Oxygen cylinders typically need to be tested every 5 years to ensure they meet safety standards and are in proper working condition. This process is called hydrostatic testing and helps identify any potential issues or weaknesses in the cylinder that could pose a safety hazard.
Oxygen cylinders come in various sizes including D, E, M, J, and K. The specific size is often measured in liters of oxygen capacity, with common sizes being 415, 682, and 1590 liters.
Biogas has a lower energy density compared to LPG, so it would require larger storage cylinders to store the same amount of energy. Biogas also contains impurities like moisture and hydrogen sulfide that can degrade storage cylinders over time. Additionally, biogas is often produced on-site in decentralized systems, making large-scale storage in cylinders less practical.
Typically in the laboratory setting, hydrogen gas is often tested using the reaction between hydrogen and oxygen gas. This reaction forms water as the product. The presence of hydrogen gas in the reaction can be confirmed by observing the formation of water, such as condensation or droplets on the surface.
No, oxygen is not a vasopressor. Oxygen is a gas that is essential for life and is often used to support respiration in various medical conditions by increasing the levels of oxygen in the blood, but it does not have direct vasoconstrictive effects like vasopressors do.
Around 16% oxygen is required to sustain a fire. This level is often referred to as the "minimum oxygen concentration for combustion." Fires can be extinguished by reducing the oxygen level below this threshold.
Gas cylinders should be re-tested every 5 to 10 years, depending on the type of gas and the regulations in your specific location. It is important to have cylinders inspected regularly to ensure they are safe for use.

Ambulances carry oxygen cylinders because it is often used to revive people, e.g. For people rescued from drowning or people rescued from smoke filled rooms.Hospitals also use it for patients with breathing difficulties e.g. asthma.
Scuba Cylinders must be tested VISUALLY (called a visual test !!) every 2.5 years. They must have a HYDRAULIC test every 5 years (previously 4) (hydraulic is also known as hydrostatic testing)
Often it takes 10 or more years for drug to be approved in the US. For example the vaccine for chickenpox was being used in Japan before 1980 - we finally got the vaccine here in 1995.
Hydraulic cylinder use a liquid medium, often some type of viscous oil, in the cylinders and can be subject to higher pressures then pneumatic cylinders which use air or some other gas and work under a lower pressure.

State laws do not speak to how often a person can be randomly drug tested at work. The policy of the company you work for does.
For a fiberglass wrapped SCBA cylinder it is recommended that the cylinder has a hydrostatic test every three years for any leaks or flaws. A fiberglass wrapped SCBA cylinder is also expect to have a service life of 15 years.
