Is Propane Flammable?

Propane is highly flammable when in its gaseous state – it can ignite at concentrations between 2.1% and 9.6% in air and burns at temperatures over 3,500°F (1,927°C). However, liquid propane (LPG) stored under pressure is not flammable until it vaporizes into gas. In this guide, we’ll explore propane’s flammability characteristics. You’ll also learn about …

Why Do Rockets Use Hydrogen Fuel?

Rockets use hydrogen fuel because it delivers the highest specific impulse (efficiency) of any chemical propellant, producing more thrust per pound than any other fuel. In this guide, we’ll explore why hydrogen has become the preferred fuel for many space missions. You’ll learn why its unique properties make it indispensable for modern rocketry. Unmatched Energy …

Does CO2 Displace Oxygen?

Yes, carbon dioxide (CO2) displaces oxygen, especially in enclosed spaces where it can accumulate due to its higher density than air. This displacement happens because CO2 molecules take up physical space that would otherwise contain oxygen, potentially creating dangerous oxygen-deficient atmospheres. In this article, we’ll explore how oxygen displacement happens in more detail. We’ll then …

At What Pressure Does CO₂ Liquify?

CO₂ liquefies at pressures ranging from 5.11 bar (at -56.6°C) to 73.8 bar (at 31.1°C), with the exact pressure requirement depending on temperature. Above 31.1°C, no amount of pressure can liquefy CO₂ as it becomes a supercritical fluid. In this guide, we’ll explore the specific pressure requirements for CO₂ liquefaction at different temperatures. You’ll then …

Is Krypton Reactive?

Krypton is not reactive under normal conditions due to its complete valence electron shell, which makes it chemically inert like other noble gases. Still, it can react with fluorine under extreme conditions to form compounds such as krypton difluoride (KrF₂). In this guide, we’ll explore the reactivity of krypton in more detail. You’ll learn about …

Is CO2 Explosive?

Carbon dioxide (CO2) is not chemically explosive or flammable. In fact, it has a flammability rating of zero according to the National Fire Protection Association (NFPA) classification system, and it’s actually used in fire extinguishers exactly because it doesn’t support combustion. Still, this doesn’t make it completely safe. In this guide, we’ll explore CO2’s safety …

Medical Air vs Medical Oxygen: What’s the Difference?

The key difference between medical air and medical oxygen is that medical air mimics natural atmospheric air for general respiratory support, while medical oxygen is a highly concentrated form used when patients need extra oxygen for critical care. Below, we will go into detail on the differences between medical air and medical oxygen.  WestAir supplies …

How Do You Know If You Have a CO2 Leak?

You can identify a CO2 leak through specialized detection equipment. As CO2 is colorless and odorless, leaks are impossible to detect with human senses alone until concentrations reach dangerous levels. That being said, you can still recognize physical symptoms of exposure and observe environmental changes.  In this guide, we’ll explore the key methods for identifying …
