the cylinder has passed all visual inspection and hydrostatic test requirements. No cylinder is to be marked with a licensed test agency number by any other person or agency other than the personnel of the licensed test agency.

Fire Hydrant

NFPA standards require that all public fire hydrants be inspected on a regular basis. Fire hydrants can be affected by a number of outside factors, including regular wear-and-tear, accidental damage, vandalism, mechanical function and even contractors who forget to turn them back on after a job. If your Hawaiian building's fire hydrant needs inspection, call National Fire Protection today. Our certified trained technicians can ensure that your fire hydrant stays up to code and will be able to protect you and your business in the event of a fire.

Fire Hydrant Inspection Process

At National Fire Protection, our fire hydrant inspection process is designed to ensure that your building's fire hydrant meets all proper codes. We start by opening your fire hydrant fully and letting it flow for at least a full minute. This clears all foreign material out of the fire hydrant and lets it run as smoothly as possible. After stopping the flow we observe the fire hydrant and make sure it drains properly. Finally, we lubricate all fire hydrant stems, threads and caps to make sure they are in proper operating condition and will be easily accessible to the fire department.

Fire Hydrant Inspection Precautions

Because of the dynamics of water, there are a number of things that must be taken into consideration when testing out a fire hydrant.

Water Hammer

Water hammer is caused by an abrupt stop of fast moving water. It usually occurs if a valve is shut down too quickly. The effect of fast moving water slamming into a valve is the same as the effect of a fast moving car slamming against a brick wall.

Since water is incompressible, it does not absorb any of the energy from a high velocity impact – instead, it transfers it to the system, pipes, hydrants and ground, which can lead to cracking and all out destruction of the fire hydrant. At National Fire Protection, we take care to keep your fire hydrants safe from water damage during inspection.

Brown Water

Brown water is caused by a sudden change in the amount of water in a water main, such as the increased water flow from opening a fire hydrant. When water starts flowing faster, it kicks up sediment that usually stays on the bottom of the pipes and moves it with the water. There is nothing harmful about the sediment in water pipes, and at National Fire Protection, we work hard to keep the brown water out of your faucets during our fire hydrant inspections.

Is your Hawaiian building's fire hydrant ready for inspection? Call National Fire Protection today to make sure your hydrant is up to code and able to protect you in the event of a fire.

Emergency/Exit Light
