A hydro test is an approved way to test the structural integrity of a compressed gas container. It is performed by removing the valve, filling the container with water, and then pressuring the container above its operating limit. The expansion of the cylinder is measured, recorded, and analyzed.
Cylinder hydrostatic testing is something that a wide variety of organisations have to consider. As per Australian Standards 2030.1 -2009 Gas Cylinders – General Requirements, SCUBA cylinders, SCBA cylinders, portable CO2 fire extinguishers, suppression system, ANSUL and air bank cylinders all need to be regularly hydrostatically tested. Hydrostatic testing is generally conducted to ensure both the maximum performance and safety of a wide range of cylinder applications
That’s a good question! Before we can answer why pressurized cylinders need to undergo hydro-static testing, let’s break down the basics of hydro-static testing procedures and what the tests determine.
Let’s define hydrostatic testing:
A hydrostatic test is a process in which pressure vessels (such as cylinders) are tested for strength and leaks. Essentially, hydrostatic testing works by completely filling the cylinder up with water, removing the air in the cylinder, and pressuring the system higher than the cylinder’s design pressure limit
The purpose of a hydrostatic test is to test the strength of the pressurised vessel. Hydrostatic testing is conducted to expose any leaks, weaknesses, faulty components, or damage. If a pressurized pipe, cylinder, or vessel passes the hydrostatic test, it passes a national Australian standard under AS2337.1 Gas cylinder test stations Part 1: General requirements, inspection and tests – Gas cylinders and AS2337.3
Gas cylinder test stations Part 2: Transportable gas cylinders – Periodic inspection and testing of composite gas cylinders

Nitrogen purging is an industrial process where unwanted gases and other impurities are eliminated from a manufacturing system environment using nitrogen gas. Due to its inert properties, nitrogen can be used to effectively displace oxygen and other pro-oxidative gases from industrial processes without reacting chemically with the substrates
The benefits of nitrogen purging are numerous, but the most crucial reasons for nitrogen gas purging are to prevent chemical alteration of products and to prevent moisture-related equipment damage or even combustion
presence of moisture or oxygen-rich air. The oxidative damage caused by these unwanted impurities will diminish the quality of the final products with costly implications for profitability. Oxygen-sensitive operations integrate nitrogen purging equipment to prevent unfavorable manufacturing conditions
Most people think of the medical gas system as a pipe that pumps oxygen to patients in surgery or into their hospital room. In fact, there are several gases that make up the average medical gas system, including the anesthesia gases that are part of the cart in the operating room.
Medical gas systems sustain life and the gases they contain are regulated as a drug. Using medical gas systems properly includes navigating multiple layers of restrictions and instruction on the proper, safe and legal way to do things.
According to CBC News, the first recorded medical gas cross-connection deaths were at a former Sudbury General Hospital in Canada back in 1973. Codes were implemented to prevent future medical gas-related deaths requiring third-party verification and system installation certification.
The concern for patients and the efficiency of hospitals has led to several layers of oversight of medical gas systems from the government (CMS and OSHA), their agents (TJC and NPV), and the industry in the NFPA 99-2012 code. While all these organizations have oversight and regulatory power over medical sites using gases, their regulations often need to be more consistent.
Since there is so much scrutiny concerning medicinal gas systems, most hospitals hire third-party inspectors annually to check every element of their system.
A third-party inspector confirms that the medical gas systems are functional and meet the standards set by the organizations above, ensuring the safety of patients and staff. Not passing a medical gas inspection (or receiving citations) can affect a hospital’s reimbursement and/or accreditation status.
This guide provides an overview of medical gas systems, including:
Fire suppression systems are used to extinguish, control, or in some cases, entirely prevent fires from spreading or occurring. Fire suppression systems have an incredibly large variety of applications, and as such, there are many different types of suppression systems for different applications being used today.
